Audio Quality with a2dp - 8125, K-JAM, P4300, MDA Vario Software Upgrading

I've recently bought a Globalsat BTH-820 for the car to use with my wizard, but I must say that I'm very disappointed in the audio quality. I've tried different roms (I'm running the latest 2.25) as well as different players, with the same results. The audio seems muted with a high pitch distortions that should like whistling.
If anyone has the BTH-820, I'd like to know if they're having the same issues. I'd also like to know the quality of other BT Headsets, especially the clip-on type with a mini-USB charger plug.
I'm probably going to return the unit anyway since it won't stay on while being charged. A stupid design decision which makes the car usage very annoying.
Any Ideas? Which clip-on should I replace it with?

Good Bluetooth headset for Tilt

I've read plenty of threads on here about the bluethooth issue with the tilt/kaiser. I have tried a few bluetooth headsets, but they are not very good at all.. Please give feedback on the models you've used and if is good or not
Aliph Jawbone

I think the Aliph Jawbone is the best by far. Noise cancellation technology that originated in Department of Defense Advanced Research Projects. I have conversations while I'm driving and the other party has no idea that I'm on a cell phone.
Jawbone has received topnotch ratings in every review I've seen.
I absolutely love the motorola s9!
Jabra bt8010 is very good, but volume is low like others
I also recommend the BT8010 -- but wait until the weekend, as Fry's has had half-price weekend deals on the headset a couple times over the last month or so.
If you have Money and you like Cristal Clear Sound ... buy Sony DR-BT50. Its the only Bluetooth Headset with a Semi Profisional DA Converter. It works with 24bit and you hear the different!!!! 17 hours runtime is the next point.

Concur...This is what I use and it works great!
I have the jabra BT620S stereo bluetooth headset...just got it and paired it up this morning...seems to work great, volume can get decent but not as loud as my wired sennheiser, hopefully i can find a bluetooth hack to boost it somehow
I use the S9 and they work great for me. I have a friend that can't stand them, I think it is pretty hit or miss on how they fit your head. Some people love em but I htink if you have average size head you are fine, too big or too small and they don't fit very comfortable.
The battery life on them is fine, I use em a few hours a day and I plug it in once a week with no problems.
The sounds quality is good and volume is ok but not as loud as wired.
the jawbone, is it stero? the one I glanced at only was bluetooth headpeice not a headset. did I find the wrong one?
Thanks for the input so far guys... But I'm looking for more of call volume and being able to hear nice and loud.. I need this more for work and really am not using it for music... I too heard the Jawbone was suppose to be good but the Tilt is bluetooth2.0 and the jawbone only supports 1.2 or something like that.
for some weeks i use this
http://www.accessoryjack.com/servlet/the-570/i.Tech-Clip-Radio-Bluetooth/Detail
and i am very very happy
excellent quality in music listening
good fm receiver
more than 9 hours battery and bl handsfree in one pack
S9 Is great, just bought a Jawbone...charging now
Love my Jawbone.
I have had very bad luck with the Jawbone. They seem quite delicate. I had one fail and a friend also had his fail. In addition, they are terrible in the wind. The other party cannot hear you at all if there is any wind, so use outside is limited at best. If you will only be using it inside, then the Jawbone is OK.
I recently got a BlueAnt Z9. It also has good noise cancellation technology, seems more robust, gets plenty loud even with tht Tilt and does not have big wind problems. Also, BlueAnt is continuing to refine the firmware and provides free update.

I use Plantronics Discovery 665 and it is great. AudioQuality is absolutely amazing. the best I've had so far. For stereo I use Plantronics 590E witch is also very good, but gives a little to much bass i think. That can be fixed by using PocketPlayer 3.51 witch by the way is the best musicplayer I've ever used on a pocketPC.
Just my two cents anyway
Moby
Yes I'm just using this inside with no wind.. I need one with the volume loud enough.. I just got the Jabra bt 8040 and the volume is so low... I will be returning this.. So the jawbone works...? I heard that the jawbone is only bluetooth 1.2 or somehting like that and the Tilt supports bluetooth 2.0.. I just hate having to try out a bunch of different headsets and returning them for another... I use it quite a bit for work, so need one with LOUD volume
BlueAnt Z9
I have a few headset's that I've tried with the Kaiser (running XDA V1.2 w/volume patches). I know I have more in boxes, but these are the ones I could find.
I purchased a BlueAnt Z9 because it runs BT V2.0 and it fits my ear better than the Nokia BH-900. IMHO the Z9 is clearly the better headset for volume on the Kaiser It's a bit tinny to listen to, but I can get the volume very loud with this headset.
I have tried the following 5 headsets:
Nokia BH-900, Wireless - Bluetooth 2.0 EDR, good volume and no cutouts
JawBone, Wireless - Bluetooth 1.2, low volume and background hiss
Motorola HS850, wireless - Bluetooth 1.2, low volume w/hiss
BlueAnt Z9, Wireless - Bluetooth 2.0, good volume, no cutouts
Sony HBH-300, Wireless - Bluetooth 1.1, low volume
My limited experience with headsets seems to show that BT 2.0 headsets function better with the Kaiser the BT 1.x headsets.
Anyone else find this to be true?
I've been using the Plantronics 665 for months and it's great. A friend has used his for over a year. It has good noise cancellation, good volume, and it is very light weight.
I use a Jawbone on my Wizard and now my Tilt. It actually has better sound on my Tilt now, and people I talk to have asked me if I got a new headset when I switched to the Tilt.
The Jawbone is better than the Plantronics 510 I had and the old Jabra 320 (I think, older version of what is now the Jabra 500) for me with sound quality.
I do a LOT of conference calls, and am on the phone for sometimes hours dealing with system issues. The Jawbone has been great. I have even walked out of my office and gone downstairs to the kitchen before I started hearing cutting out and realized I had left my phone upstairs (so the range is great with the Tilt).
YMMV, but I recommend the Jawbone with the Tilt based on my experience.
Jawbone automatic gain?
When I first hooked up my jawbone to my 8525 the first thing I did was turn on the vaccuum and was amazed that it actually did ratchet up the volume. Shortly after that, it simply stopped adjusting. Now on the 8925, no change.
Happy with the jawbone, but it certainly doesn't do well with direct wind though.
My last headset I loved was my Bluetrek G2, comfortable beyond belief! Did fairly well in the wind as well...

Bluetooth solution for my car?

Hey, when I search the forums for bluetooth a2dp I get overloaded with ROM posts.
I really wanted to ask someone here if they use any kind of bluetooth thing to connect to their car and play music.
I've found a couple things thru google, but none got good reviews.
here is 1
http://www.amazon.com/Scosche-motorMOUTH-Bluetooth®-Bluetooth-reception/dp/B001AVSWEE
I don't want voice dialing or anything like that, just something to play music in my car wirelessly.
Help!!
Unless you're willing to pay out the nose for some decent speakers, you're probably better off buying an fm transmitter and using your car speakers.
The problem is there isn't much of a market for what you're wanting, and sometimes its difficult for battery powered speakers to overcome road noise while not destroying sound quality. If you're bent on this notion though, take a look in outdoor wireless speakers. They will most likely not only be cheaper but have more oomph in them than a "car" bluetooth speaker.

Why don't you post what type of car and what type of car radio you have to begin with? Best route to go is to get an addon that is specific to your radio, or buy a new head unit all together that includes BT built in.
This is what I've been looking at: http://www.amazon.com/Kensington-LiquidAUX-Bluetooth-Remote-Phones/dp/B0011UIX2K/ref=sr_1_12?ie=UTF8&s=wireless&qid=1278794237&sr=8-12
Can anyone say how the sound quality of A2DP really is? Is it equal to the line out?
I did a search, because I was curious myself on what you could use and I found something on ebay that may be worth looking into.
For the price, you can answer calls and you can stream your music as well from what it says.

I have a 2007 scion tc with the stock radio. The car has a power port, ipod dock and a line in aux port inside the center console. I usually run the line from my phone in the dock to the line in port. I can power a bluetooth receiver from inside my console, so I would really just want a receiver if it sounds good. Fm receivers sound horrible, hoping that a2dp sounds better.

I was looking at that as well, I might get it. I also would like to know the sound quality of a2dp.
Thanks everyone for the help and replies!
Man I miss my TC, I loved that car..... Anyway, I find the quality is good for being wireless. I guess it could always be better I would rather use a cable, but you cant beat wireless streaming. I like that device pardonmyfreedom posted about, think I will def get one of those.

I would stay away from FM transmitters for streaming music...****ty quality. Often sounds muffled and distorted not to mention inconsistent. Often switching between channels to find the best quality and then five mins it sounds like hell again...
My 2007 Prius has a line-in jack right next to a 12V DC input in the center console. I've tried numerous solutions, figuring that anything I use will be nicely hidden away in the center console. Unfortunately it seems that anything you plug into 12V DC will give you horrendous sound.
I have not gone so far as to find and try out something that is powered off AA batteries, but it would be an interesting test to show whether or not the DC adapter is what's killing sound quality.
For reference, I tried the Nexus One multimedia desktop dock (when I had an N1) and a Belkin unit which I should have known better as anything with the Belkin name on it sucks.
The other issue for me is that even if the sound was crystal clear and perfect, Android 2.1 (and I'm willing to bet 2.2 as well) will not auto-connect to A2DP. Only headset or hands free profiles. So I'd end up spending a minute getting the thing setup before even going anywhere. Too much hassle for anything but a 30+ minute drive.
FWIW, I have the Kensington LiquidAUX Bluetooth Car Kit.
2007 Honda Element, Aux/12V plug on the passenger side dashboard (roughly 4 feet away).
See: Amazon.com: Kensington LiquidAUX Bluetooth Car Kit with Remote for Music Phones: Cell Phones & Service
MP3 and music audio sounds pretty clear, though audiophiles will be disappointed. I'm used to listening to internet radio and satellite radio, so audio quality only needs to not hiss and pop for me to be happy. Besides, my car has a boat load of road noise, so no biggie.
Call quality sounds crisp for the incoming portion, as in I can hear the other party loud and clear. Unfortunately, the other party has a hard time hearing me. If you know what the speaker phone gives the other party in terms of call quality, imagine it being SLIGHTLY softer sounding to them. So, I can hear them perfectly fine, but they have a slightly harder time hearing me (compared to me being on speakerphone, and they on regular headset). Being closer to the microphone doesn't improve anything, and I could be 1 foot from the microphone or 5 feet from the microphone. It sounds the same to them regardless. They describe me as sounding muffled. Speakerphone already sounds muffled, and bluetooth with the Kensington sounds softer and still muffled.
The remote is a nifty feature, too. It controls the native audio player for play/pause/fwd/rwd. It also controls Slacker for play/pause/skip. AWESOME! Voice dialing doesn't work (though I hope FroYo fixes this).
Overall, I'm happy with the product and will use it while driving and simply speak a bit louder and slower while on the phone. Maybe FroYo will improve call quality enough to make this a better headset, but at least it's great for bluetooth audio playback.
Sorry, no pictures as of yet, because it's dark. I'll try to remember to take some tomorrow.

motorokr t505 FTW.
Looked around with no luck. Was wondering if there are any reports of the OTA leak solving some of the BT issues.
+1 for the Motorola T505. I've been using mine for well over a year, and I love it.
Here are some photos of the Kensington LiquidAUX

I have a Arkon car dock. Could I plug in my Liquid AUX in my cig lighter under my arm rest, and just dock my car with my ARKON car dock?
I have the one just like the one from ebay. Very happy with it just a few limitations, the bt has to be connected manually reach time
Pause and play don't work on all apps. Volume had to be down a little on the phone to get it to stop over saturation. But then its clear, loud pauses when in a call (have a plantronics975 for the phone)

It's very good. No difference between it and the line out directly.
I just removed the "calling" part of it so I could keep a bluetooth headset (for calling - plantronics pro) from the bluetooth profile - works perfectly.
-D
Yeah, I got the liquid aux one and disabled the phone part too. I use tasker with it to turn bluetooth on automatically when I pop it into the car mount. I am loving the bluetooth sound, same as line in.

Anyone know of a widget or some other way for my phone to connect to my bluetooth? It doesn't connect every time, I have to dig into the settings and connect manually 50% of the time.

I have the LiquidAUX installed in my Z. For some extra punch, I also installed a Boostaroo between the LiquidAUX and my Sat Input. I think the audio quality is quite good. However, My ears aint what they used to be, and I do have a really nice BOSE system in the Z, so those two factors have to be considered.
The LiquidAUX connects to my DInc as soon as I start the car, so it seems well integrated. The only manual step I have is to launch Slacker, which I listen to exclusively.
One thing that needs to be fixed is, when I initiate a call via bluetooth, Slacker is not automatically muted, so the music really screws up the voice recognition. I have to pause Slacker before I initiate the call. I'm sure this will be fixed at some point, seeing how voice dialing just started working with 2.2.
All in all, I'm pretty please with how this setup works, and I have no issues with audio quality.

Headphone Interference

I've noticed whilst gaming on the train using my HD7, I sometimes get interference in my headphones. It sounds like mobile static (dit dit-dit-dit etc).
Does this happen on all HD7's (maybe when reception is fluctuating)? I would be very interested to hear whether this happens (or not) from other HD7 owners. Thanks!
Any long conductor is susceptible to radio-frequency interference. In fact, headphone cables are so susceptible to it that your phone uses the cable as an aerial for FM radio reception!
Personally I use bluetooth headphones so don't get the problem. It does mean I can't use the FM Radio function but to be honest I can't say I miss it. On the plus side, I get hands-free calling all the time.
I have that same problem with my speakers whenever im getting a call or text on any phone that is on my table my speakers start to make noise 2-3 seconds before the phone starts ringing.
but ive never had that problem with headphones.

Whenever im using my Bluetooth headphones and pass through a scanner like the ones at libraries or airports my headphones start to make a high frequency noise.
I just got my HD7 as a replacement for my Venue Pro and am hearing the interference in my headphones that I've never had on any other phone.
It sounds like what my computer speakers would sound like when I had Nextel and a call would be coming in. I only notice this between songs.

[Q] in car integration & OHM problem

hello, I did this stuff here Alfa Romeo & Galaxy Tab integrating seamless the tab and my dashboard.
The overall result is very good, except for the audio volume, and being not an audio expert I fear that this is an impedence problem.
To make it very short, I just connected the headphone plug with the inputs of a 50W ("rms", real 50 watts they say, not fake 50w as standard OEM car audio), a kenwood KTP-500 thing. The problem is that the max volume is VERY VERY low in comparison to whatever oem standard ****ty car audio device, and that is quite impossible to me, and also for audio tuning shop owners I enquired for some advice.
So I think I need to convert, somehow, the signal to be good for the amplifier.
The amplifier has got switch between "low gain and high gain" but it does not change that much.
So I've got 2 plans to get an at least "normal" audio volume, amplifying the signal with some kind of "line amplifier", or find a guy (perhaps here? ) who can explain me the setup error, so that I can fix it. Shouln't be that difficult, but I'm ignorant in this stuff, and surprisingly, neither do know the people that works at kenwood/alpine/whateverBlingBling-audio shops in my city.
I also tried to debug my installation connecting a PSP, some other phones, a small television, an old cd player... all with the same low-volume result. So it's not a GalaxyTab (p1000, the good 'ol one, since it's exactly 2din fit) issue, but more general, having knowledge in audio signals may help...
So what is the point with connecting directly an earphone jack to the inputs of an amplifier? It's so amazing after 1 year having the tab as audio unit, it's a shame to have this volume issue è__é thanks for any clue
p.s. the audio quality is excellent, anyway, no buzz, humming or distortion. It's only... too low
I have the same problem, the volume is very very low, especially in a telephone conversation using speakers. However the sound quality is excellent. The problem is that you can not have a conversation without a headset ,when youare in a opne place.

[Q] Audio and video out of synch when using Bluetooth - any suggestions?

Hello all.
I'm having problems with Bluetooth on my One. The device that I'm trying to use with it is called a Siemens MiniTek. (It's actually a hearing-aid accessory. You clip to the front of your shirt - it looks a bit like an MP3 player - and it plus my hearing aids together then function like a Bluetooth headset. So, when making a call, the sound is sent wirelessly to the hearing aids, and the device itself has a microphone on it.)
Making a call with it works okay; but if I try to use it to get audio out of my One in other conditions (playing a game, say, or watching downloaded video) then the video and audio are always badly out of synch - the sound lags at least one second behind the picture.
I'm using the stock HTC ROM, the latest one available in the UK (2.24.401.8).
Anyone have any thoughts as to why this might be happening and what I can do about it?
Mby there is too much data to deliver via bluetooth (high quality audi/video sound) and the hearing aid device is not meant to recive such a load.
When calling to some1, the sound quality is only like 24kbps or something.
Just a thought

That might result in there either being no sound at all or in the sound quality being very poor, but I don't see that it would result in reasonable-quality sound running 1 second behind the picture...?
The device itself is designed to handle fairly high quality sound: as well as receiving Bluetooth signals it can take analogue audio input via a 2.5mm stereo jack socket, and it also has a separate "base station" transmitter which you can plug into (say) the headphone socket of your TV: the transmitter then sends a signal wirelessly to the MiniTek (using a proprietary version of Bluetooth) and the MiniTek relays it to the hearing aids. Using either the direct-line input or the wireless transmitter works quite nicely, and there's no perceptible lag problem there.
I should have said, I've been onto Siemens tech support about it, and they're adamant that it shouldn't be doing this, and they don't know why it is. So I'm looking for a problem at the phone end.

i've experienced the same issues on various BT-Receivers and Smartphones. Seems to be a general issue. So far, this 1 second lag was present on all combinations of:
Phones: Samsung Galaxy S2 / iPhone 4 / HTC One
Receivers: Creative D100 / Creative D200 / Belkin BT Adapter
As i found out so far, this problem occours when the receiver can't handle the apt-x codec and audio has to be resampled to the older SBC codec. Found one thread kinda dealing with this topic, but haven't tried it out for myself at the moment. I'll do some testing later when i'm at home.
