[Q] Nexus 5 Bluetooth and wired headset problems

Hello,
Pardon if this has been answered already, I simply did not find my exact question answered.
I am using my unmodified Nexus 5 (not even rooted), with the latest KitKat (v.4.4.2 build KOT49H) with quite a few wired and wireless headsets and people always complain they cannot hear me. Eventually I got my hands on an old Samsung Galaxy S2 and tried my best bluetooth headset with it: Imagine my surprise, I could hear myself quite clearly even when I was talking really really softly, barely above a whisper. My headset is excellent. My phone is not.
My questions revolve around what to do about it.
Nothing in KitKat allows me to adjust the bluetooth microphone gain, nor does it let me use an equalizer on my microphone. I can adjust the volume of the headset, but this does not do anything to the microphone gain.
So...
Question 1: am I the only person with this problem?
Question 2: what do you people do about it?
Question 3: are there any mods / custom ROMs out there that attempt to fix this problem? Google does not appear to be interested in doing so.
Thanks in advance!

*bump*
Any ideas? I have tried re-pairing my bluetooth headset - no go. I have tried flashing custom ROMs and kernels - no go again. It seems to be a problem with the phone, but I have no idea how to fix it. And Google searches always return other people having this problem. Noone with solutions, though.
Using a wired headset results in even worse results, if that were at all possible.
Has anyone tried to replace the bluetooth stack or driver with something that works?
Thanks!

*bump*
Yesterday I spent quite a few hours tinkering with my phone. I tried every last radio out there for the Nexus 5 and none had any effect on bluetooth microphone levels. Then I tried a few AOSP ROMs: CM11 and Omni. They turned out to be so closely related I might as well have just tried one. None had any effect on bluetooth microphone. Heck if CM11 doesn't do it, there really are no alternatives out there! I tried the FauxAudio tweak, even paid $2 to Faux, which successfully managed to do nothing: app didn't was written badly. Finally, I tried a bunch of volume boost tweaks. That worked, actually. That is, it boosted the wrong volume. Finally, in a moment of true and utter desperation, I opened an ADB shell and edited that mixer file by hand. I then discovered that microphone gain on bluetooth is not controlled there.
I tried all my wired headsets again: Etymotic HF3's microphone produces such an atrocious sound, if I am to rely on it I need to seriously consider becoming a mime. Then there were my Bose QC15 headphones with a remote cable for Android by some off-brand company: that was terrible, the cable is useless. Heck, not even mime lessons can help me there.
Eventually I chanced upon an old microphone cable for my QC15 headphones. Just microphone, no remote. Surprisingly, this one is loud and clear! That after being anything but loud or clear on my old cell phone. Interesting. Unfortunately, it's been out of production for a few years. My working theory is that Bose realized putting a decent microphone on expensive headphones gives people real value, makes them spend money, and that way lies madness. We can't have that, can we. So when that cable starts cutting, so does my use of this cell phone.
I am screwed.
In any case, I will stop bumping my own thread, you guys obviously don't know a solution or there would have been a lively conversation right now. And I am pretty sure there is a moderator or two frowning right now, possibly getting ready to throw an encyclopedia at me. My only hope is that Google is going to do something about that pesky Broadcom driver that doesn't work sometime before the mass exodus to the iPhone. And before my precious microphone cable stops working, or I will be leading the way for that exodus. It's a phone, damnit, if it doesn't work like one it's no good.
Hmmm.... it should be possible to wire a good lavalier mike on a cell phone cable... maybe I can get an op-amp from an old tape recorder to get decent amplification... When attaching a 9V battery on my headphone cable begins to look appealing, we really have a problem.

Yes, if nobody reply you is because no one can help u.
But for what it's worth, i had an Xperia Play for 2 years. Using an Motorola Bluetooth Headset H350 while driving and a MW600 Sony Ericsson Stereo Bluetooth Headset, both never had a problem.
Now from 2013 Christmas both headsets with my new N5: still never a problem and not noticing any low volume or mic. Sorry

same issue

hi,
i am having the same issue with my Nexus 5 in combination with my Logitech H800 Wireless headset (people can`t hear me).
Anybody who did find a solution for this?
Thx

No solution. I tried everything, everything I could think of. I got FauxAudio to work eventually and that did nothing for Bluetooth performance (and it said it wouldn't, but I was desperate).
I returned a lot of high end bluetooth headsets over this issue. Eventually I came upon the Plantronics Voyager Legend. I would like to tell you this really expensive headset works fine, but no - microphone gain is still low, though this time around people can hear me okay. Not great, just okay. I am using that now. It's not perfect, it's far from perfect, but finally usable. Sort of. If I speak loudly.
For what it is worth, the ElementalX kernel improves Bluetooth stability on the N5 quite a bit. Microphone gain is still low, though. Another thing that sometimes helps a little is turning off the multimedia profile on the headset, though why THAT would make a difference is beyond me.
All we can do is wait, watch the Samsung Galaxy S5 get released and wonder if we should switch.

Somebody advised me to download the app "persist"
This is free from the playstore.
Can you try this and let me know this is working for you?

This app controls the bluetooth volume, not the bluetooth gain. The bluetooth volume was never a problem.

Ok,
i am having the problem with my Logitech H800 headset with the nexus 5.
So this is a android kitkiat 4.4 issue?
Or is this problem only on several Nexus 5-devices?

My guess is either the bluetooth baseband or the bluetooth kernel driver used in the N5 is flaky. This is why I think so:
Problem does not exist on my old Samsung Galaxy S2, including when it runs the same nightly of CM11, nor does it exist on my computer or my desk phone. All the headsets I've owned performed admirably there, so the headsets are not directly the cause. From what I've seen no ROM and no kernel out there seem to be making a difference as far as Bluetooth gain is concerned, the problem is persistently there and the same. Best I could tell it's just the N5 with a problem and it's just for the phone profile. I've tried the Bose headset (the worst performer headset with the N5 of the lot) on a colleague's N5 and his phone was just as bad with it as mine. I am not sure if it's a small batch of N5s having a problem, I don't own lots and lots of N5 phones to try on, but I doubt it: with anything digital things are usually all-or-nothing and the N5 has an off-the-shelf Bluetooth chip, which is not unique to the N5. My guess is it's the entire model, but having only tried on 2 N5 phones, this is no more than a guess.
From what I saw online, the entire Nexus line has poor Bluetooth performance, not just the 5, and Google changed the Bluetooth stack with KitKat besides possibly introducing more problems. If you have a non-Nexus phone, the manufacturer most certainly replaced the Bluetooth driver and radio with one of their own, so problem goes away, but the Nexus line does not enjoy such attention.
An interesting thing to try would be for someone to put the LG G2 Bluetooth driver on a N5 kernel and try it out. I don't have the time or the expertise to do that, but there are plenty of people who do. Assuming the G2 does not have problems with bluetooth gain, if the problem still persists it will tell us if it's the N5 baseband or hardware doing it, and noone can help us there if that's the case.

I have this problem too, using my Nexus5 with iphone headsets. Peoples told me in skype and hangouts, that they hear me bad...

That's a different problem. The wired headset problem is easily solvable with FauxAudio and a supported kernel.

This maybe realted to the changes Google made to the core Bluetooth stack as of Android 4.3+ I know they made adjustments for the BLE [low poer Bluetooth devices like pedometers and other senor type crap]. It is BEYOND me as to why Google keeps adding functionality ot the core Bluetooth stack when it is GLARINGLY OBVIOUS they have real problems with Bluetooth as a whole. WHY NOT fix the core issues so Bluetooth is much better at the basics before trying to add functionality or more complex?
I know they complained it would cost a bit for a different newer Bluetooth license but I mean in my personal experience with many different phones Bluetooth is SUPER flaky even at it's best in Android, and does not even work the same way across devices [I have used 3 different Jabra speakerphones on my bosses Galaxy 3 recently and they all worked to varying degrees even though they all use the same version of Bluetooth protocol], but my T989 [Galaxy 2 T-mobile], my parents G2s My bosses older Bionic, My fathers new Droid X, etc. all have random problems. You can usually find one device that works well with a certain phone/ROM, but that can change between ROM versions and devices so it is like you need to go and buy 1 of everything every time there is an update and go crazy finding the ONE that works [and as noted on page 1 with the gentleman using the same Platronics Voyager Platinum as I have it is a super expensive very nice device that worked BEAUTIFULLY in ICS, but now in 4.1 + you can not get more than 1 or 2 words across the mic unless you are YELLING at it like a crazy person on the SAME device].
So all that to say I think it is prolly related to changes Android made in 4.3+ flipped the Bluetooth operability on it's head.

Mic Volume OK with KitKat 4.4.4 and cheap "HB-800" headset
there've been no posts for a while so maybe the problem has gone away with the KitKat updates.
But anyway:-
I have a Nexus 5 and recently bought a cheap generic stereo earbud headset with mic from eBay .... $14.82 Ozzie including delivery to Western Australia.
I've actually asked the other party whether they can hear me (specifically "am I loud enough?") because I read this thread and have been assured that it's all good.
In fact it's a pity the sound quality at MY end isn't better, but that's probably the low quality ear buds rather than electronics / firmware reasons.
Of course, ymmv.
Here's the ebay item title in case anyone wants to look it up or I can pm the item number if it helps.
"Headphones Earphones with MIC 1st Stereo Bluetooth Hands-Free Wireless HV/HB-800"

No, the problem is still there. Reason there are no posts is that no one has a solution. Nothing has changed since March. I am somewhat controlling it with CM11 running on the ElementalX kernel. Without this kernel Bluetooth performance is unbearable. With it it is barely adequate.
It's funny that a cheap headset would work okay while multiple top-of-the-line everything-but-the-kitchen-sink models like the Plantronics Voyager Pro would still be having problems.
I was seriously considering getting the OnePlus One, the Nexus 6 and even the iPhone 6 hoping the issue would finally be fixed. It's ridiculous that a phone commonly accepted as the measuring stick of the Android world would be having problems with simple tasks like driving a bluetooth headset. *very disappointed*

Me too. Two days with my new N5 and when I use my Sony SBH20 people hear me bad... With my N4 no problem. Its annoying! Ive to speak with headset because Ive problems with my left arm and legs, I only have the right to hold the phone, I cant do anyhing more and when I walk I need that arm to hold my cane.
I dont see a real solution, I will have to return the N5

Bad sound quality through Bluetooth

I'm having bad sound quality when making call through Bluetooth in my car. It sounds like the audio is breaking up. Anybody else have this problem? My note 3 was working just fine through bluetooth

I also noticed the same thing yesterday driving home. I did not have this problem earlier in the week. I'm not sure what is going on. This along with a strange wifi problem has recently surfaced. If I leave my wifi range and then return, it does not want to reconnect. I have to toggle the airplane mode then wifi will reconnect. I am running stock 11s rooted with 2.7.1.0 TWRP, Xposed framework, Xpoxed GEL, Gravity Box, Tasker, Autovoice.

I am. I'm looking for suggestions for things to try and improve the stuttering/skipping/dropouts that I'm experiencing when using my OnePlus One in media playback mode through my Chevrolet MyLink car radio. I have some additional details to offer and things I have tried:
1) The playback application doesn't seem to make any difference, the problem is most pronounced (unlistenable) when playing back music files and is highly annoying when listening to speech (e.g. podcast) files. I suspect the difference is the music having a beat that gets interrupted while there are some normal pauses in speech so the stuttering blends in a bit more. In any event, it's not a problem with the playback application.
2) It seems unlikely to be a problem with the car radio (Chevrolet MyLink). Though I haven't done extensive testing I have done some using my old Motorola Atrix HD with a nightly CM11 on it from a few weeks back and that does not seem to have the issue, or at least it is not nearly as severe.
3) When I use a third party bluetooth audio receiver (some cheap no-name one from ebay) the quality seems to be fine but when I try to go directly to the car stereo I get tons of stuttering/skipping/drop outs.
A friend suggested that I try running an alternative kernel and see if that improves things. Any ideas on whether that may be the case or which one might be the best to try? Any other suggestions? It's quite annoying that I can't playback audio through the car radio...
Thanks!

Anyone have any ideas? I tried running the Franco kernel tonight and it seems to have the same issue. I did some logcat captures and I seem to be getting a lot of "W/bt-btif ( 2104): btif_media_aa_prep_2_send congestion buf count 24" messages when playing back audio through the car radio. See the attached full logcat captures with both the stock and Franco kernels and connected to both an alternative Bluetooth dongle and to the MyLink car radio.
Any suggestions?

After further testing I was able to determine this is an issue with the phone and not the car radio as I was able to find at least one other BT device which exhibits the same issue. I have created a ticket for this issue at: https://jira.cyanogenmod.org/browse/BACON-1005 if you are also experiencing this issue you are encouraged to go and vote for the ticket.

One question though. Do you have WiFi on when traveling in your car? Try turning it off and see if you still get skipping.

I do in fact have WiFi on at all times. I tried turning it off for the day today while doing some driving and it appeared to clear up the problem. I would think it's still a bug because having WiFi on should not prevent BT audio from working correctly but it at least gives someone a direction to investigate.

So I've done some slightly longer term testing and what I can say is the problem is not totally cleared up when WiFi is off but it is much, much better (definitely listenable). I will still get a couple dropouts when first starting a stream (sometimes, not always) but after 30 seconds to a minute it seems to settle down and be fine as long as I keep the WiFi off.

Just to clarify the situation..
My Xperia Z2 have the same issues.. It is not your phone but the Bluetooth stack in android that pretty much sucks the problems you are dicribing has been there since android 4.2 on a lot of devices.
I have just changed my Lumia 1020 out with this Z2 and call me disappointed in music quality! On the Lumia you would have trouble hearing a difference between jack/auxiliary and Bluetooth..

And today I did notice some dropouts even with WiFi off well into my drive but it was just a few packets I would guess more of an annoyance than a serious problem. I've heard about issues in the Android BT stack but the confusing part of that is why certain devices (such as my Atrix HD) don't seem to experience the problem.

I have a bluetooth stereo I use every morning in my home and a bluetooth stereo in my car. I almost exclusively use pandora, but I have also used power amp on longer trips. I have never experience this issue with my opo. I have ran 25-33 all rooted with no problems and am currently using CM11 nightlies. I also am not having any wifi issues.
Sorry it's not very helpful, but it doesn't sound like a widespread issue at least.

It certainly has something to do with the particular bluetooth implementation used by the receiver interacting with the OPO. As I indicated I have three different BT receivers I can test with and the problem affects two of them but not the other.

Poor Bluetooth audio quality

I just got the tmobile variant s6 and immediately went to test the Bluetooth audio stream on my 2015 gs350. I noticed a crackle in the audio. It is minimal but quite noticeable at high volume. This is disappointing as my Sony Z3 had excellent BT audio quality on my gs. Anyone else notice this?

I do not seem to have that issue over my car's bluetooth. T-mobile also.

I'm getting good audio quality via my Sony SBH80 aptx BT headset. Perhaps you can play on the Sound Alive equalizer.

Just wanted to let you know that I am having this same problem. When streaming music in high quality from Google Play, the treble is all crackly and distorted. It's really disappointing. I'm going to do some testing today against my old m8 and using non-streaming music. But never had this issue before.

It's probably the fact you are streaming audio. Try some high quality downloaded music, like from Spotify. I've no issues at all.

I am also having the same issue with the Verizon version of the S6. It sounds terrible over my car Bluetooth when streaming but sounds good through my bluetooth Bose headphones. I didn't have any trouble with my car Bluetooth with my iPhone 6. I really hope Samsung gets this sorted out with a software update.

I too am having issues with streaming bluetooth. I think that my issue with it is amplified, because I normally listen to music only on my Magnavox Turntable, and the sound from that console is unbeatable by any electronic streaming or mini-speaker. My son bought me a bluetooth speaker for my birthday last year, which was very nice of him, but the sound just does not compare to the 1970's technology.
Maybe I'm just old.

Do you happen to have any bluetooth le devices, like a fitbit, attached at the same time? I tried disconnecting my garmin vivosmart and there's a dramatic improvement.

Same here. Lowering the treble help a tiny bit but what's music without treble . I've tried disconnecting my pebble watch but no dice. I really don't want to go back to aux.

In my car, before I disconnected the Garmin, I found that adjusting the toggles in Play Music - edging the first dial two toward Treble and the other dial three toward Instrument helped a bit.

I noticed the crackling on treble as well. As evanl81 suggested, I disconnected my Moto 360 (switched it to airplane mode), toggled the phone's bluetooth to have a fresh connection to the car, and the crackling is gone by at least 90%!
Very disappointing. Didn't have this problem with my Nexus 5. I'd very much prefer to not have to disconnect my watch every time I get in the car

That would be a problem. I'm starting to think that we are wirelessly connected to too many things!!

So it looks like my pebble watch was the problem. Seems i can't have other BT devices connected while connected to my car. Once I put my pebble in airplane mode, then off/on the BT radio and all is good! Sucks but at least it's a workaround.

I'm trying to use AutoInput and Tasker to automate the disconnection and reconnection of my watch when connected to the car bluetooth right now, still working out the kinks though. :\ Endless little things and inconsistent behavior.
It would be fantastic if this gets fixed by Samsung at some point!

No, I have a Nexus 4 with 5.0 and now with 5.1 and its connect to LG g watch, a parrot ck3100 and auki bluetooth reciber and the quality is perfect. With S6 I only connected to my LG g watch and auki and the audio quiality is a ****.

i don't know about bad audio quality for bt but i get audio cut outs and choppiness when using my jaybird bluebuds. it gets really annoying. i noticed it happens in wide open spaces too like when i'm outside but not near any walls or enclosed areas. if i'm indoors, it works perfectly fine. i remember reading about the way bt works and the signal needs to bounce off other surfaces or something like that in order to work properly. i had this same issue way back in my OG Droid days and there was a build.prop edit to boost the signal by giving bt higher priority.
anyone else have this problem? i'm on VZW variant btw.
other than this issue, bt audio sounds perfect. i also use Viper to give the audio volume a major boost.

I'm having the same issue on my car audio.
It was perfect with the Nexus 5, very disappointed to have this with the S6.

I just got my sg6 have a samsung gear live and bluebuds x I get crackling sounding high end, very annoying, coming from an HTC one m7 with the same setup and had zero problems, really hope they are able to fix this!
OK so I enabled the tube amp setting and nothing else, it seems to have made a huge difference. I can now listen to music without cringing. Hope this helps.

Ok, I made a few findings about the issue. I also have a moto 360 connected to the S6 and the crackling is so high that is imposible to hear music with a minimum of quality.So i tried with the watch off or in airplane mode and the crackling is still there but sometimes it dissapears after connect and disconnect the bt devices but not always. Now, the elephant in the room:
I have a Samsung Hs3000 bt stereo headset and the music quality is superb even with te moto 360 connected. The magic is that this particular device has aptx codec included. So if you have an aptx bt device the quality its going to be there. For no aptx devices i'm trying an experiment: i remember from the nexus 7 2013 and other android phones that bluetooth audio quality was bad since kitkat and the problem was bluetooth compression was too high. There are two files that control this behaviour: audio.a2dp.default.so and bluetooth.default.so. If we could edit this two files maybe we could fix this. If someone can help me and tell me what program can i use to edit this files on my computer i'll try to fix it myself.

Just wanted to follow up on this thread - I recently switched to the Note 5 (which I love) and also got a Huawei Watch. When the watch is connected to the phone and the phone is connected to bluetooth, the sound quality is really horrendous. So I'm guessing it's something with the BT smart implementation in Samsung phones or something? It's really annoying. I too tried to work out some stuff with AutoInput, but it's a huge pain. The only real workarounds are to put the watch in Airplane Mode or just disconnect through the Android Wear app. And unfortunately there are no shortcuts through AutoWear. Oh well.

Solve a bluetooth mystery. Audio stutters up close but is fine from afar

Since android 7.1 I can't use my bluetooth earphones with my Nexus 5X. I'm this close to selling up for a different phone.
I can pair my Nexus 5X to my Anker earbuds, but the sound drops out so much it's unusable, stuttering several times a second.
The weirdest thing though; the problem is worse when my phone is near my earphones, like when I hold my phone up to see the screen. When the phone in my pocket or across the room, it works OK.
The problem is also worse when the screen is on than when it's switched off.
Can anyone help solve this? The fact that distance helps makes me think it's maybe a weird bug related how 7.1 manages bluetooth power and interference? A Bluetooth LE thing?
For reference;
It's a Nexus 5X, currently running stock 7.1.2 beta.This problem began exactly after the 7.1 update.
I'm using Anker Soundbuds Sport earphones. It's not the earphones, I've tried another identical pair. They also work fine with other phones.
Bluetooth works fine with other devices; my soundbar, bluetooth speaker.
I've tried rebooting, full factory image flash, every wipe possible.
I've tried Lineage OS, including flashing that aptX mod.
Let me know if you want any more info.

Bluetooth Audio issues

Ladies and Gentlemen,
I am having the oddest issue with my phone. The u11 is 99% amazing, to me. I really like everything about it......
-except-
When paired to my 2013 Dodge Dart (don't ask. big mistake) the music audio plays slow. I don't mean the speed of reaction as far as switching tracks or how long it takes to play the next song... I mean it sounds like the audio is pitched down by about 20%.
Things I know/Have Tried from a troubleshooting perspective..
The phone bluetooth audio works fine.
The audio, when connected to the aux jack, works fine.
The audio, when connected to OTHER bluetooth devices such as my HK Aura plays fine.
My phone and car are updated to the latest firmware.
I realize that the conclusion is going to be "it's your car dude".... but since it's not so easy to get rid of the car... and I don't really want to swap this phone out for a Galaxy......
Is anyone else experiencing this? Has anyone had this and sourced a solution?
Thanks.

I've used my U11 in my 2013 Dodge Grand Caravan (don't ask. big family) and it performed flawlessly.
I imagine they are on similar systems, mine is just the standard UConnect head unit. This happens will all media streaming?

Yes standard head unit. strictly an LED display with knobs.
Yes. It's across the board.
Google Play
Pandora
Tidal
Netflix (it's trippy to watch the video move at regular speed while the vocals are not only behind, but pitched down!)
I've also tried varying bit rates on my personal MP3s.
I have a hunch that this has to do with the audio in the phone being 24bit and the radio converting to 16 bit, but I have nothing to base that on...

Basic suggestion - unpair and re-pair to see if that resets something.

I've connected my u11 to two different cars so far (an Infiniti and a Land Rover), and haven't had that issue.
I've also connected to a plethora of BT speakers, with no issue....

It is probably your car. To be honest, I think it's a UConnect issue that doesn't play nice with HTC phones. My HTC 10 had basically same issue I'm having now where music sounds like garbage, distorted. The U11 is even worse! I believe my head unit is the RHB model in a 2011 Ram. But 2 phones now with same issues, can't be coincidence.

The classic, of course.
I did pair and unpair a few times even going so far as to to completely reset the car radio from any pairings.
no luck, but thank you for the suggestion.

My HTC 10 had basically same issue I'm having now where music sounds like garbage, distorted. The U11 is even worse! I believe my head unit is the RHB model in a 2011 Ram. But 2 phones now with same issues, can't be coincidence.

yeah, based on everything else I've done. It is most likely the car. Unfortunately I use that feature way too much to over look it...
Thanks for the input.

I have yet to test my wife's Samsung s8 to see if the issue carries. Not a good test though since the s8 has Bluetooth 5.0 but it's all I've got ha!

I have a similar issue, my U11 stutters and warbles and is generally unlistenable when using my tunelink (for android). However, when playing music through my Bluetooth headphones it plays perfectly, when playing through my Bluetooth speaker it plays perfectly and finally when playing through my Bluetooth headset it plays perfectly. Tried on my sisters car stereo and it plays perfectly. Its just the tunelink that has a problem. Tried a S8 and it plays perfectly through the tunelink, as does my 10 and my M8.
Edit:
Have bought another adapter to test and this also connects and plays perfectly with my U11. I guess it's just a compatibility thing with the tunelink.

Hey I have the same problem in my U11 and 2012 Dodge Challenger (ask, I love this Car!!)
The only solution I have found is if a restart the app on the phone then the playback is good. but I do wish i could just connect it and it would the playback would run fine like my old HTC M9.

Just to add to the thread. My u11 is slow to connect to my 2014 pilot and 2012 infiniti. Why it does connect it always disconnects. I'm on us unlocked 1.16 firmware.
I've read there is issues with Android 7.1.1 and 7.1.2 is better but searching the internet it does not seem the issue is too wide spread.
Edit. Testing with Wi-Fi on, not connected. So far so good

I have similar issues. I have a Subaru Outback (2015) and while my previous phone (Nexus 5) and my kids' iPhones all sound fine, the U11 sounds terrible when connected via BT. It is very grainy, like a sample rate mismatch. Same result in all audio apps. The U11 sounds find when connected to my Bose BT headphones. It's just some weird incompatibility with the car. Extremely frustrating. Its 2017 people!!
