Bluetooth stereo quality - iPAQ rw6828, XDA Atom General

I was playing with my friends Atom the other night (and I have one on order myself) and I wanted to see how the bluetooth worked. So, I used a bluetooth adapter on a computer to become a stereo receiver for the Atom. While I had no problems getting the device working, the quality seemed outragiously bad. I was playing an MP3 in Windows Media Player, and the sound played over bluetooth sounded as if it had a high pitched squeel over it the whole time. With this kind of quality, I question being able to use a set of bluetooth headphones with the Atom. The quality was not a problem in the MP3, and it sounded find out of the Atoms speakers. Was I having some other problem, or is bluetooth stereo sound just this bad?

On mine it sounds better on BT stereo than thru' speakers :lol: Maybe your pc corrupted the soundz

Well, I suppose "better" could be rather subjective. But when using the PC as a stereo speaker it sounded bad. I imagine with that kind of sound on headphones, my head would explode out of sheer pain. I'm certainly willing to accept that my PC bluetooth software could be causing problems, but I'd like to hear what others think before purchasing a set of bluetooth headphones. I would be describe what I heard as if it had been overcompressed sound with horrible high pitched artifacts. Would you say that the actual sound being sent to your headphones was phonically the same, ignoring the quality of speaker vs headphones?

Remember "Garbage in Garbage out" :twisted:

The same MP3 played on the computer it's being transfered to via bluetooth (and therefore the same speakers) sounds perfect. What I'm wondering is if bluetooth stereo quality is as bad as I've just experianced, or if it was something outside the normal "headphone" system that was causing this (such as poor receiving software).

Fortunately tonight while browsing the forums I came across the following,
http://forum.xda-developers.com/viewtopic.php?t=54621
This completely cleared up my sound quality issues. Sounds like what I'd expect now. Hope this helps someone else.

Tell me. Which settings did you apply? All or some of them. There are so many inputs you cannot even know ehich is which :roll:
I changed only Bitrate:
Bitrate 53 increased the frequency of breaks to almost one every 5 seconds. My original was the default 30 which was just fine at less than once every 2-3 minutes.
Am currently testing 35. Hissing is gone, but the ocassional cut is still there @ once every 2 minutes.

HT820 Problems

I just got my HT820 tonight and I am experiencing some sound problems.
The bass sounds fine. However, high pitched sounds is terrible. It is distorted and awful.
There is this ringing sound whenever there is a high pitch sound.
Anyway to fix this?
I saw a posting about some RegEditing but I can't figure it out because the last two registry entries don't show up on my Wizard.
Try a program with an equalizer so u can lower the treble like gs player
Well, that is a good temp fix, but it is painful to listen to people on the phone using the headphones and it would be great to actually hear sounds other than bass.
Any other solutions?
I have moto HT820, the only thing I don't like is mid, it sounds like putting a cup on the ear (hollow sound)
if not, I like this headphones well
now I have plantronics 590a, the sound had been distorted first, but it's gone after couple of weeks of listening, it appears the headphones needs to be "cooked", with Koss KTX6 earpads, the sound is pretty good, esp on treble side, clear and detailed
I am waiting for Logi bt headset, the audio unit will not be used (I don't have ipod), I heard the headset, the sound is pretty good too (not good as plantronics, however), it's said the headband is pretty fragile (I doubt the manufacturer used wrong plastic, it should be made from PE+ABS)
The sound in my HT820 sounds almost like I am listening to a low quality mp3.
There is distortion at certain pitches.

Motorola HT820 + Trinity

Would the Motorola HT820 headphones work on Trinity?
They're working fine for me; the only tweak I did was to disable the JointStereo so I have proper stereo audio - there are a million threads about that around here, it's in the registry.
I have the SYN0948D model of the HT820, which I think is the newest, for previous ones there's a flash firmware update that may fix some skipping.
oh! Mind answering some questions for me?
How are they for music? Sound good? Any major problems? I use TCPMP for music.... will the controls work that are on the headphones themselves? How about the battery life (of the phone and the headphones?).
It seems the headphones also have a mic? Does that work with the phone?
Id appreciate if you could answer these for me... thanks!
The sound quality for music is certainly not what I'd call perfect.
Put it this way: I attached them using the supplied 2.5 -> 3.5 mil connector to my high-end audio card in my PC, and they sounded pretty good for headphones of their size.
However, when running over Bluetooth there is a noticeable drop in audio fidelity. I don't know whether to attribute that to the Trinity or to the headphones, but I suspect the Trinity. Maybe it's downmixing the audio?
There is a lot of A2DP tweaking you can do to find the best balance between audio quality and skipping/reception; I left it fairly close to the defaults for now, and I'll probably play with it more later.
The mic works with the phone and the audio quality for voice calling is outstanding. It sure makes a difference to hear a person in both ears - when I use them I almost never have to ask a person to repeat themselves. I haven't heard what anyone else sounds like when calling from the Ht820s, but friends say that they can hear a slight echo depending on the room I'm in. Makes sense because the room I usually call from is a smallish office/den with wood floors and lots of echoes.
I am going to fire up TCPMP right now to try to play a song with it. I've been using PocketMusic but it sucks balls...
Plays the song just fine, but it doesn't seem to support the next/prev track buttons at all. I tried to map them in the Hot Keys section, no dice.
PocketMusic and WMP both seem to work with the buttons, for what that's worth.
If you need anything else, just PM me like last time.
Yah I tried pocketmusic... it blows. I use tcpmp for everything. I suppose I can just use the controls on the phone itself.
I currently use the shure buds.... I hope Im not too used to the great quality ive been getting on them.

Music output Quality is Pathetic.. I stand corrected please.

Load Music, connect the earphone and the output sount quality is pathetic/worse even compare to the XDA ATOM/Exec or for that matter any other WM device I owned in past. On the other side the speaker output quality is still OK. The sound through the earphone ecos..sometimeit the voice goes low and instruments are high... normally this happens when you switch on the 3D surround on other devices like samsung Innov8. But the in X1 the quality is worse.. I even took it to the sony service they reloaded the ROM a fresh but the problems still remains. IS IT THE ACCEPTED SOUND QUALITY FROM X1. How about other owners .. do they get better sound output/quality through earphone. Is there anything I am doing wrong, Kindly suggest.
really? i find the music quality more than good enough. what headphones are you using?
The Headphone quality is f*cking good!!! I havn't heard this kinda bass on my I-Mate Jam or HTC TyTN II.
One thing is correct, the quality of the original earpieces is bad.
I got ones from creative. The one that go into you're ear.
The speaker quality..... Don't talk about it. Hate it
I'm using Sennheiser CX400 earphones and the sound quality is actually better than my iPod 5g.

The headphones supplied with this phone are suprisingly high quality ones. I have my own Phillips branded ones however.
Aside from the headphones, I think you issue is with the software you use. I found that WMPlayer is pretty crap when it comes to playing my favourite tracks. I use PocketPlayer and also Pocket Music, which have some very good equaliser functions. They make a big difference.
I also find the sound quality f*cking good!!
I expected the worse because it's a WM device, but it exceeded my expectations. Also using Creative ear-ins (EP-630)
I think there is a bug in the Sony Media Player software that can result in a seemingly poor quality sound output.
I've found that when opening the media player for the first time and playing a track the soundstage of the music sounds like its collapsed (lacking any high end or openess in the stereo image). If you then tap pause and then play again all of a sudden the soundstage opens out and the sound quality is very good.
Since I've turned on the "clicking" noise for screen taps, the above bug doesn't occur so often.
However, if I receive a call whilst listening to music after subsequently hanging up the bug re-appears.
Anyone else getting this?

I have this too, but I don't think the bug is mediapanel related only.
I get this when I use S2P, Wmplayer and the media panel.
Sounds almost like flat mono before I tap pause and then play again..
I don't see this as a huge bug, but it can get annoying.
It depends on the mood I'm in..
can anyone compare the speakerphone to a nokia n73 or n70?
It's definitely weaker than the N73 one.
so much so its sickening or just a tiny bit? how bad are we talking about here :S?
I was expecting this thread to be about the poor speakerphone quality.... which it is. I know of no WM phone with a good speakerphone so I wasn't expecting it to be as good as my N95's. However, music through headphone jack is as good, or perhaps even better than my N95 (not as much background hiss as the N95). I use Shure SE430's (pretty expensive earphones) and I find the music playback to be quite good. I even hook the X1 up to my Logitech Z5500 speakers through the Line-in jack and I can pretty much DJ a party with the phone and it sounds as good as if the songs were being played off my computer. (This is all through the SE Multimedia Panel btw. I get similar results with CorePlayer or Windows Media Player).
The only problem I have with the media panel is I can't receive calls with it open. That may or may not be a plus/minus to some people, but I guess it's ok. When people call me, it goes straight to voicemail. The only way I can receive calls with music playing is to go back to the today screen (with the music still going), which works out ok too, since I hold the end key to lock the phone, which brings it back to the Today screen before locking.
worst audio player?? are you kidding?
sorry, but thats definitly NOT TRUE.
***************************
the x1 has got the best and most powerfull audio out, i`ve tested. (but not compared with n70/73)
i wrote it few days ago in the accessoires threat.
i use the Ultimate Ears Triple.fi 10 Pro Inear
with 3 drivers/speakers per earpiece. (like a 3 way oldschool musik speaker)
i`ve tested my ue10pro headsets with a lot of other mp3 players and mobile phones.
but the X1 is the first player, who can unleash the power to drive the UE 10 pro to there limit....
only my sondcard a creative x-fi has got enough power to blast your ears/tympanic membrane....
the base is unbeleavable! the headset can go down to 10hz. and the high tones are crisp, sharp, clear. but a little
to soft from the middle to the highest frequency. but this could be fixed with the equalizer/audio booster.
if you set the first base frequency to +12 and the second slider to -10, you can formerly 'feel' the extreme deep bases.
you cant beleave, that you are not in a club!
don`t use the x1+ue10 for longer time on maximum power. thats very risky for your ears. trust me.
the only thing is, you have to use coreplayer and calibrate the equalizer.
or use a new custom rom (touch it hd) with integrated audio booster.
holy ****, that rulez!!
Ultimate Ears Triple.fi 10 Pro Inear (~300$-400$)
http://www.ultimateears.com/_ultimat...escription.php
these devices with othoplastic, spezially for your ears. and a laser burns your name into the headsets.
if you have 900$ bucks into your pocket, take a look at that:
http://www.ultimateears.com/_ultimat...escription.php
or 1150$? with 4 audio drivers/speaker per ear!!
http://www.ultimateears.com/_ultimat...escription.php
this is the last headset you buy! the cables are replaceble with translucent cables and iphone button.
no more broken headset cables/wires.
my advice, use coreplayer. DONT adjust the equalizer/tone faders more then 12 db.
you will be surprised.
(core is able to adjust more than 12db/slider. more then 12db will bring disharmonies and ugly subtones and crickeling)
(the audio booster could only adjust 6 db. thats not enough for xtreme bases.
but dont use in coreplayer the 2 lowest faders both to +12. thats to much base and
the headsets and the power amp will be very unprecise and roar/rumble and you run into danger to burn the headset
for good kickbase decrase the lowest fader to -3 and the second fader to +12, the 3th to +6. increase the high tones 1-4 db.
for good ultra deep base drums, set the lowest frequenzy +9 or +12, and the second one to -2, the third 0 db.
i have a ultimate ear fi 5 pro headphones with two driver lower is range then DOMin8or tri fi 10 pro. i get quite good results but not on the default player. I only use touch flo 3d in -built music player with audio booster, if you know how to set it , i guarantee you get better sound then walkman phone. i prefer bass and vocal no to be so dull. get the touch flo 3d music player set it to rock mode first then try to made this mode to v shape by just shifting the first two bar to be same as the last two bar, trust me even if you are using your default headphones, you will notice the difference

speaker phone n95 8gb i think is the best
try this setting on audio booster
possibly, but i will it verify by my own. for me, this is the best combo i`ve tested. and ths x1 has got exactly that power, i`ve searched for. more power will destruct my/your ears
i like this unhealthy power of X1. and at 90% power, the sound is very precise and defined.
and 90% is my personal max. and i like it loud. but 100% ? not with me. *G
audio booster has got other cross over frequencies. so my advice/hint could not used with audio booster. audio booster has a range of +-6 db. thats not as good as cores +-12db(possible +-18, but most time useless. only for spezial noise filtering. for example in microphone recordings)
the most players output power broken down, if i increased the base and at high volume.
with other players, you can formaly feel the missing amp power. (ipod nano iv suuuxxxxxx,cheap no name mp3 player,orbit,diamond,nokia 6233, creative zen v plus. but zen v was the best.(not the best menu, but good sound quali)
but now the x1 is my favorit device)
imho the x1 has got a good power amp.
im not sure will it fit everyone style but after some tunning i think this settings best for me to go for on default earphones, i have been looking for post how to optimized sound quality, here is one, hopefully more will share there experience, i bought the x1 because of the 3.5mm connector if x1 doesnt has it i wont even look up to x1!

Hissing/static noise everytime G1 plays sound. Both speaker and headset. Just me?

I have a noise problem, I don't think it's quite the same as previously posted noise problems.
I get a hissinh/static noise from the phones speaker (on the back) and from headphones. It is only happening while the phone plays sound (and some seconds later). Every time I up or down the sound with the volume keys, there are noise coming out of the speaker for some seconds. Please report if you have the same issue, especially eith headphones.
I could live with the speaker-noise, it's not that big a deal.. What's worse is it is in the headphones. I have a quite low impedance set of in-ear plugs from creative (I am able to hear the hard drive spinning up in my old mp3-player, but no constant noise) Crap. I want to use the phone for music listening. Question is: software or hardware related? Using JF 1.51 ADP for the record
I hope it is hardware related - I bought mine off ebay, allthoug brand new and everything, I don't know how I would go about getting it fixed/a new one with no receipt. Shipping it back and forth to England isn't really tempting either.
It's not just you, it's piss-poor rf isolation on the audio outputs. Listening with bluetooth doesn't solve the issue either as bluetooth has its own noise.
Yeah, I have yet to listen to a decent pair of BT headsets.
So this is a known problem, and it's definitely a HW issue? The fact that it's only there when sound is played, and is also there with a headset (where shielding around connectors is not and should not be a problem at ALL) made me hope this was softwar related. Argh, what to do then? The sound quality despite this seemed prety decent, although a headache today prevents me from really listening to music and say for sure. Shame.
*Pondering refund options.*
Any chance of isolating around the connector and fixing this, if it is "airborne" caused noise, or will the noice enter the equation before the connector (cabling, sound chip)?
I will try with a relatively high impedance headset (sennheiser 555) and see if it is better there. But can't take them on the bus anyway. But a couple of Ωs could always be added somewhere along the cable and might do some good. Have to have the sound at the lowest levels with the in-ears. Maybe a software fix to lower the volume output will help? Or won't it, if RF noise is the cause?
red: I will buy this item and hope it helps. And will look into lowering the volume output when using headphones as well. Should be possible (atleast it usually is with tweaks in WinMo.)

Sound distortion playing music with some headphones

I have found some strange behaviour that i'm hoping someone else can test out on their Galaxy S.
I have found that some headphones seem to work fine with the phone for music playing but others result in the sound being distorted with the vocals being very faint as if the left and right channel are cancelling each other out (with vocals generally being on left and right channel).
The packaged Samsung headphones appear to work properly although the quality seems average. I tried my iPhone headphones but these resulted in the strange sound distortion described above. I also tried a pair of cheap Sennheiser which were a free give away with a purchase from Richer Sounds and they worked well. Another pair of no-name cheap headphones exhibited the same distortion problems as the iPhone headphones.
Oddly, the FM radio sounded ok with all the headphones, it's just the music player that has the problem. I have also tried a couple of other music apps including the doubletwist player to rule out the software.
I'm considering taking it back to the shop to swap for a replacement. I'd be grateful if anyone could try out some headphones (particularly iPhone ones) on their Galaxy S and report their results to see if this is just a quirk with my phone or the Galaxy S in general.
Many Thanks
I just need some clarification because I know that a headset, and not headphones, is delivered with the Iphone. If it was a headset then I might suspect that different Iphones use different polarity as opposed to Samsung. Try out the Samsung headset on the Iphone.
EDIT:
Obviously not the problem. I must have skipped over the radio experience.
I can't post a link to it, but I remembered that GSMArena did a thorough review of the SGS. If you find your way to it, go to page 6 and see the sound chart at the bottom. SGS is superior in sound to iPhone. Perhaps the iPhone headset/headphones and the cheap ones are not sufficient for the SGS? I'm guessing
I had a similar experience when I tried to use the Samsung Spica headset on my HTC Hero. It seems that it might be a difference in polarity as suggested above.
Does all the headsets that give distorted sounds have a microphone on them? (E.g. not headphones)
the iPhone's headphones have extremely high distortion regardless of the media using to play them. The SGS is probably just overpowering them because they are very loud headphones as well/easily powered.
No it's nothing to do with them being overpowered.
I have an expensive pair of etymotic in ear headphones that are exhibiting the very same problem. Strangely I found a fix. They have a microphone on them and pressing in the answer button on them seems to fix the problem. I have taped the button down now and everything works perfectly. The second that button is released though, everything goes back to being faint, muffled and distorted.
Odd!
PS. This isn't just with the music player. I noticed it first watching a video.
It sounds like Samsung has their own way of producing the 3.5mm port with regards to the microphone support.
The Samsung headset distorts music on my HTC Hero.
The HTC headset distorts music on my gfs Galaxy Spica
To be clear, are you saying the problem only affects headsets with microphones? I have etymotic er4p headphones and it would be a deal breaker if they didn't work right with this phone.
If its only showing up in the media player, check that you havent enabled the 5.1 button in the the top right of the player. This can really screw with the sound and entire frequency ranges can be lost. I'm guessing this is whats happening.
The default headphones work fine for me if a little tinny, but with my Senheissers, the results are very pleasing. Apart from a slight gap between tracks that should seemlessly play through, I prefer using it to my iPod Touch. Being able to change tracks and volume without unlocking is a nice feature.
I threw my iPod headphones out years ago, they're the most ridiculous design ever, with the cable tapping the inside sleeve all the time when you walk or run.

It sounds like that the problem is with headsets with microphones, yes. Not sure if it happens with all 3rd party headsets w/ mic though.
Considering you have etymotic, and ClownShoes a few posts up have problems with this brand, I guess you're out of luck unless you wanna tape the answering button like he did.
The er4p is just headphones, so it sounds like i'm in luck.
Got my GS a few days ago and im having exactly the same problem with the Etymotic hf2 Headset with mic. So yeah it looks like it the mic that causes the problems.

It's a little bit crude, but taping the button down does work.
I have the same issue with with Monster Studios even with the cable without the integrated mic. Would be great to have some sort of fix.
Headphone issues
Just thought I would post what I knew about the issue, both me and my dad purchased the same pair of headphones to use on mp3 players (the headphones are ultimate ears metro fi 220 vi's if I remember correctly, these have an in-line microphone as well as a single button for answering calls and to control music playback). Whilst I experienced no distortion when using them on my iPod Classic, my Dad's Creative player would produce the issues described above - he found that either taping the button down or slightly pulling the headphones out would solve the issue however it ended up annoying him so much that he went back to using another set of headphones.
I don't know what causes the issue but I just thought I would let people know
i have some sennsihaur sport headphones which work fine no problems. i also a monster fm transmitter in the car.. again no problesm.. just make sure the volume is not on max but 1 setting below max.
Hmmmm, a few problems here. Obviously the standard Samsung headphones are fine, no humming, no background noise. However if I connect the following:
1. Standard Apple iPhone (with mic) loads of background noise, humming etc
2. Shure (no mic) loads of background noise, humming etc
3. B&O (no mic) loads of background noise, humming etc
4. Shure (with mic adaptor) loads of background noise, humming etc greatly reduced by pressing the mute key.
Using the Shure adaptor with the others resulting in the same as 4.
Needless to say I'm not happy!
That's too bad. Not being able to use my Shure with the phone renders it useless for music and that IS important.
In the SERVICE MODE *#*#197328640#*#* there is an audio menu
there you can change the headset settings too like NR noise reducion.
i did not test and changed the settings but when i had the samsung omnia2 last year
i had some problems with my headset and fix it in in the sevice menu.
when you gonne do some tests write down the orginal settings before you try.
hope this will help some of you..... and post the results
im sure its the jack, cos the galaxy s has a 4pole trrs at left/right/mic/ground
iphone compatible headset have a 4pole trrs at left/right/ground/mic
thats why pressing the mic button clears up the sound as it closes the circuit
so it a matter of finding an adaptor that switches the mic and ground terminals
I have a tf10vi and im trying to diy one
will post the results
Just saw the post and thought I would check mine again, not that I noticed anything....anyway tried few songs and different types and all are sounding amazing, I use Sure 530 so music needs to be no lower than 256 to get the best out of the phones, most of my music tracks are 320bit.
