Buzzing/Humming Sound

Hey All -
I ran a quick search and didn't find this problem. I wanted to document it for posterity.
My phone makes a buzzing sound. I've seen it in every ROM I've tried so far (seems to be a hardware problem).
The sound is faint, is unaffected by media volume, and goes away when wifi is turned off. The phone appears to shut off the sound hardware when sound hasn't been played for a while in order to save battery. This makes the buzzing stop. But if a notification comes in, or there is a quiet part of a song, you can totally hear it.
It exists regardless of the ROM I have installed.
The sound is like what you'd hear in an older computer with something called crosstalk. Back in the day, (and to an extent still), various components in the hardware would generate EMI and would affect the sound quality in sound cards. For example, I had an Adlib card that would buzz a little every time the hard drive would read/write to disk.
This sounds just like that.
Anyway... just vote in the poll/comment if you're having this problem. Please post to the thread if you have a solution. I'm not expecting much though. I'm pretty sure I'd basically need a new phone for this to go away.

I get a very slight buzzing in my phones, completely unaffected by wifi. Only happens with my CX300 in-ears, any open earphones i havn't heard any noticable buzzing (though have no tried any type of headphones yet). Using Voodoo sound, lowering the amplifier dB gain and putting the media volume up reduces it a touch.
I grabbed a pair of iphone earphones and the nexus s earphones to test it with some more types, no noticeable buzzing. Also, both their sound quality is appalling in comparison to cheap sennheisers.

Yeah, that's different than me. It sounds like your CX300s might be dying.
I've got some Klipsch S4i ear buds and Bose QC3s that both have the same problem. Its loud and clear enough though that I'm sure I could hear it with cheaper headphones.
I can turn the volume all the way to zero and still hear it. When I turn it up, it doesn't make it louder though, which is "nice".
I've been all over the voodoo sound settings and nothing helps.

That's a shame, your phone probably suffers a noticeable case of leakage between the components. Could this possibly be classified as a defect and be fixed/replaced under warranty?
Also, my CX300s have no hiss on a higher quality dac and it was noticeably louder on my old nokia. I guess they're just more sensitive, they are only 16 ohm after all. No drama for me

It might qualify as a defect. I'd have to bug Samsung I guess. I could see Samsung just telling me to deal with it. It doesn't make a lot of business sense to replace a $500 phone because the headphones hiss when wifi is enabled.
It would sure make me a lot happier about buying Samsung stuff in the future though.
That's really weird about your headphones. Unless the audio quality on the CX300s is far superior over the iphone/nexus s ones, I would expect them all to behave the same way. Even then, it would be very subtle. Maybe the Nexus S doesn't ground the headphone jack very well for your headphones?

You could give them a call/email and see how it works out, but you'll probably be left without a phone for a few weeks if you send it so probably not worth it for you either.
Definitely far superior in comparison, but not nearly superior earphones Possibly a grounding issue, could even be just an unlucky set of Sennheisers that i got and have always been like this. They are out and about anyway, take a good beating and have been rock solid. Hopefully soon i'll be getting a decent pair of headphones for home use, funds allowing.

My laptop does the same thing, I'm thinking it is just interference with the headphones and your phone. might also be a lose wire or something in the phone or headphones :/

I know that this is old tread, but I had the same problem and solution might help someone.
In my case, the source of the buzz was charger (poor power supply filtering in cheap switching sources). I bought some cheap car charger/dock, and whenever I plugged my phone into it I would get lots of buzzing noise. Of course, I used it every time when in car, so I did not notice correlation for a while.
Using better charger solved my problem.
If by any chance you are charging your phone while you listening to music and getting lots of buzz, try disconnecting power cable to phone and see if there is noticeable difference. If there is, you found your problem.

Thanks for letting us know grejigl. Although not the source of my particular (non) issue, i can see it helping out someone else down the road.

I'm running on battery power when it happens to me. I'm pretty sure its caused by something related to WiFi because as soon as I shut WiFi off, the buzzing is gone.

Is it safe to...

I was wondering if anyone charges or tethers their phone by the USB port on the dock. And if u have any issues doing so. I tried and I can hear an odd whiny buzz sound from the connection. It would be nice to do as long as I am not going to fry it. So if you have been doing this without problems for awhile plz drop a line about ur experience.

I am tethering my EVO 4G to charge the battery. Haven't noticed any buzzing. Using WiFi Tether for the Internet.

The sound is extremely quiet. I have to put my ear close to hear it clearly.

If that's the case I wouldn't worry too much. If it was loud enough to be heard from a distance, or over ambient noise then I would take a closer look at it. Electronics does make all sorts of noises (think of the old flyback transformers in televisions before they became all solid-state), especially if considerable current is going through it. Also flyback transformers are still used but on a smaller scale in switching power supplies. They generally operate in the 15-22kHz range. I bet you're a very young person since most people by time they hit their mid-20's lose the high-end of their hearing due to normal aging (faster if they listen to loud music/attend concerts like I did).

Review: LG HBS 730 bluetooth headset

This is my review of the LG HBS 730 headset with the Nexus 4 Android 4.2.2
Overall, I would rate this device a 9/10 and suggest anyone with a Nexus 4 or Nexus 7 buy it if they're looking for a stereo headset.
My previous headset: Motorokr S9HD
Great headset, loved it, and sturdy. One problem... If you run long distances (and sweat a lot) it dies on you. When i run, I run anywhere between 5km to 13km, and the sweating from the 13km runs pretty much kill the S9 within 2 months. I know, I had it replaced 3 times
Pros:
- Good distance with Nexus 4. There have been times that I walk 10 feet away from my phone without a single issue with audio quality
- Very good battery life. Charges very quickly and takes a while to run out. I've used it for 8hrs and the device still only reports "medium"
- Buttons: All work as expected. I can raise and lower the volume, skip tracks, etc. without a problem. I've tried it on the default music app for the Nexus 4, doubletwist, and pandora. They all work perfectly
- Connection: Always connects. I simply turn on my N4 and my HBS730 and 10/10 it always connects
- Multitasking: While using the device, I also using various apps, like JeFit, GMAIL. whatsapp, etc. and it doesn't stutter.
Cons:
-When running fast, 12km/hr, the device bounces and I question if it'll come off. It hasn't, but I do question it.
- Magnets, they're weak. The ear pieces constantly come off. If you lay them down, they'll stay on, but put them in a backpack and they ear pieces will come off the magnets. Not a big deal.
Apt-X, I can confirm that the Nexus 4 does NOT include Apt-X.
Overall, if you're into cardio excersices or exercise long distances, you'll really appreciate this headset. I've also used this devices with my Nexus 7. I use it mostly for reading and listening to music. The nexus is never more than 3 feet away from the device. It always works perfectly.

I've had this headset for a month now. I'm coming from the LG HBS-700. I've noticed that the audio doesn't sound too good if the volume is all the way up on the Nexus 4. It sounds much better if you control the volume from the headset. I never had this issue with the 700's. I think it's due to the lack of apt-X.

How was HBS-700 on Nexus 4 for you? I'm planning to purchase, but the reviews on HBS-730 aren't as positive as for HBS-700.

i am also planning to take bluetooth headset and
confused between hbs 700 and hbs 730
can u guys advice me which one should i purchase
i wont b using it for running or during excercise, just for listning music while going to office and home

I had the HBS-700 for about a year, loved it, used it almost every day at work, anywhere from 1-6 hours per day. Used it for working out. I didn't baby it one bit, and it was still going strong when I lost it. This was when I had a Galaxy Nexus.
I suffered for about a month before I finally broke down and replaced with the HBS-730 in early January. I can report that I don't have many connectivity issues as reported on the Amazon reviews, so perhaps the Nexus 4 just works better than some phones. I can still get nearly 30 feet away before it starts to break up... usually. The odd thing is that the sound will occasionally break up while I'm out for a run or other times when the phone is less than a body length away. This did happen on occassion with the HBS-700 and Galaxy Nexus, but seems to be slightly more with the 730. Not apples to apples, but I can say that it isn't enough to bother me, and the distortion only lasts a second or so before going back to normal. I think iPhones have some serious issues with this set but so far my Nexus 4 is all good.
Last week, my boss found my old HBS-700 behind a filing cabinet. How it got there I have no idea. I tested it for a night before selling it to another coworker, and did find that the 730 has better sound quality (or I should say, a sound quality that I prefer). As someone else mentioned, the bass will sometimes distort at high volumes, but you can turn off the bass boost which is on by default. There are three EQ settings (Bass boost/ Normal/ Treble Boost). Default is Bass boost. To change, press both + and - volume buttons and you'll hear a beep to confirm (first beep = Normal, 2nd = Treble, 3rd brings you back to Bass Boost...) You have to do this each time you turn on the headset, but I find the default bass boost is fine for most songs and will only change the EQ if I am getting distortion. (edit: to clarify, only the 730 has the EQ feature, the 700 only has one setting but I did not have any bass distortion issues)
I've had both models yanked off my neck by just the thin earbud cord several times, hard enough to the point I was sure something would break. I've sweated all over them. I've taken them to the beach. The only issue I have ever had was losing one of the small plastic clips that let you adjust the amount of cord between the set and the earbud on my set of 700's, and those aren't really even needed. Oh yeah, and even after a year of good use, I don't think I ever managed to use a fully charged battery in a single day with my 700's. Like the OP said, the battery on these things is great.
I purchased the 700's for my sister and for her boyfriend last year for Christmas. They are converts now as well.
So yeah, I love both models, recommend them both, but after listening to both side by side, I would have to recommend the 730 for the higher sound quality. Buy from Amazon so you can return if you have issues with the connection, but I think you will likely be pleased either way.
OH YEAH!! HOW DID YOU FORGET TO MENTION THE VIBRATION?! The neckpiece vibrates on incoming calls, so even if you have the earbuds stored in the headset and phone on silent you get your notifications. So simple, but so useful.

Worked great until it broke! Lasted me a little over a year, but I really abused it! Went on many, many sweaty runs with it, and wore it to the gym 4-5 times a week. I also wore it to school everyday. Money well spent.

Woah! Thank you so much! I did not know that! I was wondering why bass would sound distorted sometimes. You just saved me from having to return my 730's!
It would be awesome though if you didn't need to set it again whenever you turn the headset on, but it's whatever I guess.

I have experienced the too high of a bass issue too. I also wonder if my audio files are also the culprit, meaning the quality should be better.... Who knows.

Thanks to all of the positive reviews in this thread, I finally purchased the HBS 730 model from Amazon (the white version), and I love everything about. It works flowlessly with Nexus 4, though I still haven't been able to connect it to my Windows 8 laptop, but that's a Dell/Windows driver issue.
And I was impressed that most notifications actually come as a voice through the headphones, not as LED lights or something like that. E.g. when you turn on the headphone, a pleasant lady voice will say the battery volume and whether it's connected or waiting to be paired.
The voice during phone calls is clear for both sides (at least haven't had any complaints expresses) and the overall experience is much better than with my wired headphones that came with Nexus S.
The range is working much better for me - I was concerned about various issues expressed on Amazon about connection getting lost when turning the head or moving 4 feet away. For me, I can walk away to around 15-20 feet with 2 walls in between and the connection is still on.
Works great in the gym where you don't have to fiddle with wires. I still take it off sometimes when I do bench presses, so the headset doesn't fall off or when doing something like shoulder presses where the bar may touch the headset.
BTW, there's an app on the Play Store which reads out the text messages and the sender's name through the headphones - kind of cool if you mainly receive texts in English (though some other languages are supported too). It's called BT Reader.
I didn't have much bass-distortion issue, but that's because I don't listen on the max volume (headsets have separate volume control than the phone). Sometimes when I accidentally turn on to the max there is distortion, but I don't actually listen that loud. And the DSP Manager which comes with Cyanogenmod is quite helpful as it has separate settings for Bluetooth.
My only pet-peeves is the pulsating light around the call button - I don't know why it pulsates and don't know how to turn that off. I don't see the light anyway when the headphones are in use, but I'm pretty sure other people notice and fix their eyes on headphones/me for a while
All in all, it's an awesome, well designed, well thought-through headphones.

I like it a lot, just want to know if I can disable the play button on the headset. I rarely use my phone for music, and I often hit the button that starts my music. would love to be able to turn that feature off.

Got mine stolen 2 weeks ago -_-

I've had the HBS-700 for 1-1/2 years and used it at the gym and for running. One of the best headsets I've ever owned let alone seen out there. I'm going to keep mine until it breaks but I'll tell you that I will always go for this type of headset in the future. I hardly use the bass boost (like someone said hold down vol+&- at the same time to turn on).
I've never had problems accidentally hitting the play music button but I'm pretty sure you cannot disable it, at least on mine. The one thing I wish I could disable is the light that blinks constantly. Not sure if you can on the 730. If I need to check battery status, I simply hold down the vol down button for a couple seconds and you get a steady light: blue for full battery, purple for medium, and red for low. Just read the online manual or the one that came with your headset to find all the tips and features.

Got mine today, and modded it slightly to get better sound and noise isolation.
Using my old E4C, fitted it with a socket (like those being used by the current Shure SE series). The original earbuds have been cut off, replaced by a Shure plug. I also tried fitting my SE535 on it, which is a bit of an overkill, but it works nonetheless.
The stock cable/wire from the HBS-730 is a bit on the flimsy side, but does the job for the time being. Will probably give it a more durable cable at a later date.

Woah, this is awesome.

Anyone have Bluetooth distortion issues??

Hey everyone,
Found out my company is ditching Sprint for Verizon which means I have to part with my beloved Nexus 5.
Anyway, from what I've been reading on here it seems like the M8 is really the only Verizon phone that can be rooted. I've had a few HTC phones over the years, including the M7, but they never seem to get along with my car's stereo. The phone part works fine but when I stream music via Bluetooth there is always a great deal of distortion in the high end. Especially on cymbal crashes. This makes it pretty much unlistenable. I'm curious if anyone has experienced anything like with with the M8? I've Googled it a few times and found threads about the One X and One M7 having this problem but have yet to see anything about the M8.

I don't stream to my car often, but on the handful of times I have, I didn't notice any sound issues. This was using Pandora and Google Music, on a Ford (2008 model).

Just got my jaybird x's today and guess what. Filled with static. I could not be more annoyed with this particular phone right now. Three defects in one model I mean come on. Speaker crackle. Screen is creased and looks like you're pressing down on a TV and now Bluetooth has static

I can't say for certain, but I imagine bluetooth audio issues would most likely be due to whatever is actually playing the music, not the phone. Bluetooth audio, in general, is terrible - unless you're using something like the HTC Stereoclip which does not use that same audio codec that just about everything else does. You could have lossless flac files on your phone, and 9/10 times it's gonna sound like crap over bluetooth, no matter what the music is being sent from.

I stream daily over Bluetooth and it sounds amazing. Vzw.

Just plugged mine into my aftermarket JVC GPS stereo on a my truck which gets only occasional use these days. Have to say I was somewhat blown away when I pushed some Comfortably Numb into the 5 speakers (Inc sub) and cranked up the volume. Most impressive...
The wife gets terrific sound from her N7 to some small bluetooth speakers we got last year and has no issues unless she's using TuneIn at which point it goes from OK to awful.
I say this to simply point out that the invariable rule of YMMV seems to hold sway here but I don't think the M8 has any generic systematic failure with bluetooth audio.

This is true. But I'm talking hiss/distortion like a speaker is blown. I'm just streaming Spotify to my cars stereo and not expecting flawless audio but the issues I have with the M7 were unlistenable.

From what I understand, it has something to do with HTC setting the bitpool value too low. Which, in itself, might not be a big deal but it might just be a issue with that value combined with my car's stereo. I just don't want to lose root when I move to Verizon.

You could have lossless flac files on your phone, and 9/10 times it's gonna sound like crap over bluetooth, no matter what the music is being sent from.

Maybe the stereo in your car just sucks? Streaming Pandora over BT in my car usually sounds great. I mean granted it's not as good as using headphones, but it sounds pretty damn good.
Also, I streamed some more over this last weekend, and while the quality was still good, it did disconnect once for no apparent reason. And once it happened, I remembered that it happened a few weeks ago as well. Same thing, I was just driving along both times, and my BT just seemed to shut off. I turned BT back on, reconnected Sync (it's damned annoying how Sync never automatically reconnects), and it worked again for the rest of the weekend.

Thanks for the info.
I saw that an OTA for the M8 pushed out today (I think) that was supposed to fix some Bluetooth issues. I won't if the disconnects were addressed.
I'm M8 should be here on Monday. I really hope it works out OK. I don't want to send it back for an iPhone. :crying:

Another OTA? Has anyone else heard this? I am having a really rough time with bluetooth headset outgoing voice quality so some sort of fix would be awesome.

If the phone volume is at max it will distort. When I turn the volume to max while streaming Bluetooth to my car stereo it sounds crackling and distorted. Turning volume down 2 clicks to about 85% on the phone fixes it

It's not a volume thing. I've tried turning it down when I had the M7 and it sounded the same.

Again, sorry, but it may just be your stereo. When Bluetooth streaming to my car I always have my phones media volume maxed and I control the listening volume via the car volume, and it sounds fine.

Do you have an aftermarket stereo? I've had 4 different head units on my car, all high end Sony and clarion and all had same thing with max volume all my previous 3 phones ( rezound, s4, and m8). Just curious if it's just aftermarket decks that have this issue which I really don't consider an issue. I prefer to have the volume lower on the source and let my deck and equalizer provide the output anyway.

No, it's a factory Ford stereo. If you know someone with a factory BT compatible stereo, maybe try pairing your phone to their car and see if streams with or without distortion?
I mean, it's possible your particular phone itself could be bad. I just don't think it's all M8's since I don't have a problem, and because I imagine we would have seen a lot more complaints.

For six months I have been playing music in my car with a one (M7) via Bluetooth, with very annoying vibrations that eventually damaged my car stereo. I just found out that if I launch the media app via the "HTC car" app, the volume is much louder and I don't have those vibrations anymore. By default the HTC car app in the M7 only includes the default "Music" app, but other media apps may be added.
Hope this may help for the M8 too.
By these vibrations detroyed my car stereo, and I had to change it. I am pretty annoyed that HTC doesn't mention this anywhere, and leaves it to the user to find out.

Audio Problems Through Headphone Jack

I plugged in my headphones to the phone and heard horrible static/hissing in the background, particularly when the volume is over halfway. I've tried 4 different connections (to my car stereo, to my headphones, to an external speaker, etc) and they all sound equally awful. I really hope I don't have a defective unit... This isn't normal though, right? Anything I can try to do to avoid an RMA? I'm rooted, bootloader unlocked, on PureNexus with EX kernel. No audio mods.

Also, just two notes:
1) I am 100% sure the cable is plugged in all the way.
2) I have no issues with the speaker (which tends to be what people have issues with on this phone, ironically). Audio had no distortion through speaker, but through the headphone jack its horrendous. I can't even listen to it it's so bad.

Unfortunately (fortunately?) that's not my issue. I can hear music, it's just terrible sounding due to the hissing I'm the background. It's as if the cable is only half plugged in (but it's not). Thank you for searching though!

Google has admitted the audio distortion issue being reported in its Pixel smartphones is an hardware problem, and it looks like the company is issuing replacements for customers. The audio distortion issue was first reported in December when a user named Mark Buckman had posted about the same.

Wasn't Mark having issues with his internal speaker when headphones were NOT plugged in though? I think those are different issues. My audio is fine at full blast, as far as I can tell, with no headphones plugged in. It's just when I plug something into the headphone jack that I hear the problem. I'll try his piano and see if I can reproduce his issue though. Maybe I just haven't tested the internal speaker hard enough.
EDIT: Grr... I do have the other problem too! Shown clearly by the Perfect Piano app... Well thank you for leading me to finding that out!

Lots of people have a problem with the speaker. I've had 3 replacements with various faults and all have had the speaker issue. It's been reported that its a software issue, and will be resolved in an update..... Hopefully.

Weird. I spoke to Google today and 5 minutes after describing the problem, they told me to get a replacement through Verizon (that'll be fun).

Google can do the replacement too. I opted for that route because I'm hopefully more likely to receive one that I can unlock the bootloader on.

They will, but it will leave me without a phone for 2 weeks. They won't ship until they receive mine since it's through Verizon.

They quoted me 7-10 days max. I still had my old HTC 10 so wasn't really am issue

Did you try cleaning out the headphone jack with an electronic cleaner/compressed air? Dust could be a factor.
(Please correct me if these aren't the ways to clean a headphone jack)

It's not only the headphones jack I found out though. It's also the speaker when the headphones aren't plugged in. So apparently I have a jacked up phone, sadly. I may try the compressed air for fun though.
