[Q] Audio Quality over Bluetooth? - Sprint HTC EVO 4G LTE

Hey all,
I just switched over to the Evo 4G LTE from my trusty old Photon. In my experience, the audio over bluetooth is much worse in terms of clarity. I had no problems pairing with my car's bluetooth system, but I can't say how poor my calls have been in comparison to my old photon, and even my AT&T iPhone.
What is everyone else's experience?

htc does sometimes slack with their bluetooth stacks but I don't really have any experience with it through a car stereos. Have you noticed any difference in call quality using the phone normally?

Well I've played music in my car and it sounds excellent. Calls sound ok, i may say not the best but its not bad quality. I even have a Bluetooth keyboard with touchpad at the same time and no issues at all.

Much better than the garbage they had for sense 3.x, but still not as good as the bt in cyanogenmod

My experience is just in regular phone calls. I've used the Photon for the past year. I won't say it's reception is better, but it definitely sounds better over BT than the Evo 4g LTE. Calls in the car are quite important to me, so, that could be a dealbreaker.

BT calls on my visor mounted speaker are clear as can be...and I wear hearing aids so when sound quality sucks, I know it quickly.

Something is wrong with bluetooth!!
Coming from the og evo never had an issue with the bluetooth in the car or any other device I connect to now with the lte evo it's choppy for the first 30 sec to a min of connection and then during playback it randomly chops almost as if it was buffering or something. Any ideas?

No issue here. Connected to SYNC in my car. Music, nav voice, and calls are clear. Imo better quality than the 3vo. Even noticed beats works for nav and music. Very happy. Less issues with voice commands via sync too

I'm getting this too and it's very frustrating. Anyone else?

No issues with BT
One thing that greatly improves the BT sound.....turn the phone's BT volume up about 1/2 way.... It does sound sub-par when I have it up too high.

Full firmware update + new base fixed my problem. I believe it was the firmware, though.

[Q] Bluetooth Audio Quality

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.

Issue with calls over bluetooth

Hey everyone,
So I usually use my cars built-in Bluetooth system for calls as well as music. Since I switched to the GSIII i have had terrible phone audio over my cars speakers. The audio will be perfectly clear for a couple seconds then fade to almost nothing for another 2, then clear again, this just keeps going on and on. I end up missing half of what was said. The music audio, however, has been perfect, better quality than my old phone even.
I never had any issues with my old Atrix, the audio was always consistent, same car and settings.
To those who managed to get the phone early like me, how has your experience been with bluetooth phone calls?
I 've been using it in the car since the past week and it has been pretty smooth for me. The audio and signal are both perfect.

BT and WiFI Issues

Hey guys, I'm getting tired of my IP5 and was on the fence between the OX+ and the LG O G phones.
I prefer the size and build quality of the One X+ and the Camera and Google Now ect, but I like the LG's skins and UI over Sense.
But I've also read that the One X has BT audio issues in certain cars, since I have BT in my car I would want it to work.
So what's the verdict?
Yeah I know this is the HTC side of the forum, but you can tell me, its ok.
Thanks
I tested BT on my HTC One X+ and it works. It works as well for file transfers as i have done some test for review which i am writing at the moment.
WiFi works great.I tested in the trains, home and some 'free wifi' ones without any problem.
It terms of skin. I can't help you as is personal preference based on personal usability requiremnts (in my case .. i prefer Sense).
I bought HTC One X+ (as LG OPt. G was one of the first which i exlcuded from my selection )

I've probably have tried at least 4 HOX+ phones, all with the same Bluetooth problem. Read through this http://forum.xda-developers.com/showthread.php?t=2001204 to make an informed decision. In short, File transfers, music sound fine. Bluetooth voices on phone calls are really bad, except with a select few bluetooth devices such as the Blueant Q2. Personally, calls on my car's bluetooth were really bad, and that was a deal breaker for me, since I spend at least 3 hours a day in a car commuting.
Hope it works out for ya!
Bluetooth and wifi work perfect for me. The sound from my BT beats are great.

I just got my HOX+ over the weekend. The bluetooth quality seems ok, and the music/audio over BT sounds great (better with Beats on). The issue I have is it does not auto-reconnect with my BT speaker (Jabra Cruiser 2). I can't even manually reconnect it. I have to unpair it and go through the pairing process each time. Anybody else run into this issue as well? My Jabra reconnects every time with my GF's iPhone 4s. Not sure if this is a deal breaker for me as I only drive on the weekends, but still, it's quite annoying.

[Q] Anyone else here not able to like the One X+

I know the hardware should be capable, and I feel like I'd be happy with it if it didn't have **** drivers, but what can I do about that?
I had a Galaxy S3 on Sprint, replaced it with an LG Optimus G. Had to get off Sprint's network so grabbed a pair of these on AT&T. I wasn't interested in waiting on the One.
I bought it because I needed a phone and it felt good in my hand. I was never sure who's hands they designed the S3 for... but that's neither here nor there... I never imagined the fastest Tegra3 would be slow, or that the audio would be so horrible.
Do I just have bad phones? We have two phones, and the slowness is not limited to mine.
All audio (bluetooth or 3.5mm, streaming or local file, beats on or off) suffers from random cutting out and skips.
The stuttering transitions and the split second delay between pushing a button and something happening is mostly noticeable when done beside my S3 or Optimus G; otherwise it just feels generally slow.
I only get cutting out/skips with audio when i'm running slacker radio and the screen is active. If the screen is asleep, I have no sound quality issues with slacker. With regular MP3s, I have zero audio quality issues other than A2DP which is a simple bitpool setting that will get fixed by ROMs, but AUX connection sounds fantastic.
I don't see any of the slow or stuttering issues you are describing.
I'm gonna update to the latest stock image, and play with mp3 off flash. I've had issues with Spotify, Pandora, and subsonic. Come to think of it, I rarely listen with my screen off; I'm always at my desk at work and leave it on for the cover art and controls.
What ROM do you use?

I have used stock and elegancia. Both had the same music/sound issues. I think it is more of an app issue somehow.
I had the HOX before coming to the HOX+ i had some of these in playing music, but after a service it was fine. I think you have a bad phone. As far as the delay/stuttering it should be because of a rouge app which is slowing down the phone.

Bluetooth Quality Worse?

Hello,
Recently migrated from a DInc2 running Skyraider Zeus to the Dinc4, currently running the stock ROM.
Question: The Bluetooth audio quality in the DInc4 is considerably worse than its predecessor. While I can pair and use accessories without problem, the audio sounds muffled - regardless as to whether it's my earbud or the hands-free unit I have in the car.
Is this an issue with the current version of Android, the stock HTC ROM, or perhaps just my phone?
Comments welcome...
Thanks,
GG
I wouldnt really know about Bluetooth because I don't use it at all but this has a better connectivity with Bluetooth 4.0 but it could be just stock causing issues.

I use Bluetooth for both calls and music and have excellent quality in one of my vehicles. However, in my other car it does sound a bit muffled. I think this is due to my Bluetooth I have in the car not the phone itself.

I use bluetooth headphones on a daily basis and I haven't noticed any difference in audio quality between this phone and my other devices. Sometimes audio will cut out for a couple seconds on rainy days or when I walk too far away from my phone, but I haven't had any audio quality problems.
Hmmmm...interesting. Thanks all for the responses.
