Attempting to optimize headphone sound

I would like to use my Evo as a MP3 player when I exercise like I used to with my old Sony Ericssons and my iPhones, but the sound quality compared to just about every other phone or mp3 player I have ever owned is not very good.
Right now I am running Ava's Z3 ROM. It's supposed to have some audio enhancements. I also bought PowerAmp and use DSP Manager. I configure and tweak as much as I can. I would like the sound to be a bit louder through the headphones. The phone speaker and in-call volume are fine.
As far as I am aware there is no way whatsoever on this planet that the headphone volume can be increased, even if just a small amount, to the HTC Evo.
So beyond what I have done already, does anyone have any more ideas on how to get better sounding and perhaps louder music without actually having to change the mp3 itself?
Thanks!

Change your kernel.

There was just a thread about this here:

I listen to music on mine all day long in a pretty loud environment (well, a lot of fan noise anyway) with no issues at about 3/4 volume . . . so I think the problem some people are having are with the earbuds/headphones they are using. Maybe try some with a lower impedance.

I read that some kernals can up the speaker volume and in-call volume but don't have much effect on media stuff, especially when it comes to headphones.
Is there a specific kernal you know of that boosts headphone volume?
Thanks!

Sorry I did a search, but just in the Q&A forum.
Some people are happy with the volume of the phone. I'm just used to things being a bit louder. When I'm running I hate hearing the sound of my feet and the wind etc..etc. The headphones I use have an impedance of 16. Is that too much?

Hissing noise in left ear when playing music through headphones

Anyone experiencing a hissing noise in the left ear when playing music with headphones? It's more obvious in some songs and its really irritating once you've noticed it.
Seems to be the same problem the G2 has: THAT Kitkat Audio Bug - Hissing/Crackling. - xda-developers

Yes, me to. It's very anoying. Hope it will be sorted out otherwise I return the G3 to shop

I have the same problem here. only left earphone having hiss noise during a music play or anything.
Do you think this can be fixed by a software update or should we refund the device?

I have a G2 running the lastest euro open rom and the issue is still there. Nothing has been fixed! Lets face it... They either don't want to or don't know how to fix it...

Hello
While I do not get a hiss I am getting distortion from the LG G3 in the left on earphone - I have found that it happens on the earbuds you get with it along with my Sennheiser, both have them inline volume controls. My Sony earbuds do not have the inline volume control and I do not get that distortion. All earbuds testing on other devices and working perfect. You can hear the distortion in say low volume parts of say the Man of Steel soundtrack.
Anyone else have this issue with distortion in the left?
Thanks.

For people who are "not sure" if they have this issue: play some music with rhythmic bassline, then go to Settings --> Accessibility ---> in hearing section move the "balance" slider to the right. Now you should hear the distortion in its clear form in the left phone.

... would be interesting to see how many have this - I would pop round a few shops this weekend and try out some demo units to see if they also have the issue - however I am moving so no time - Would like to know if everyone with the G3 has the issue or some.
Its not something you have to listen very hard to notice - something with a bit of bass effect - I notice it on Man of Steel soundtrack, 1m 12s in on the track DNA.
By the way is the same if you use in inbuilt music player or my preferred player PowerAmp, of course all effects are off. The media files themselves are flacs which I use in testing audio equipment, so I know the files themselves are perfect.

I have this too. But it also seems very picky about which AUX-cable to use. Ive tried 5 different wich I know all works well.. tested them both with another phone and my Nexus 7. With 3 of them the phone doesnt even recognize its plugged in, the sound continues to play though the phones speakers. With the fourth one I get sound but very noisy and when i rotate and wiggle the cable it gets more noisy and static. With the fifth cable I dont get any of that but the left channel is still a bit noisy at certain parts in the songs, just like you describe in this thread.
Do you think all this is related to the same problem or have I also gotten a phone with a bad jack?

Hey Dyln
You have come to the same conclusion I have come to. Really not sure whether to ask for a replacement and find I get the same experience (alot of hassle for nothing) - Just find its really funny about what headphones you use. I am not liking that my £50 Sennheiser earbuds for gym do not sound as good as my other devices - Is that a batch issue on the hardware side?, is it a software issue (like G2)? God knows !... just annoying as its otherwise a great phone.
Christopher.

Hi I have the same issue with a pair of Shure SE-846 (9 Ohm). Very annoying. Hope this will be fixes soon or I have to get an in-line resistor to increase the impedance. There is (almost) no noise with headphones above 32 Ohm.

I don't have hissing on mine, using the stock Quadbeats and iPhone5 headphones. I have the F400K Korean model. (I am familiar with the hiss as my old G2 had it (was fixed when I was using one of the Cloudy custom rom though).

Distortion and feedback in between songs playing in car with 3.5mm jack
I've just posted over here which is I reckon a related issue involving the 3.5mm jack....
http://forum.xda-developers.com/lg-g3/help/aux-cable-problem-t2802719
At the risk of repeating myself I'll just copy and paste in here too...
"I have a similar issue with the 3.5mm audio jack cable in the car.
Although i have tried a couple of cables and they do produce audio out of the speakers, I have a nasty problem whenever there is a gap between tracks, or when listening to radio if I pause it for more than 1 second.
It's as if the LG is cutting the power to the aux cable, so that when the music is restarted, or more annoyingly of all after EVERY song when played straight from the device, there is a nasty distorted feedback coming from the left speaker.....
Surely this is related to what the folks are saying over here...
http://forum.xda-developers.com/lg-g...music-t2804065
It never happened in my car with my Galaxy S4 or my Galaxy Note before that.
I'm seriously considering returning the handset as this noise is just not bearable - it's getting near a deal breaker for me.
edit: should have mentioned it also happens when an incoming call ends, the music cuts back in with a big old distortion/feedback."

I am also having the same issue with my unit. Do you guys think that an update can fix this? I had my G3 replaced for having a damaged screen. I don't want to return it to the retailer again because of the buzzing sound.

It's good to know that there will likely be an easy fix. Even if that app has some compatibility issues, I'm sure a G3 version would come out.

LG G3 Hiss noise on left headphone
I did quite research on this issue.
Here is what I did:
Tried with 7 different high end - low end headphones. All having same issue on left headphone
My friend has the same phone, he is having the same issue
Went to Retail and tested 2 different phones, both having the same issue.
Tried with different songs, but the best songs you can listen to understand the noise is solo piano songs.
Try to listen this song: Ludovico Einaudi - I Giorni
If anyone has bluetooth headphone, I would like to see the test result. So we can understand if this is hardware or a software issue.
If bluetooth fails, It could be software otherwise most likely a hardware issue.

I thought this was a KitKat issue... so returning your G3 won't do any good. I experience this also. I'm not sure why Google hasn't made a fix for this yet.

Brilliant, thanks Online111; was meaning to pop round some retail shops to test out other G3's. Looks like it is a personal choose then if you can bear it or not. Was very nearly going to get a swap out.

[Q] Hissing sound in earphones

I just received my G3 (the European 855 version) today and wanted to listen to some music from Google Play Music All Access. There is a terrible hiss/crackling sound, especially in the left ear and it's with earphones that (still) sounds fine on my old SGS3. I've tried with 3 different pairs of earphones and it's the same with all of them.
Does anybody else got problems with hissing/crackling sounds from the G3?

I solved this myself - the problem is "only" there if I'm using ART, after going back to Dalvik the problem is gone again.

Dont have this problem with my D855. Not with v10a or e. Used this phone with headphones/speakers about 8h/day since release.
Im using ART.

Switching back to Dalvik didn't solve it After a reboot the sound is fine but after a while the hiss starts, especially in the left ear. Nobody else got this problem? I'm on v10e with a D855 32GB
UPDATE: I just connected my Fiio and with that to amplify the sound the hiss goes away but as soon as I remove the Fiio the hiss is back again.

it's a problem.
But it depends what kind of earphones i use, with my sennheiser MOMENTUM it's perfect.

That seems to point to an impedance issue. It is not in every phone because I use very low impedance IEMs and do not hear it. I have also read reports of it just going away on its own.

This is a kitkat bug that was uncovered last year.

That doesn't explain why some G3 owners got the problem and others don't as we're all on 4.4.2

Except that I have used a variety of different impedance earphones with mine and have never experienced any hiss. I think higher impedance can mask it if it is present but doesn't fix the root cause.

i dont have this problem..im using the earbuds that came with the s4

Hi, Is this problem solved in lolipop update?Thanks

I'm having this same problem with my D855 that I bought today.
It sounds like a loud hissing noise (like interference) and only seems to come out of the left ear piece, it's not noticeable when the music gets busy but during the quieter parts or where only one instrument is playing, it sounds horrible.
I've tried my Monster Turbine Pro Coppers and the bundled earphones, both produce the noise. It's also very apparent at different volume levels.
Updating from KitKat (4.4) to Lollipop (5..0) didn't help, as the problem is still there.
Looks like I'll be returning this phone already as I use my phone to listen to music a lot. It's a shame that such a fundamental problem should ruin what is otherwise a really nice phone. Ah well.

This problem has been discussed in many threads and i think its a software problem.
Reasons why i think it's not hardware relsted:
-The g2 has a similar issue but only after you patch kitkat on it.
-on my g3 and many others the hissing disapears after you make a call (with no headphones pluged in) until you reboot the system.
This simple bugfix works for me but it's a pain in the ass and i hope somebody finds a way to fix it for good
Ps.
Stock Lollipop and cm 12 both do have the problem

Increase volume without root?(Maybe just a sound issue in general?)

I just got a new g4 this morning and I must say.... The volume on the speaker is incredibly disappointing.
Is there a way to increase the volume without rooting the phone?

i don't know the answer, sorry. but, do you mean the speaker volume when on a call or the rear speaker? i find the caller speaker a bit low

Sorry, the rear speaker.
It is exceptionally quiet compared to almost every other phone I can remember using.

mines quite loud, well maybe not loud loud, but louder than my galaxy S4

Here's an example of the audio quality. I recorded my Note 3 and G4 on my Yeti Mic(turned the sensitivity up so you can hear both clearly)

Question Pixel 6 Pro Audio Crackle

Is anyone else getting an audio crackle when tapping the mic icon for voice typing? I remember this was fixed through software on my Pixel 2xl years back. It basically pops, sounds like it's clipping. VERY annoying.

Great...
Google still can't provide proper speaker and mic since Nexus 4. How many years has it been now they been providing worst audio and mic performance?

Did a factory reset to see. The microphone in google own messaging app didn't seem to crackle, but through Textra it did.

No crackle for me even on max volume.
What I did notice is that the stereo speaks are imbalanced in terms of volume. The selfie camera side speaker sounds way more "muted" than the charger side speaker.

Agreed. MAYBE the volume levels are the same on both sides, but the selfie side definitely SOUNDS different. I also dislike the way notifications sound. It sounds like it's coming from the back of the phone going away from me, making it sound like it's coming from a different phone a couple feet away from me.

Audio balance has always been an issue with Pixel phones, although they made a change to the series 5 which boosted the ear piece one was called adpative sound, maybe it works as well for 6

Have you actually got the phone? All I've seen you do is comment after comment about how rubbish it is but nothing from you directly?
If you hate it so much don't get one.

No crackle for me. I use the mic often and play podcasts through the speakers of the day. The speakers are good, clear and can get loud if ineed them to.

The popping/crackling sound is happening on my pixel 6 non-pro model. If sound is playing and I either type or move around to different screens this happens. Looks like I am returning it.

So far I've only noticed pixel 6 pro speakers crackling playing genshin impact, easily heard on the main menu, but so far only noticed it in that specific title. Not while playing music or other games. So I'm hoping it's software related and I don't have defective hardware.

No crackle so far, just rocken Music.

Can you do a video for us, showcasing when this happens exactly and what kind of noise gets created?

Too late, returned the phone and earbuds. Between this, the lousy fingerprint reader and the phone randomly calling people, I am done.

I dont get how people get so many issues with phones lol... I've never had problems with any of my phones and I've had many...
My FP works 100% of the time, it is just a bit slower than the rest, but even then, just barely. I have a S21 Ultra in front of me right now and after testing both, I can definitely say that the S21 Ultra is a bit faster, the Pixel one is actually more accurate. I would prefer to have it in the back like previous models.
Having said that, if I did have those issues you described I would return it too.

I feel like it's a software thing, honestly. Because when i first setup myh device before I downloaded all the updates, there wasn't any audtio crackle at high/max volume. After I downloaded the updates, it's there slightly.

I don't have crackling or distortion, but I'm getting a good deal of sibilance from both speakers. Here is a definition of sibilance.
Sibilance
I listen to a lot of YouTube podcasts and videos and this is driving me crazy. I wanted to see if anyone else is having this problem before I see about returning the phone. Adaptive sound and balance control makes no difference.

I have a 6 Pro and have noticed crackling from bottom speaker since purchase when turning speaker on during phone calls. For me I otherwise really like the phone. I will be doing a repair or exchange once more phones become available.

I got my replacement brand new 6 pro, and now this one has distorted and crackling sound from the earpiece speaker. When i press the middle part of the screen anywhere.

I have turned off the adaptive audio, and I can hear the balance over blutooth changing. With one headset when listening to a mono podcast, you can hear the audio balance shifting randomly around.
With another bluetooth headset (my hearing aids), the balance starts out biased to the right, but the longer you listen the more it drifts to the left. Stopping and starting the audio stream immediately corrects it.
What is going on -- I have had every OnePlus Pro model since the 6, never had any issue like this.
Anyone have anything similar and or no how to fix? It is so annoying....
