[Q] Bluetooth Audio Quality - Thunderbolt Q&A, Help & Troubleshooting

Question,
Using bluetooth to play audio from Pandora sounds terrible. Lots of static, studdering, skipping, cut outs.
If i use a stereo cable it sounds great, so that rules out software.
My atrix sounded gorgeous over blue tooth, so that rules out the equipment.
Anyone else have any sound quality issues with the bluetooth?

No issue so far, use for about 4 hours a day for conference calls and then pandora/slacker or doubletwist for 2-3 hours more. Using Samsung sbh600 bluetooth.

I use A2DP stereo streaming to two different devices (car and supertooth disco) and it sound excellent! Much better than my old evo and just as good as the nexus S I had for a while.
If you are using wifi for the connection to Pandora, try switching to 3G or 4G. Wifi and bluetooth can interfere with each other as they use the same frequency. I haven't had any issues, but have seen it before with other devices.

I noticed the same thing today streaming to my kenwood unit. My droid X had flawless sound, this was exactly as you described. Any fix yet?
One thing I noticed, my X had a check box for an enhanced bluetooth audio quality....not sure if that made a difference or not.

Been using the phone in my car with my alpine deck without issue. I have the add-on bluetooth from alpine and it works really good with the phone. Randomly the music cuts out for a second but my old blackberry did the same thing, and so did my iPod Touch (2nd gen).
Shutting off the wifi on the phone isn't a bad idea... might give that a shot to see if that helps your issue? My blackberry would randomly distort the music. I would close pandora and do a battery pull then it would usually be back to "normal".

I have the same issue with my Clarion deck. Of course...I've somewhat convinced myself the speakers are a bit blown...but it's worse on BT than wired. From what I've been able to read there is a "bitpool" setting which controls the quality, and by default it's pretty low in the 30's, while it can go up to the 50's and the sound quality is noticeably different. CM fixes this from what I've read, but that's all. Apparently Blackberry has a higher setting by default, and each manufacturer can set their's different.
I'm hoping that a combination of new speakers and CM7 will remedy my issue.

interesting I've got a pioneer premier DEH-P710BT
and it sounds amazing
maybe look for a firmware update for your receiver?

mine is updated to their most current firmware. I'm more inclined to think it's a bad bluetooth stack like weiln12 mentions above. gonna try it out with my friends thunderbolt tonight and see if it is the same.

I also have a clarion deck and find the bluetooth audio quality to be horrific. I find it hard to believe that it's the head unit at fault since my old Droid1 sounded perfectly fine.
Is anyone aware of any roms or kernels that have a higher bitpool setting?

I haven't found any yet. I'm hoping when we see CM7 things will be better.

Sounds absolutely perfect on my Ford Sync audio.. I have a Scoche Bluetooth in my other car that I can test.. I haven't tested as it is currently off the road. I will let you know. With my Scoche and past phones I noticed the bluetooth is a little lower quality then the audio jack but not much and only with that unit.

I have a Motorola S305 headset that works very well with music (slacker, amazon mp3, and pandora). However, my bluetooth Samsung WEP570 sounds so bad, crackled, and quiet (even on max volume) that I don't even use it anymore for calls.

How is your call quality on the Ford sync? Specifically the incoming call volume.

I'm streaming Pandora to a MOTO roadster, then over fm to stereo, sounds great, no loss on the bass end either.
Have you tried another bt device?

I personally have tried a few and have problems. However, I've tried multiple thunderbolts and they all sound the same on my kenwood. I've definitely read about HTC using less than stellar bluetooth on their units before, so I am assuming that is the case here. I guess it just works ok with some and not with others. Testing my X on the same kenwood unit I have and it's crystal clear with no distortion.

This has absolutely nothing to do with the quality of the bluetooth hardware itself. Bluetooth is a wireless digital transfer protocol, nothing more nothing less. It does nothing to the audio quality during it's transmission. Where we have a problem is in the amount of "space" (the bitpool) provided to send the information from your device to the receiver. The lower the bitpool, the less space is available for your music and the more it must be compressed. Motorola may infact provide a higher bitpool setting in their devices than HTC which would account for them sounding better and I also know that the X has a "Use High Quality Bluetooth Audio" setting, which I'm sure enables a higher bitpool.
The type of music you listen to also has a significant effect on how this sounds. If you listen to something that is sonicly simple (ie hip hop, pop, etc etc) it doesn't need as much "space" to sound good. However, when you switch over to music that has more going on like heavy metal, it needs more room.
I can give you a perfect example. I was listening to Rage Against the Machine today. In the slower parts of the songs, it sounded GREAT, but then when it picked up and the song got more involved there was a huge loss of fidelity and it didn't sound very good at all.
Now, for those of you who are happy with how yours sounds, that's awesome, but for those of us who are not, we simply just want to know of a way to adjust the bitpool setting or find a developer who is willing to code it in to their kernel/rom which I believe is what needs to happen.

Amen. You just summed up the situation perfectly. I forgot the X has the check box for high quality BT audio, that could very well be what makes it better. I'm going to check it out tonight w/o that checked and see how it fares. Not sure why HTC wouldn't have an option like that.
Just found a post here that seems very related. http://forum.xda-developers.com/showthread.php?t=708685
Apparently CM uses an open source BT stack that has good settings to use the higher bitpool but HTC chooses the Broadcom stack that utilizes a much lower bitpool as stated above. They don't seem to have a way to raise this value though....

i've had no issues. I use Pandora w/ high quality audio over BT into my Ford Sync system.
Sounds great. Somewhere between satellite radio and MP3 player SNR ratio.

Ironically my streaming audio is fine from mp3's i put on the SD, but IN CALL volume is much lower then i am used too, i have a Jabra BT530, its weird because the media volume is fine, but as soon as a call comes in i have to switch to the handset to hear the other end well.

I had that problem but it turned out to just be a volume issue, BT vol was set way higher...
Again, Streaming pandora to Motorola Roaster, which in turn broadcasts FM to my car stereo. It sounds fantastic.

The search for the perfect BT Headphones \ Handsfree

I bought the Logitech FreePulse BT headphones about a year ago and have been in love with them ever since. The fit and design aren't that great, and it doesn't have buttons for changing the songs. However, all of this is made up for by the amazing sound quality.
I have been using them religiously ever since...with my laptop, desktop (with the provided receiver) and Touch Cruise.
I decided it was time to upgrade, and get something that had what these dont; buttons for changing the songs, a mic, and the ability to switch between calls and music; all with good sound quality.
A friend recommended the Motorola s9's. I tried them, and absolutely hated them. I loved the features that they had, and I loved how lightweight they were...but the sound quality was so bad -- it was tinny, no bass at all, crackly, and hollow...like something I would expect from a pair of headphones that come free with another product.
I returned those, and then purchased the Motorola HT820's on ebay. These were a bit heavier, but I liked the fit better. These also had the buttons for switching between songs, and had a mic for calls too. However, they suffered from the same issue as the s9 - absolute crap sound quality.
I have been checking out alot of different reviews for other products, and am stuck. People never seem to agree about anything, and the reviews are always mixed.
So, I'll ask you guys here at XDA..
What do you think the best quality BT headphones are, that also have a mic, and remote control buttons?
Are there any studio quality monitors like ultimate ears that use bluetooth a2dp / handsfree?
Thanks in advance for your posts...I hope I can find something decent
Has anyone experience with the motorola s705 soundpilot in combination with the touch cruise?
Jabra bt320s: imho this is the best; buyed from ebay.co.uk 1 month ago and no problems at all:

Plantronics
I have plantronics 665 & with BTArouter its great but no a2dp,
Check the plantronics 855 it should be the best BT headset exist.
i bought a Sony Ericsson HBH-DS980 and its just perfect,
Basses are deep, and sound quality is just like my PC Speakers(logitech 5500 digital...)

Ha, I thought I was the only one. The Logitech simply are amazing in terms of sound quality, bar none. I just wish they had the AVCRP and handsfree profiles and I could deal with the fit issues and the fact that its kinda bulky. Honestly, I can't say anything is better and I've tried many. Unless Sony has vamped up its game in the last 6 months, they don't compete at all...although maybe the SonyEriccson line is better (althought I got into A2DP to avoid tangled wires, so earbud form factors are not an option for me). I have high hopes for the Jabra BT8030 though and may pick them up one day as an addition to my current A2DP headphones. The BT8030 certainly looks like it has awesome sound.
I personally use Samsung SBH-170 mainly bc of their convenience and small size. The sound was better than everything else I had tried, but nowhere near the FreePulse. FYI the FreePulse is the only headset that you could turn the Bluetooth A2DP thoroughput/bandwith all the way up on the PC w/o any stuttering.
Thanks sonus, those samsungs look really nice
However, I have given up and am stuck with the freepulse for now..
All the ones i've tried from best buy \ circuit city suck compared to those, sound quality wise. I do agree that the fit is not the best, and others are way better, but since I'm a musician \ producer my main concern\priority in the end will always be sound quality.
I would try to order some online; but alot of places don't like people returning things and then they take a month to refund your card, etc. :-\
I saw some real good ones on ebay a couple weeks ago, but I forgot what they were called. They were labled as professional audio quality, so I'm gonna check into those for now I guess.
I still have a2dp issues with the freepulse + polaris tho..like lag, skips, weak signal, etc. Do you have the same problem sonus?
No, I don't have any serios A2DP problems, although maybe once every 15min I might get a skip. Have you tried editing the A2DP settings in the registry?
HKLM/SOFTWARE/Microsoft/Bluetooth/AD2P/Settings/BitPool
Reduce this value to lower the standard bitpool that is used the majority of the time
30-40: Medium audio quality
48: High audio quality
58: Excellent audio quality
HKLM/SOFTWARE/Microsoft/Bluetooth/AD2P/Settings/MaxSupportedBitPool (Default=64)
Reduce this value to lower the maximum bitpool that is used when your MP3 player encounters high bitrate songs. I'm guessing that since you are a musician and since you probably have high quality mp3s, this value might be your issue. Try lowering this before reducing the bitpool setting.
HKLM/SOFTWARE/Microsoft/Bluetooth/AD2P/Settings/UseJointStereo
0=Real Stereo
1=Joint Stereo
Turn your bluetooth off then on to make the changes take effect. Lower values will also give you better battery life, and reduce processor usage while a2dp is being used.
Thanks very much for the info..i changed both values to 50 and turned on true stereo (I can't believe joint stereo was enabled by default -- YUCK!) It seems to have helped..
I just listened to four songs in a row using core player and I only got 3 skips..believe it or not that is a big improvement
But the problem when coreplayer is playing and i press the power button it still skips for 2-3 seconds every time.
It's better, but I still am kind of suspicious because my laptop and desktop have 0 skips at all, no problems whatsoever...but i guess mobile devices are different sooo..yuh..I'm somewhat content now at least =]

It might be that HTC underclocks our devices when the power button has been pushed. So try a lower bitrate, experiment with a value like 45 or even 40 to see if the music quality is audibly degraded, you should get no skipping at that point.
yeah, it definately has something to do with the bluetooth settings too because when i have the audio adapter connected (Wired) to my car's aux i can push the power button all day long and no skips, and really no skips when playing songs at all in core player...maybe when a notification comes up but thats to be expected i guess
I bought this BT headset, works perfect with the TC and not expensive:

V Three BTH-18
I bought the V Three BTH-18 Bluetooth Headset from expansys and I have to say that it's working very well. No problem pairing, answering or making calls with voice speed dial. Also it's very small!! (Mind you, I've not tested it with programs like coreplayer, etc, for music or movies...! I suppose I'm not interested in that feature)

I don't know if anybody tried it. I have a choice now of getting Sony Ericsson DS980 or this new Sony bluetooth. Looking for a feedback about this device, but can't find it. Maybe someone can share his experience with this toy? Thanks!
I think these are the best I've ever heard
the Sony DR-BT22 they fit perfect on the ears sound quality is awsome ....I know that I have a Kaiser but stereo headsets work with all devices.
Peace
mike
I bought I-tech Clip D Radio! Work awesomely!!!
BT2.0 if possible as that should theoretically support higher bitrates. The vast majority of stereo headphones are BT 1.2 however. For the most part newer 1.2 headphones will work just fine.
I have a Nokia BH-503. I think it's great (good sound, easy to use controls for music and calls, and very comfortable).
Only problem is that after I turn it off, when I turn it on, even though it reconnects in phone mode automatically, I have to manually reconnect for music. I think this is a problem with other headsets as well though.

Rezound Sound Quality on BlueTooth

I know I'm early to the game as not many people have this pre-launch... but for those of you who were lucky enough to get your hands on one [or if this thread persists to launch date...] :
Is it just me, or does the sound quality when streaming BT just plain awful? I can't find anywhere in the settings to adjust the EQ when on BT. I'm fearing that the sound quality was tuned specifically for the included iBeats headphones (which are pretty good so far).
I spend a lot of time commuting, and used to use my Thunderbolt as my primary music source (streaming BT to Lexus IS350, which has a great sound system)... I've spent 2 days with the Rezound, and am seriously considering going back to the TB.
Anyone having similar experience? Am I dumb and there's a setting somewhere?
well, no re:Zound here yet, but my experience using bluetooth for music just isn't as good as going through AUX.
Ive spent about $2,000 on the speakers, amps & subs in my car and tried using my TB both through AUX and BT. I found the sound quality to be noticably better with the AUX. You can get a short 3' gold tipped cable at Radio Shack for about $5 - $10.
Yeah, my wife's Bluetooth (Moto ROKR) unit does a pretty poor job of reproducing music from her phone. It's good enough for her, I guess. I have not tried the Rezound on her system yet. If I get a chance, I will let you know.
I have tried the Rezound on my Line In in my car, and the extra bass is a little annoying. I turn up the bass in my car as it is, for radio playback, CD playback, Pandora playback, etc. When I start the HTC music player, my normal bass settings add to the Beats bass amplification and things are a little over-the-top in the low end.
That's to be expected, Dan. Your car has an equalizer built in, so you're putting one eq over another. Turn beats off or use the other dolby or whatever one, then use your cars eq...or turn down your cars eq and use beats. That eq was designed for headphones, though
Sent from my ADR6300 using XDA App
The thunderbolt has Bluetooth 2.1 and the Rezound has 3.0
Differences between them is 3.0 uses less power, transmits at a higher distance, but has lower quality. It really is meant for phone calls and not music, I'd suggest finding an FM transmitter or AUX line if your car has it. Both are really cheap and much higher quality than even the 2.1 bluetooth.
about the EQ bit, yeah... since i have the subs in back, i let them handle the low's 100%.. all the other speakers handle just the mids/highs.
oh and i remember when i went to get my head unit at a local car audio shop, i mentioned using blue tooth for music and the salesman gave me a strange look and stated that blue booth isn't geared towards music and said to stick with aux. heh

[Q] bluetooth audio streaming problem?

so i just got my htc rezound like 2 days ago and so far its wonderful (coming from a droid razr). the only stipulation im having is streaming audio via bluetooth to my car's stereo system (ford fusion with sync system). it sounds really crappy using the standard player htc gives you, but if you switch to amazon mp3's player it sounds good except for certain pitches and frequencies sound like crap. it almost sounds like crackling but not quite. gives it good bass back tho. so is there a way to fix this? i did unlock my phone like 4 hrs after getting it from the fedex guy. is there anything i can do to it go improve on the audio quality or is this gonna be a "wait for ICS and see" kinda deal?
Try PowerAmp or install a rom with DSP so you can tweak the audio settings.

k will give it a shot later tonight when i leave for work. i honestly dont think it has anything to do with the eq but i'll try it. i think its something with the bluetooth radio thats built in....maybe its just a crappy design idk.
any other ideas in the mean time? or anyone else having the same issue?
Never heard of this problem with differences between players.
Stream all day with my phone and only problems are with ICS not GB.
I have a Ford Focus (with sync) and mine sounds pretty good, but not as good as when I had full time beats on my EVO3D. They only thing I do is turn the volume up on the phone while its playing through the speakers. I do this but using the volume rocker on the side during playback. Its not as good as a CD but not too bad either. Tried to get the guy that fixed it on the 3D to look at the Rezound but he never responded to my PM. I have played with DSP Manager and you can get some improvement. Also other EQs exist in the market that can improve the quality.
<3 ford focus, are you saying it just lacks an equalizer's touch or does it crackle? =o
No Problem
I use the MotoROKR T505 for my car. Bluetooth stereo music over the car speakers is never a problem, regardless of using stock player, meridian, or poweramp.
Zone is right. Turn the volume all the way up. It took me awhile to figure this out. I think its radio interference that you're hearing.

well i tried poweramp from the market and it made some improvement...but still not as crisp as i'd like. it seems like with some of the higher frequencies over bluetooth it kind of mashes them together sort of. idk but coming from a droid razr i can definitely tell a difference. that phone was amazing when it came to audio quality over bluetooth. for now i guess i'll try to rig up the usb cord so my sync system can read the files from my phone or either buy a cheep aux input cord for my ford....until ICS is released....hopefully they made some type of improvement.
edit: i always have the volume maxed out via the rocker on the side....learned that day 1 of having an ipod long ago lol. the droid razr definitely puts out cd quality audio over bluetooth and i was kind of expecting this phone to do the same or better, not sub-par performance.
I wonder if that is the razr's 4.0 bluetooth that provided so

Bluetooth audio quality?

So.. I bought the DNA today and am severely regretting this decision.. Wondering if anyone has experienced the same issue?
I have a Jaybird BlueBuds X bluetooth headphones. Compared to a lot of others, they have an amazing sound quality.. at least they had an amazing sound quality. When they were connected to my Galaxy S3 (running CM10.1 in the interest of full disclosure), they sounded as if they were hard-wired - no distortion, no buzzing, perfect sound quality.
I paired them with my new DNA, hoping for the same audio quality (and then some, due to famed Beats Audio) and... didn't get it.
So the problem I'm running into here is that they now sound like a pair of cheap, 10$ bluetooth headphones - the sound is distorted, there is crackling noise in the background, the music sounds like as if it's 64 kbps - barely usable, very unpleasant. As soon as I pair it back to my old S3, the sound comes back to life.
I've read the forums and understand that the OTA pushed out an update with some bluetooth fix.. I have the OTA (got it that way), so my phone is already running the supposed sound fix.
Has anyone experienced same problem? Especially with higher-end BT headphones? (Jaybirds, Sennheissers etc) Really like the phone, have been an HTC fan since WinMo days, but I simply cannot tolerate this BT flaw... Does it have to do with the BT chip that DNA has, or is it the BT stack/driver on this one?
++> On a side note - sound quality over wire is great.. so this a bluetooth only issue. The issue (noise) is more pronounced on higher frequencies..
I don't have BT headphones, but do have a Sony Xplod CD deck in my wife's Honda & pairing any of my HTC phones via BT sounds so horrible. However, I did get the HTC Steroclip for my Sony Xplod CD deck without BT in my truck & it sounds great. What gives? Was wondering if it might be the same issue as with the headphones.
I am running Creative 350's with apt-x codec and they sound great. I would find a set of headphones with apt-x. You won't be disappointed.

Well, quite honestly, when i first started researching bt headphones for exercising there has not been a single pair that garnered the amount of positive reviews as the bluebuds.. plus they did sound amazing on s3. I did look for aptx - s3 uses it, but no workout headphones that had aptx had good reviews in terms of build quality etc.
I do wonder tho...
On dev.android under the about Android 4.2 JB it does mention that it got a new BT stack developed, replacing current BlueZ as well as updated low-latency audio.. maybe the new stack does indeed improve quality.
im going to flash the s3 with stock 4.1 and see how it sounds and then try a couple of variations of aosp stuff and report back..
Ps. I also found a mention of how s3 uses a2dp edr natively, whereas dna is using aptx... Its going to suck if this is truly a hardware issue...

I think Stereoclip has aptx.
So I flashed S3 back to Stock VRALF2, 4.0.x ICS, and played a couple of songs and still was getting crystal clear quality.. So it has to be the BT implementation in DNA.. Sad. Anyone has any insight into why/what could be the root cause? BT chip? DAC chip?
Thanks
If it helps any, Bluetooth audio sounds great in my 2012 Sonata.

Same issue. I streamed music from the same Google Music account, on both my Rezound and DNA, to the same receiver (2010 Infinity G37S).
DNA audio quality is noticeably bad. Especially in mid and high range. It sounds like very low bitrate audio, and/or very lossy compression. The Rezound audio quality over BT is nearly the same as wired.
I suspect HTC has deliberately chose to use a low bitpool value for A2DP w/ the stock Sense ROM. DNA now supports atpX. So, they gimped A2DP stream, with the goal being to sell more of their Bluetooth Stereo Clip product, that support atpX.

I have a set of jaybird freedom's myself and have had no issues with bluetooth, beats audio or audio quality. One thing i have seen though is that some roms do not handle beats over bluetooth very well. The other thing you probably should look at is to make sure that it is pairing as a stereo audio device and not a mono audio device.
+1 for horrible quality here. I use these LG blue tooth ear buds and they just sound terrible. sounded fine on my gs3...and I used one of those jbl stereo boxes and it's awful.. and again fine on the gs3. sucks.

I have a set of Sony bt headphones (bought on amazon a while back for around $40 way before DNA I had Bionic back then) that sound very good I also stream via HTC BT dongle to my Sony xplod in car with with Fosgates all around music sounds GREAT I can really tell the difference when Beats is off even more so when I flash Awesome Beats...I also noticed a setting the other day on my Sony deck for AUX VOL while messing with sub output I turned the AUX volume up now I'm really bumping hahaha

DNA Sound Quality
I hope you haven't given up entirely on your DNA since your post because there are some options you can explore.
Did you try turning off "Beats Audio" in your settings? I purchased the Power Amp music player update and Power Amp and Beats Audio don't work well together. In my experience, the standard Music player that comes with your phone works best with Beats. Other music players may also have the same problem. Second question, did your problem go away with the latest update to Jelly Bean 4.2.2?
Good Luck,

So.. I bought the DNA today and am severely regretting this decision.. Wondering if anyone has experienced the same issue?
I have a Jaybird BlueBuds X bluetooth headphones. Compared to a lot of others, they have an amazing sound quality.. at least they had an amazing sound quality. When they were connected to my Galaxy S3 (running CM10.1 in the interest of full disclosure), they sounded as if they were hard-wired - no distortion, no buzzing, perfect sound quality.
I paired them with my new DNA, hoping for the same audio quality (and then some, due to famed Beats Audio) and... didn't get it.
So the problem I'm running into here is that they now sound like a pair of cheap, 10$ bluetooth headphones - the sound is distorted, there is crackling noise in the background, the music sounds like as if it's 64 kbps - barely usable, very unpleasant. As soon as I pair it back to my old S3, the sound comes back to life.
I've read the forums and understand that the OTA pushed out an update with some bluetooth fix.. I have the OTA (got it that way), so my phone is already running the supposed sound fix.
Has anyone experienced same problem? Especially with higher-end BT headphones? (Jaybirds, Sennheissers etc) Really like the phone, have been an HTC fan since WinMo days, but I simply cannot tolerate this BT flaw... Does it have to do with the BT chip that DNA has, or is it the BT stack/driver on this one?
++> On a side note - sound quality over wire is great.. so this a bluetooth only issue. The issue (noise) is more pronounced on higher frequencies..

Music through Bluetooth sounds terrible

Hey guys. I have a 2017 Subaru wrx. When I connect my v 30 over Bluetooth to listen to my music it sounds tinny and metallic. I'm using Google music to stream music. I never had issues with music over Bluetooth with my previous phones. Any help is greatly appreciated!

What head unit? I have the non navigation unit in mine. Wondering if it'll sound the same.
No issues streaming over to my car, Mazda 3 here. Not sure what to tell you as it's just a digital stream of data between your phone and car. All of the unpackaging is done on the car's side of things. The phone is using the newer BT 5 which allows it to put out a lot more data, so I don't see that being a problem. Check your streaming quality settings in Google Music and if that's set as high as it can go, check to see if maybe your car's system needs an update.

I have the non navigation unit too.
I have problems with podcasts, but music comes through beautifully.
Are you streaming files from the phone or streaming from your own music or listening to streaming stations? If streaming, you can try adjusting the quality settings in google play music.
No issues here with my Hyundai Sonata w/ Infinity headunit. I use standard BT (44 KHz) and Android Auto (48 KHz) and actually find the quality to be improved from my past 3 phones (V20, S8+, Note8).
I get popping and crackling streaming to isimple connect.
Music and podcasts were fine for me. Call were terrible. Lots of static on calls. I has this issue with two V30s. I had to return the phone and go with the GS8+.
coming from my moto pure, which was terrible on the bluetooth with my 2013 tacoma (HU is from a 2015 Tacoma) i had decent sound but it would drop out all the time, this phone is a dramatic improvement. there are more features in play, and the sound quality is as good as can be expected for streaming audio on a stock unit and speakers.
I was just coming in to say the same. Even from my V20, going through a cheap walmart BT - FM Transmitter, the sound is richer on the V30 than it was before, and less static between the devices.
Check your quality settings in Google

Have you tried changing the quality on mobile network settings in Google Play Music? Could be a case the source is low quality causing your distortion.
I've tried changing the quality and there's no difference.
I'm currently struggling with static over Bluetooth in my WRX. This morning I actually did a factory reset on the stereo. I couldn't tell as I was kinda in a hurry to test it too much. I will find out here in about 1.5hrs though.

Do you have Android Auto as an option? I've found BT streaming to be more stable when I use AA in my car. It streams at 48Hz instead of 44Hz.
That being said, I don't have quality issues either way. Just the occasional blip in streaming that lasts less than a second.

I don't have that option unfortunately. I wish I did though. What I've tried so far, just creates the same issue. No way around it as of yet.

I will test tomorrow in my car where I stream over my audio system using a Audioengine B1. So far I tested BT today using my BT headphones and they definitely sound a little different. I think they sound cleaner and very good though. This is compared to my Moto X Pure 2015, which seemed to sound very good also. The overall volume was a little lower than my previous phone but with the vol all the way up it was perfect for me to enjoy and overcome the sound of my lawnmower while cutting the lawn today
So no issues so far.
no problem at all on my jeep with Uconnect
Tested today in my car using my Audioengine B1 (stereo) and car BT (cell), sounds awesome!!
Plus found out since its a metal back plate it sticks to the dash magnet thingy I have vs using the metal plate inside of a case!!
SO far loving this phone.
Nothing useful to add at the moment beyond noting that my 2017 Subaru (BRZ) has the same issue. It appears it may be something unique to the pairing of a Subaru HU and the V30, or possibly just LG. My Sony Z5 works just fine with the stock HU, and the V30 works fine with a very cheap 1DIN HU I have around... I've reached out to Subaru but don't expect anything but finger pointing.
I'll instead likely be changing the HU to something that does Android Auto or even mirror-link... if only it were easy to make any sense of the Android HU offerings! I admit I'd sort-of like to keep the reverse camera and the steering wheel controls. I guess it wasn't worth saving the $800 on the 2017 after all (with 2018 now available for order with a price increase...) - then again, I may like whatever I install better.
I just wanted to add what I found since seems a lot of issues are from scoobies. I have an 2011 Forester XT stock non-nav HU. HU will never auto connect like it did with my HTC 10. But I found out that if I connect it through the HU works like a charm everytime. Before I was going to BT setting on the LGV30 and connecting it that way. And sometimes it would connect and if it did was really spotty, sound would stutter all the time. Drive me nuts. Now with connecting first through the HU works like a charm all the time, and just sometimes their is stutter. For my HU i've attached a pic of where the setting would be. and for me would be to click on "select audio player" and the click V30 and all is heaven.
Hope that helps some fellow scoobies.
