So I was looking at different headphones and they range from 32ohm all the way upto 48ohm, then there are headphones with 100mW etc. I don't know much about these values in terms of headphones and how good a smartphone can support, in terms of current/impedence.
Any ideas how this actually works? Does the sound get lost if the phone doesn't support higher amounts of current.
I've studied the big thread about Volume Boost of headphones...
Is there anything around about non-headphones volume boost. My V10 is not very loud compared to my Note 4 with Viper ...
Thanks!
I haven't looked into the physical components, really, but if the dedicated ESS DAC with the amp act as any other dedicated components I'm familiar with, then you would have to physically change the wiring route to the speakers. Right now it's headphone only because the amp is directly connected to the output jack. The first issue is software-based, but the second (with the speakers) relates to hardware.
Again, I haven't really checked, so someone correct me if I'm wrong.
Some of you may agree but some may disagree. The audio output of the 3.5mm headphone jack is far to quiet.
A cheap and easy solution to this is I bought the USB-C to 3.5mm DAC from HTC. Join the HTC club and it was £5.95 with free next day delivery.
Much louder and very good quality. Can't find any specification on what BIT the DAC is and I don't have the tools to measure it but its far better than the build in 3.5mm jack.

I've got tinnitus in my right ear from constantly having a headphone in it for a number of years. I used to always listen on the loudest volume. With the xperia xz you can have active noise cancelling headphones, I can warmly recommend the nc31em in ear, I bought a pair for 15 bucks and it uses the processor of the phone so you don't have to carry a big dongle. Now I can listen at half volume and still hear everything better than I did before!
I received a Griffin iTrip Clip Bluetooth headphone adapter so I could be wire free from my phone and found this improved the loudness and remained good quality audio. You may get a bit of breakage occasionally if multitasking but for £14 from Amazon, it's a cracking piece of kit!
Fantastic solution
I have followed the steps of signing up for HTC Club, and ordering the adapter straight away. It really came next day with no extra charge for delivery. And oh boy, the sound is amazing! I am bit of geek when it comes to headphones, so i have a multiple different types. The difference between using the audio jack output of the phone and using the usb c adapter is NIGHT and DAY. Not only loudness is incomparable higher, the pure quality of the sound is improved in every way. I do not believe that there is DAC hidden in the adapter, as it is quite small and low priced. What makes difference in my opinion is the additional power phone can send to the headphones by using the USB C out. Difference is so big, that this workaround can be seen as hidden features to extent, as Sony has not said a thing about using your USB C out for audio. Now I truly understand why the removal of headphone jack make sense as even phones with not the best DAC and AMP can produce great sound thanks to power of USB C.
In case of Sony Xperia XZ however, it looks as DAC is of a top- notch quality(it officially supports Hi-Res codecs after all) but the AMP is criminally under-powered and so combined with Sony obeying EU regulations for safe listening volume converts to quality sound but on quiet side. But thanks to this adapter the DAC is no longer tied to volume level set by headphone jack.
Everyone who owns this phone must buy this, especially considering the low price of the adapter. You need hear it to believe it.

I was on another trip recently and one scheduled for next week. Indeed the sound out of the headphone jack is extremely low so I ordered one of these gadgets and will arrive on Friday. The success from others is what I expect to gain and will report back

Its not working for me too...using the xaomi dongle
Just asking is they a way of updating the dongle without having a htc device I've installed the audio usb jack toolkit from htc but nothing seems to happen
Thanks
Thank you so much for this. The low earphone volume was driving me mad. So after reading this, I bought the same thing from HTC and it works fantastically and sounds amazing now.
Is is working also on oreo latest update?

Yes works fine with Oreo.
Two kinds of USBC to 3.5mm Adapters, beware.
Just so folks know, there are two types of USB-C 3.5mm adapters out there - Digital and Analog.
All decent phones should support the Digital adapters, since they are just USB Audio Class devices made small. You could also plug them into a PC. Because they contain the DAC and amplifier, they will be spendy.
However, the $2 Passive adapters have no DAC in them. They trigger a special mode of the phone that basically puts the USB-C jack into an analog 3.5mm mode and the rest is just plastic and metal. The DAC is in the phone. The phone has to specifically support this mode, and will likely indicate USB-C Analog Accessory Mode in their specifications. Xperia XZ Premium does NOT support this mode, and never will - it has to be built into the hardware.
Just sayin.

how come some people heard a huge difference in audio quality?

Because people are trying different USB Audio headphones. Sony is not in control of their quality or amplification since the DAC and amp are in the headphones. For those using different 3.5mm headsets, their quality varies greatly. Sony expects folks to buy theirs, preferably with their active noise canceling that they wrote software for. It works well but as stated, they are not very loud.

ok so I have an audio system in my car, and volume in headphones gets super low compared to CD (I know CD quality is the best you can get i think) but still its VERY very low compared to it, in aux on 13db I get same loudness as 7db in CD, which means I have to turn it on almost twice as much as a cd to hear same loudness, (why dont I simply turn my audio more than usual on a cd?) because I like listening to very loud music and I some times get to 23db on a cd and its very loud and on aux i must reach at least 40db to get close to being as loud but my audio system only supports up to 30db so I am getting aux loudness of 15-16db compared to CD.
will the usb 3.0 to AUX DAC help me get louder volume?
I got my LG V30 this week but I can't tell the difference between dac on or off. I've used Tidal on Hifi mode, streaming a 24/192 from the NAS using Shure se846 earbuds. When I toggle DAC on/off and don't look, I can't honestly tell the difference even at high volume. I would expect the dac on to be louder?
It sounds nice but compared it to my old Galaxy S7 no major difference.
Can you audibly tell when dac is on or off? Is there any way to get diagnostics or geek stats to see if something is wrong?

Same here, LG V30plus. To me, with or without DAC, almost same quality, using tidal hifi, lg music player, spotify. I can say that on S7 the bass was more present, using the right setup and a pair of Soundmagic E10. I am little bit disappointed but maybe we are rookies in using the right setup or headphones. I have the BO-s that were in the box with the phone. and the volume is way too weak.
I've got my V30 for a week now. First time I listened with pretty decent (low impedance) in-ears I had the same impression as you. DAC on sounded even worse than off. Second time I did an A/B comparison against an Oppo find 7 which is no slouch in sound output, and everything was fine. DAC on was better then off and my V30 was on par with the Oppo. Today I was in the mood for some music, and DAC on is again bad.
I have no idea what is going on, besides a bad manufactured V30. Or being a rookie
@gjvdkamp
Shure SE846 has a 9 Ohm impedance only. To trigger the Dac you have to use a >50 ohm one.
@all
You can easy check the Dac with
Hi-Fi Status (LG) app. This app is currently for free on Google Store.

Hi Fi Dac works with < 50ohm device, the High Impedance mode needs > 50ohm.
You can trigger the Quad Dac in the quick menu or hold the icon for more options.
The Hi-Fi DAC is not amperage dependent. It's either enabled or off when you insert a headset or device into the 3.5 jack. Of course, first time, you will have to activate the Hi-Fi DAC on the main drop down menu, and you can always turn it on or off when a headset is connected. Amp section should automatically determine what type of amperage device is connected to the V30 and adjust high impedance mode accordingly. Or, you can force a higher impedance mode with an inline connector if you prefer.
Hi All
I listen to music in car a lot streaming from Spotify, and have been using a standard AUX connector on a stock radio in a Corolla 2011.
Before the Realme GT2 Pro, I have been using a Lumia 650 and the sound was amazing. Balanced, loud and not lacking in any area. My volume settings were Max on the lumia, and about 40 out of 60 (max) on car radio (and this was already very loud). Before Lumia, I used Galaxy S7 and while the sound quality was slightly worse than Lumia, the loudness was still OK.
I borrowed an OEM Samsung USB C to AUX connector and found out that the sound from GT2 Pro is too quiet. With GT2 Pro volume at Max and my car volume at Max (50) it was much quieter, I could hear noticable distortion, and the sound profile seemed flat. Almost as if there was no pre-amp in the GT2 Pro.
I have a suspicion this is not an isolated issue to Realme, but to all phones that pass audio through USB-C.
My question is:
What would be the best way to get same or better quality of audio as any phone with a pre-amp/integrated audio chip out of Realme?
I am considering:
- Do I need a different USB C to AUX adapter? The adapter tested was original Samsung USB-C to 3.5mm, not a knock-off.
- An aux-to-bluetooth kit, however bluetooth streaming is generally LoFI
- A USB powered DAC? Ideally one that can take bitstreaming audio from phone via USB C and pass into AUX lineout
- Replacing stock radio. I really do not wanna go this route as I feel it is redundant, because my cheap a** Lumia sounds superb on it, and Galaxy S7 was good too.
- Some kind of jerry-rigging offline Lumia to handle audio streamed from GT2 Pro. I have no clue how this would work
Any suggestions are most welcome!
It's due to a recent law that limits the sound level on phones and accessories.
I bought the apple 3.5mm usb c dongle and tried it on my car and same story it's very quiet, have to crank to the max.
The European version dongle have limited voltage compared to the US version and Android also has a limit on the volume but you can change if the phone is rooted.

Hmm.. I read that apple usb-c adapters don't play nice with android phones and are quiet by default.
I've tested a Samsung OEM adapter. As a band-aid solution, I am hotspoting wifi from Realme to Lumia.
EDIT: Here are the findings so far:
1. Tried installing Viper4Android with no avail. Driver not found loop. Maybe someone can figure out a method that works.
2. Confirmed the sound is much louder when Samsung adapter is used with a Galaxy S10+ as compared to Realme
3. Dolby Atmos EQ in Realme actually worsens the quality
4. The volume can be boosted with a shell command, but only with root and after the adapter is plugged, since it acts as external audio device. Tasker or other app can be set to run the command on headphone adapter plugged in
The command is:
su -c "tinymix -D 1 2 100"
Where the "100" is the gain
To display all adjustable variables:
su -c "tinymix -D 1 2 -a"
The default value for Samsung adapter is 83, where 84 is equal to 0dB gain. Maximum range setting is 108, which would be equivalent to +24dB gain.
