HTC Car StereoClip (Aux) Audio Bridge (CAR A100)

Hey all
I just ordered this clip and am excited to get it. I am just wondering if any of you geniuses can add the software to our Sensations to support the aptX audio enhancement CODEC?

Premium music for those on the go
Wirelessly stream music from your HTC phone through your car stereo speakers with the Car StereoClip (Aux). Just plug the adaptor into a 3.5mm auxiliary port, and listen to premium, authentic sound thanks to embedded apt-X enhancement.

Are you on Sense 3.6 or 4.0? Either way you should let us know how it works w/ your sensation.
Maybe that's why we're having BT issues on 4.0 ports... the new codec? meh, just a random thought.

I am on Android Revolution HD 6.6.3 XE so Sense 3.6
The Stereo clip should be shipping at the end of this month.

I'm very excited for this! I've been looking for a good adapter for AGES! I was about to buy a bluetooth adapter to a headphone jack to stream my phone audio to the car stereo via bluetooth to headphone jack. But this looks perfect and reliable. Hopefully it'll work out

Just wanted to add that this dongle has an imbedded battery (6-8 hour estimated), with a micro USB charging port.
I hope to be able to hide this away in my car, and run continuous power to it so I don't have to take it back out again. Hopefully some reviews with good info come out

Since it's a Bluetooth adapter, would it work with other phones via A2DP? Or does it work specifically with HTC phones using a proprietary connection/codec (aptx)?

The way I understand it is that it'll work on either.

Hey all, well the HTC Car StereoClip came in today. I am very pleased, it works just like advertised. It lets me connect via Bluetooth to the clip and play Music thru to my car stereo. When a call comes in it defaults to regular phone earpeice mode and does not try to play the phone call thru bluetooth.
First quick impressions, audio quality is fine. What I am really wondering is would audio quality really jump up in quality if we had the aptX audio enhancement CODEC in the Sensation?

Have you used an auxillary cable to play audio through your car stereo before using the clip? If so, how would you say the audio quality compares?
I currently use an aux cable to play music through my stock stereo on my TSX but the quality is pretty mediocre...

OK, so I guess that means that the phone (One X in my case) can't connect to both this device AND my bluetooth built-in car kit - one for streaming music and one for phone calls?
My car (BMW) has a factory Bluetooth kit installed but, unfortunately, it doesn't support music streaming. I have been using a cable to connect my phone's head phone socket to the AUX-in port of the car and this has been working fine. Music streams via the cable and get's muted when a call comes in via the Bluetooth kit and then un-muted when the call finishes.
I was hoping to pair my phone to both Bluetooth devices and have them working simultaneously, one for music output and the other for phone calls.
Too much to ask for?

Software fix?
...When a call comes in it defaults to regular phone earpeice mode and does not try to play the phone call thru bluetooth...
It really quite stupid that you can't also use this devise for phone calls. When a call comes in, it should remain using the BT. I wander if there is a way to make it work? Perhaps some sort of software or app or something to make this happen...

I guess thats why they also sell the car mic (v100) as a separate piece to the car accessories stuff.
I have both on order, but both are in backorder. Expansys.usa for the car mic and sprint.com for the stereo clip. I'll let you all know how it all works together.

Can you confirm that indeed call does not come through even when there is only a single device pared (mobile and A100)? That would really be shame as this might have been the perfect solution for hands free calling, having mic from the phone for outgoing audio and car speakers for incoming audio.

The easiest way to tell is just to look at the bluetooth pairing settings for the stereoclip, is it just pairable as a media device, or media as well as phone?

Hey All
Ok I wanted to give an update. I am extremely please with StereoClip.
My car is a 2005 Cadillac STS with Nav and factory Blue-tooth for phone but does NOT support Blue-tooth Audio. So I have had to use the AUX in for Pandora until now. The stereo is the factory 15 speaker BOSE system plus a Kicker 10" sub in a custom fiberglass enclosure with its own 1,000 watt amp.
Tonight I just compared the sound quality of Blue-tooth vrs being wired/plugged in. I was nicely surprised that I could not tell a bit of difference in quality. This was done parked in my garage with the car on. I listened to Jazz, Rap, Latin, and Techno. I listened for bass quality, highs, openness, and to my surprise I could not truly tell how I was connected. I was positive that being connect via blue-tooth I was NOT going to get the same sound quality, that I would give up some quality for convenience. Well at least in my 15 min quick test of starting a song listening to it for a min or so then switching how its connected to the car stereo and continuing the song I could not hear any difference. Very happily surprised.
Then I drove for dinner and decided to see if my phone would also pair to my car at a blue-tooth cell phone at the same time will listening to music and it did. My Sensation was paired to the HTC StereoClip and to the Cadillac at the same time. I made a phone call, Pandora paused, The call connected I spoke for a min or two then hung up and then Pandora resumed. All worked perfectly.
So the StereoClip works perfectly. I'm thrilled.
Thanks HTC.
P.S. the only little annoying thing is, for me to pair to it I have to actually press the pairing butting on the StereoClip and then tell my Sensation to connect to it. So its two additional steps I need to do EVERY TIME I get in my car. Kinda a hassle but I feel its better than seeing a wire and being hard wired to the car....

I'm glad you like it! I'm curious of what ROM you are using right now. And would you mind testing it on AOSP based ROM??

Please see attached screen shot to see the exact ROM.
I just rooted my phone (any phone) for the first time several weeks ago. I am extremely please with how my phone works. Someone asked if I could try a different ROM, honestly I'm a believer if it works don't fix it, so I really don't wish to mess with a new ROM for now. So sorry.
Jerry

Got my Stereo Clip in today
And I must say is very nice! I use to use the aux cable to connect the phone to the head unit but with this lil puppy its just bad a$$!
My setup:
I have a BlueAnt S4 (on sale btw on dailysteals.com for 20 bux in the USA I think, sorry!) and that plays media through its speaker. So all my navi voice prompts can be heard through the S4. And the profile the S4 supports is phone audio of course and media audio.
Now I introduce the HTC Car A100. Pairing was easy peasy. Then jumped in the truck to see how this works. I pulled up poweramp and started a track. Then turned on the bluetooth on the phone. Now both the S4 and A100 is connected to the phone. However when connected the music started playing though the S4.
I then went into the bluetooth profile of the BlueAnt S4 and unchecked the media profile. This will then in turn only be used for phone calls only, which works because the A100 cannot play the calls through the speakers. I restarted the track and viola, the music started to stream smooth as silk through my speakers. And it's nothing like the FM transmitters for ipods, this is clear as my aux cable!
I have to say I have not received a call yet with both running. I'll report back on how this functions in my setup. I hope it works lol...

Neo M1 (4.2.2) Sound/Music Issue

Hi Guys,
Bit of weird one here!
I've just bought a Neo M1 (http://www.neomobile.me/neo-m1-feature)
It really is an amzing device for the price but support is non existent and as its a new device there arent many forums/discussions available. My issues seems to be more Android/OS based (i think) so hoping someone can help.
When playing music through speakers with the 3.5mm jack its fine, perfect. But when using earphones, and ive tried many, the music sounds like its is muffled or playing certain channels only. Vocals are low, effects are high and it not useable. Ive tried diffrerent music players and equalizers but nothing is working! Has anybody ever heard of this? Surely if it can play fine thorugh speakers it should be able to via ear/headphones?
Thanks in advance for any ideas!!
Sanders.

have you checked to see if contacts are aligned properly?

I had the opposite effect on the iPod classic: with earphones/headphones, ok; thru jack connected to speaker/amp: muffled, distorted sound.
So had to use the Apple plug (wide plug connected at bottom) to connect to speaker/amp.
I guess it may be something to do with the impedance of the phone.
Would be interesting to know if others report the same issue, before I buy this phone.

How's the Bluetooth with S7 (Tmo)? Issues with Senn Momentum 2 Wireless headphones

Since my usual Bluetooth headphones (V-MODA Crossfade Wireless) sounds terrible on the S7 due to the lack of aptX in the headphones, I picked up the Sennheiser Momentum 2 AEBT Bluetooth headphones. They're very highly reviewed despite issues early on with the Bluetooth; I've confirmed I have the revised version that fixes that.
But if I go outside with my S7 in a pocket, jacket or jeans, the Bluetooth audio cuts in and out. If I hold the phone in my hand or keep it on my belt clip, it usually sounds fine, but sometimes even a slight wind will cause a hiccup. I'm tempted to blame this on the headphones, because even though the V-MODAs sound terrible, they don't skip when the S7 is in my pocket. I know this can sometimes be attributed to your body causing interference, or the numerous wireless transmissions happening outside.
I'm wondering if anyone else has the Sennheiser Momentum 2 and can shed some light on this. Experience with other Bluetooth headphones would be helpful, too. Thanks.

Yup, I've had some issues with it disconnecting in my car as well.

I really hope it's not because of a lame Bluetooth chip in the S7. I like the phone otherwise and would like a really good pair of Bluetooth headphones that I can also wire to my computer at work.

Not sure if aptX will fix it but the sound through bluetooth is just bad. Bad... Crackles and static noises on the high tones etc. Both in my car and on a pair of Bose Soundlink 2. I know it's the S7 fault, didn't have any issues on the iPhone 6. And my Zenbook makes clear sound on the Bose aswell. Through the jack it sounds pretty good but volume should be higher.
Didn't have any disconnection issues tho!
Not sure if this is the same for the Exynos version but the SD820 doesn't support AptX HD in the S7, only 16-bit.
Lots of edits here but I have a pair of Philips Fidelio M2 with AptX support and the crackling and static noises are gone in these. Sounds pretty damn good but these headphones makes my ears hurt after a little while. OnEar

I have the Exynos variant, I can confirm that the Exynos variant can play 24-bit audio at 192Khz, it have the Cirrus Logic CS47L91 (Cirrus Logic is the company who bought Wolfson Microelectronics).

Yeah, I know the aptX here is only SD - I was tempted to get the G5 to get aptX HD but LG's issues with the G4 + the lukewarm early reviews kept me away. I didn't have issues using my other BT phones with the S7, and the Momentums generally work well - if I'm inside.

You've got crappy BT headphones.
My Sony SBH20 doesn't skip a beat or suffer from static and gets great range.
I'm usually in the next room before it starts to lose signal, although I have been able to walk upstairs and keep a solid connection a few times. Doesn't matter if the phone is in my pocket, my bag, the car, or the couch.
If I cover the receiver with my arm or my toddler, then it starts to cut in and out.
And that's only a $40 Cdn dongle.

I am having the same issue with my Verizon s7 edge and my lg tone ultras. The sound is absolutely horrible! A tone of static and distortion, the volume buttons don't work, and it seems the phone is not picking up that they are headphones because I cannot get the UHQ upscaler to not be greyed out. They work great with my wifes Note 5, but not my s7. The weird thing is call audio is perfectly fine, but media audio is horrible.

How about outside? My problems occur outside in NYC, so whether it's being outdoors, the amount of wireless activity in the area, or having my phone in my pocket, something caused the issue. The Momentums sound great otherwise.

I was looking into the new Infinim model that just came out. I can't say I know about the UHQ upscaler, but I thought that was causing static through the speakers on some phones? The rest is a bit puzzling, have you been able to try with a different pair of Bluetooth headphones?

Inside, outside walking, riding the bus, driving the car, sleeping in bed, the BT connection is solid.
Daughter "misplaced" the other BT dongle, the one that supports Apt-X, so only have experience with the one dongle.
But have plugged two different sets of headphones into the Sony dongle with identical results.
This is with the Telus S7, using the Exynos SoC.

I've been having this issue pop up again. I'll be driving in my Mercedes and it just disconnects. I've tried to re-pair, but still does it. I know it's not my car.

I have the galaxy s7 edge with exynos and some Momentum wireless 2 headphones, and I have the exact same problem. I got someone at work to test the headphones with their iphone, and that worked fine.
Edit:
I walked the same route to work with a xperia z5 compact instead of my s7 today. And i had no problems at all. the sound is also much clearer with the z5.
I wonder if the s7 even uses aptx.

Now my headphones are disconnecting sometimes when I'm indoors. Really frustrating. Starting to wonder whether it's the S7, perhaps I'll swap it for another one and see if there's any difference. I really like the phone otherwise and there's nothing out right now that interests me.

I'm having the skipping issue as well with my S7 coupled with the Sony SBH70 Headset and it's bloody annoying

I have Plantronics Headphones that worked great with my S4.
With the S7 I also get crackles and skips when I put the phone in my pants pocket and walk down the street which is a real bummer. The sound quality is fine and it really only seems to happen when I put them in a pants pocket. This did not happen at all with my S4.
The other issue I am getting a lot of (but I dont know if this is the BT or some settings issues) is that I will be on a phone call using a bluetooth headset and then suddenly...nothing. When I take out my phone and look I will see that the BT just disconnected - call still ongoing but seemingly random BT disconnects on calls. VERY FRUSTRATING.

Hi
Hi, I 've just bought a samsung level u pro anc and I'm facing the same problem with my samsung galaxy s7 duos.
when I'm listening a song it cuts out in some parts and it's really annoying.

I hope we can find a fix

Bluetooth audio quality

I have an MTCB joying unit. My opinion is that the Bluetooth audio is absolutely atrocious. I have tried all the various suggestions, but nothing really works.
Can anyone comment on the MTCD units, with respect to Bluetooth audio performance? Specifically, the outgoing call quality (how we sound to the person on the other end).
I would really appreciate an opinion from someone who has witnessed the issues on the MTCB units.
Thank you

No experience with MTCB units here, but audio quality through Bluetooth (at least in regards to music) isn't all that great. 320kbps mp3s sound almost like they are being transcoded on-the-fly to something ~96kbps. Haven't really used the phone, so can't comment there.

Never understood why using files via bluetooth from my phone. Files on SD Card and all sounds great

Convenience. SD cards have to be removed/updated with new files. Not having internet in the car means that playing music downloaded on phone via Apple Music through Bluetooth would be great if it sounded good.

I can chime in on this somewhat. I came from an old Pumpkin brand rockchip on lollipop, bluetooth was the biggest joke on that thing, 100% unusable it may as well not have existed, microphone quality was inaudible junk to the caller.
I have now upgraded to the new Joying brand Intel Sofia 2GB ram unit, which has Bluetooth 4.0 vs the 3.1 on the MTCB unit. The difference is night and day, when using it for hands free calling the quality is great (has some minor road noise like expected) but its 100% usable. For Music streaming, I never had quality issues for music streaming on the MTCB, however I can tell you the Bluetooth 4.0 intel unit plays/sounds perfect, is MUCH more responsive when skipping tracks or pausing or anything, and has the added benefit of displaying song tite/artist, where Bluetooth 3.1 did not support this.
Edit: Also in the caraudiosettings, there is adjustments for bluetooth mic you can make to fit your needs, high sensitivity, medium sensitivity and low sensitivity on the intel unit.

Does the new intel sofia unit show album art through Bluetooth?
Do you use Bluetooth tethering (if you use an Android smartphone)? If so, how is stability and speed?

Yes, you should try it. It should drain less battery, although speed won't be the same.

I have a MTCD Joying VL130 and upstream audio to the other party is quite ok. No difference between internal and external mic.
What I don't like is the fact that downstream audio is only put on the right speaker. This is by design according to Joying support guys. It should reduce the uplink echo...hmm.

So, i have MTCD KD version, and sound realy bad. Idk why

Bluetooth Issues
I have a question with the BT on my unit. I have the external Mic connected and people complain that they can't hear me and they always hang up me. Music works fine but on phone call I have to switch my phone to Speaker. Would disconnecting the external Mic would improve the call quality. Do you suggest I get another external microphone? If you do can you please link me to a good one. Please see the picture for my unit's information.

Bluetooth audio/music quality is a joke on my Witson PX5 unit (MX). Sounds like playing a really old cassette tape.

Very bad sound quality via earphones

Hi, I using Mix 2s and the quality of sound on earphones is quite a disaster.
Sound is very grainy and there is a lot of static noise in some songs. I am using Spotify Premium with very high-quality settings and the sound on wireless and wired earphones is the same - means very bad. So, it’s not just bad piece of set.
I was blaming the audio codec on Bluetooth as my BT earphones should be able to use ACC codec, but there is just SBC available in developer option. I heard the BT codec issue in last Global MIUI I am using global 10.2.2) not allowing to use any codec outside SBC, but the sound is the same on wired earphones.
Does anyone experience the same issue with sound quality?

Thank you, and are you able to connect to BT headseat with any other codec then SBC? I am able to change that in developer option but it always go back to default after leaving menu.

Have tried Mix2s with 3 different phones at home on BT and headset. Samsung A8, Honor 8 Pro and iPhone 6s and most ****ty sound by class is from Xiaomi, which makes me very sad as this is my daily driver... will try MIUI EU if this makes any difference or sell my Xiaomi device.

I come from a redmi note 4X and dont notice any problems with it. I have a brainwavz BLU200, which supports aptx.
Maybe the phone is recognizing the headphones as a headset (for calls which utterly kills the sound quality).

Thank you, but this is not the case. The sound is bad also on wired headphones. Sound is flat, lot of static noise, missing any stage. By class worst sound from 4 phones I can find at home. I will try different USB C to 3.5 mm adapter if helps.

Ouch, I have not tried the usb adapter with my wired headphones. I'm scared to try now (ignorance is bliss?).

My LDAC headphones work well. I am afraid there's something wrong with your device and I'd recommend to have it repaired.

Just tested the wired audio with my Brainwavz HM5 and i found it awesome. Also i have searched a bit on the net and seems that the mi mix 2s outputs analog over the USB-C adapter. The sounds come from the DAC on the SoC (SD845) which seems to be a quite nice DAC (https://semiaccurate.com/2017/12/19/qualcomm-ups-audio-ante-snapdragon-845/) to be a cellphone.
Try wiping and flashing a stock rom. If that dont fix it, I suspect that your case is a hardware problem.
And last but not less important, i'm not an audiophile so maybe what i hear good is subpar to you, but if the sound would be as bad, way more people would have complained by now.

Thank you. I have tried different USB-C to 3,5mm adapter then standard Xiaomi one and grain is about 50% less so positive news here, but sound is still flat and dont have any sound stage. May be I am to picky and got luck with my previous phones. I have ordered external DAC adapter to solve this problem as on the other hand this is only problem I have with the phone.

I one of my friends found the core of the problem. He sad to have iPhone 7 that sounds ****ty as well. He had found out after about year of searching and two sets of headphones that somewhere in some different settings was set MONO sound only. My problem was same and very stupid! For my IQ deffence I don't know why this settings is not located in sound section. So problem solved and thank everybody for help! For anyone having this issue you can deactivate Mono sound in Settings -> Additional Settings -> Accessibility -> Turn off "Mono Audio"
