Portable Audio Amplifier - Asus Eee Pad Transformer Prime

Has anyone use the TF201 on an airplane with closed, but not noise-cancelling headphones?
I've found that it's not possible to get the volume up loud enough on my Audio Technica ATH-M50 headphones to be able to hear dialog in movies. The headphones are great, but even with a closed design they are just too quiet at the loudest volume to really hear well on an airplane.
Has anyone used a portable amp with the prime that you would recommend? I've done a quick search and it seems like a lot of amps need a digital input. I'd imagine that I'd just need a simpler analog amp that takes a 3.5mm input. I'm looking for something cheap to just help on an airplane. Any recommendations? The cheaper the better.

Check out of the fiio e line. They have some portable amps that use the 3.5mm connection. I have a fiio e6 and i like it

Have you used it on an airplane and does it seem to give you enough of a boost to overcome the background noise? I think I got confused when I saw the fiio amps because they photos show them hooked up with a custom connection to an iPhone for example, but now I see they just take a 3.5mm input.
And they aren't too expensive so I might just try it out.

I have the same model headphones.. a Prime.. a Fiio amp. The cheapest one... And they work great! Makes them much louder

using windows phone 7 on my hd2 you could increase these volumes from the rom. Is there nothing like this in android?

Don't know if you tried any of the apps on the play store. I use volume + app. Works great. Lets you go above the stock volume levels for both the internal speakers and headphones. There are other apps out there to boost volume as well.

Of course.. but you need to be running a rooted/custom ROM. You can usually mess with the audio configuration files in the /etc folder for whatever audio amplifier chip is in the device.

I use an app from the play store called "equalizer" to accomplish what you're looking to do, works perfect:

Just do a custom setting, and instead of doing a typical EQ curve, just boost every slider by the same amount and this will give you a volume boost.

Best audio boost method?

Anyone had any success with an app to boost the speaker volume of the NC?
I read that Audio Boost 2 doesn't alter speaker volume much. I have not tried anything yet, but would any audio app with an EQ function allow boosting all freqs. work? I know that there is a chance of overdriving the speaker, but I want to try to get this "fixed". The speaker volume is the single most annoying issue with my NC. Mainly with sources with audio tracks that are recorded at low level.
Any help is appreciated.
Thanks,

Obviously, no-one did much. The worst part is NC's CM7 devs don't see it as a problem.
However, if you could talk dalingrin into looking into the issue (I myself failed to entice him to do anything), then there are some chances with his forthcoming new audio pipeline/ALSA commits.
As of now, when on CM7, you may try to play with DSP Manager's equalizer. Doesn't do much, agreed.
-------------------
fineoils.blogspot.com <<-there's not many answers here, but there's plenty of questions, sure
Only luck I'm having is headphones. Its really bad when the speaker is pushed up against the back of my case. Volume is horrible.
Use earphones will be the best bet for the time being.. Unless is CM7 got vol boost...
you can try poweramp, it has audio boost eq
yes its work withe me
Played around with Poweramp. Adjusted EQ midrange boost, keeping bass low & boosted Preamp setting & have determined that the speaker may just suck! Unless Poweramp EQ is adding distortion when the levels are boosted, the speaker can't handle much volume before breaking up. There may be no hope that the NC will ever have decent volume.
I find the volume on many sources to be barely adequate for personal listening in a quiet room, but for showing another person a video in a not so quiet environment, it is barely audible. I have also noted that the audio quality from the headphone jack is really poor when compared to any decent MP3 player. Looks like B&N saved $$$ on the audio section in order to bring us the nice screen & other quality hardware. I think that I am OK with this, but it would be nice to have it ALL!
Cheers,
kev
P. S. This may end my search for an internal solution to the volume level. Probably keep experimenting with small phone jack based amplified speakers.
The volume seems fine to me.
Hopefully we can have a stable Bluetooth stack working, so that we can pipe to audio to BT Speakers...
I really think the physical speaker is just crap. At the end of the day, you can't fix crap.

That's the conclusion that I am coming to. Seems B&N found it necessary to keep the output level low so the speaker doesn't break up. Be fun to remove it & connect another more efficient one that can handle more power. I think I will continue to experiment with the small headphone connected powered speakers.

I would be interested in seeing how much it would cost to solder in a "good" speaker.. I would think there would be a bit more space to squeeze in a decent speaker or possibly two?
First thing I thought of before I even bought my nook was what speaker was I going to buy for it! When I saw it in stores, I knew there was no way that speaker was going to do anything, and it made me wonder why it's even there. Considering that it's not loud enough for audio books really and mp3's would just play way too low, I think they should have just left it out and added 2 aux ports! Okay, that might not be realistic, but still!
I've opted for a portable iHome speaker from Wal-mart(it's the one that is a round cylinder and if you buy two you can have them hook to each other) for only $20 and should be getting it today. Unfortunately my PSP speakers blew out or that would be perfect for the nook since those things were loud enough to start a party.
Try my mumusicon it has got a sub increase function and that increased my nc's speaker volume more than 40 percent without causing distortion

Well, I dnlded Mymusicon & don't see any way to adjust the volume???
Edit: OK, tapped the album art screen & got another menu. Under "volume" there is a "sub" adj. that increases volume some.
I use DSP Manager to just raise all the EQ levels all the way up. It's pretty loud now.
stoopid but helpful
With the CN facing you in landscape, hold it up with your left hand. Put your right hand palm flat on the back of the device, gradually moving your palm to the right. You find a 'sweet spot' where the speaker is amplified about 50% by reflecting towards you off your palm.
Play around a little & you learn if your hand should be half way out from under the CN at the right side for loudest clearest sound (what sounds best to me) or palm cupped or flat.
An easy DIY aplifier would be a piece of flat plastic (like cut from milk bottle) adhered with a tiny bit of velcro at the 'sweet spot'. Could be detatched for travel, not need bulky external speakers, yet deliver noticably louder sound.

Using the sgs2 with a high-end headphone.

I've been considering for a while to buy a good headphones and I've decided to buy an audio technica ath-m50. The only thing that is bothering me is the yamaha audio chip. If I buy those headphones, I'll be using them most of the time on my sgs2.
Will the yamaha chip make the ath-m50 sound like a cheap low-end headphone?
If you happen to own an ath-m50 I wold really appreciate it if you could measure the hollow of the earth cups, diagonally and horizontally maybe. I've read that people with large ears may find them uncomfortable. The length of my ears are just below 7cm(I don't care, they are small, my mum told me that)
I've read supercurio's analysis of the audio chip but my question still remains.
Waiting eagerly for any response.
Get an iPod nano- excellent sound quality and a great price. I hate using my GSII for music though Poweramp is a great app

Well, if you really want to use a pair of high end headphones with the galaxy sII, get a portable amp like i did. I got a fiio e7, and it powers the ath-m50just fine. Listening to them straight out of the GSII audio jack wont let them utilise their full power. And dont get an iPod if you want really high quality audio. :-/ (Just a suggestion )

I have bought that app even though I rarely use it because for me the s2 is loud enough. I'm more worried about the quality of the sound.

It simple buddy take your handset into a store that sells these headsets and test the thing in house.
From there your should be able to make up your mind.

I've thought of this, the only problem is finding a store that sells the audio technica ath-m50. I live in London I'm sure there is plenty of stores.
However this would not be much help because I'm not very experienced with high end headphones, so probably almost anything will sound good to me.
If you want to listen to boom boom music with heavy bass then the SGS2 is inadequate .Expensive headphones are not going to do that much .
However as a user who does not have any boom boom music i find stock player headphones or slightly upmarket low end Sennheiser headphones fine .
Power Amp for me strangely lowers sound output level .

I've the same experience as JJEgan with Power Amp. It seems to boost dynamic range at the sacrifice of overall volume.
For getting the best out of high-end headphones, you could always try Neutron Music Player from Android Market. It claims to use its own "32-bit audio music rendering core", although it's debatable whether this makes a difference, given that uncompressed CDs only have 16-bits per sample. People seem to like it, though.
Just recently I noticed something when listening to music using Poweramp with a headphone.
When you click on something such as the app drawer, the volume of the music that you are listening to increases for fraction of a second then it goes back to normal.
It can be very annoying when you are using the phone while listening.

Tried Neutron at the weekend, and these old ears couldn't see - OK, hear - what the fuss is about. No difference from Poweramp with a very unscientific ABX on my Sennheiser IE8s.
Definitely the worst UI I've seen on any music player though - so hideous that it should win awards.

Senn HD25-1s and Ety ER4-Ps both sound fine straight out of the headphone socket.
Using poweramp, without any eq or tone control tweaks, just ~30% crossfeed.
I read all the reports of crappy audio on the GS2, so when I got mine and tried it I was very pleasantly suprised.
Whereabouts in Poweramp settings is crossfeed...Didn't realise Poweramp supported it ?

Anyone using external amplifier throught Headphone Out?

as per title..anyone? mean to say PORTABLE.
I've stopped using gs2 to listen to music long time as the volume is too low and also finding harder to drive my headphones to full. Just only yesterday, my iriver broke and in the market for new player. Thinking whether should be better off with just getting Fiio E6.
yes, we do lack line out through usb (very hopeful that it'll be put on ICS) and the only way to connect is through headphone out which is already amplified.
impressions pls. Thanks.

volume is too low???? either your ears or s2 is done!!!!
think it's both. But yes normally I listen to a high level of volume and gs2 is the one of the lowest sounding device (ie through headphone out) i've ever owned. Not made for each other and made worst by owning couple of higher impedance headphones.
i have been using a FiiO E5 from when i had a n900, i think the volume is too low on the s2 aswell, i think you can get them for less than 20quid now, deffo worth it imo
thanks for that. I'm almost set my heart to buy one of these for later to be paired with sansa clip+ or similar. Probably will be cheaper and better than cowon's or sony x's. It's just curious what will be the effect on sound which is already amplified as HO in gs2.
Try Voodoo Louder from the Market for a 6dB increase, or the app in my sig for more than that. I use Brainwavz M3's with this app & find I only need to have volume at around 30% even in noisy environments (public transport, walking around town).
I've not found the S2 volume to be too bad, but I've used both one of the small "pop up" speakers, as well as a full blown amp, and a car headphone in socket - all absolutely fine.
you've tried Equalizer?, is in the market, is very good. regarding your original question, i use mine with logitech LB21, and it's sounds amazing.
Regards.
with Poweramp I think the sound is louder than the music original application, you can find it on the market
yes i use the E6 - it works fine and the quality is good.
Do not use any of the EQ's etc as suggested here to get it louder. The samsung internal amp can only go so loud without distorting - all u are doing with software boosts is dynamically effecting the music you are listening to. Somewhat like the radio does. It makes all of the instruments in the track as loud as each other by compressing the loudest sounds and lifting the volume of the lower ones. If you really want to get a louder performance from your phone use different headphones - that run on less ohms or use an external portable amp like any of Eii's series.
that's a very good explanation. I've also tried with low impedance headphones but still lacks the "punch". My bad as in OP I used the wrong word "loud" instead of "punch".
so what's the effect of E6 on already amplified Headphone out? just to amplify few dbs on all spectrums??
Rockbox on [email protected] and [email protected] with Voodoo [email protected] did improve the overall sound. Also maybe in that time, my ears started to adjust with the sound coming off GS2. Found similar thread here where ppl's had good experience with amplifer. Ordered Fiio E11 and will post impressions arrive.

Audio - Output Level

I've got a couple of requests, both audio related. Hoping ROM and/or kernel developers might be able to help out...
1. A global gain setting/boost for the headphone jack. For those that use the headphone jack with, say, an Aux In to a car stereo, you really have to crank the stereo to get decent volume. It's probably a good 20-25% lower output than my iPhone 4. The Play Store boost options are unreliable and only work for apps that don't include their own built-in EQ.
2. Toggle to disable the LG feature that turns the volume down automatically "to save your ears" when you plug something into the jac. It's a good feature for headphone users, but a real annoyance for those using Aux In on another device. Plug in, crank the LGOG, crank the stereo and you've got a listenable signal.
Thanks.

Again, the booster apps only work for apps that don't include their own EQ. So it's fine for Pandora but not for, say, Subsonic.
Best way to do this would be with a system-level tweak. I had a Nook Color and they had extremely low audio levels. A dev added this feature and all worked great.
Clearly I'm not alone in being annoyed by this issue.

In the interim you could just not use subsonic and use a simpler music app...

PowerAmp provides a small boost, which makes the puny LG headset just loud enough. Sennheiser speakers generally seem to be louder, though most of them have 32ohms impedance, 16ohms should be louder, theoretically. I like oldskool headphones without silicone plugs, i don´t think the new ones will last one decade like my Sennheiser MX550. I just bough MX400 MS for less than 10 Euros, looking cheaper than the MX550s, they provide the same sound quality and volume.
The LGs headset plug is Apple compatible, without an adapter to switch mic & GND connectors, Samsung and Sony stuff won´t work. Nokia´s needs the adapter to play music w/o distortion, but control buttons will never work.
