Bluetooth audio quality concerns

OK, I'm opening a new thread with this one, since I would really like to gather opinions of people who are also facing bluetooth audio quality issues.

Since I got my iPhone 3G, and paired it with my bluetooth headsets, people have been complaining that the couldn't hear me well. My voice would crack up, or even not make it at all to the other side. I got a couple of new bluetooth headsets, only to find out that it wasn't the headsets' fault. That said, I would like to add, that all the headsets that seem to misbehave when paired to the iPhone, work great when in use with my older SE mobile phone.

I did some testing and found out that, the issue of my side cracking up or not sounding at all would only arise when the OTHER party was in a noisy environment (usually trying to talk to somebody in a Mall would do the trick). That said, I would also like to add that when talking through the iPhone itself (even on speakerphone), would work fine!

I am suspecting that there is an echo cancelation feature build-into the iPhone that revs up when talking through a bluetooth headset and seems to cut-off my headset's input level when strong noise it detected from the other side, presumably to avoid echo. Seems like this feature is badly tuned, in a way that communication can no longer work in an syncronous way.

What seems strange to me is that, after updating to v2.2 of iPhone software, the issue seemed to have gone away; however, it looks like it's back!

This whole situation could also be connected to various bluetooth quality issues many people are facing when using bluetooth car kits. I would suggest you try and connect such issues with the NOISE on the OTHER END.

Any input would be greatly appreciated.

P.S. I will try and put together a Skype call that would hopefully demostrate what I am trying to say.

iPhone 3G v2.2

Hi,

I asked the Plantronics support to determine whether their engineering are actively working with Apple on this issue and here is their response:

---start---
I asked my engineering contact about your question, and he confirmed that Plantronics and Apple and continually talking. This is all he said.
---end---

You will understand that due to NDA reasons, they could not provide me with more details.

Apple wants to make the iPhone a business mobile ? So I hope now that they will really fix this issue to make this mobile a bit closer to a business mobile.

Regards

Well, I'll join the list. I have a 3 week old 3Gs and two 'original' Jawbone headsets and the volume is always too low when making calls. I can turn the volume up but have to do this every time I make a call!! This was never a problem with my Sony Ericsson P1i with the same headsets.

If there was a fix for this I would be one happy bunny!!

Thanks.

You can add me to the list as well. Got my Iphone 3GS two weeks ago and have tried my moto h670 and apple headset and with both people complain they cant hear me. After having the phone 4 days I went to the apple store about the problem and they replaced the phone only to have the problem get worse. I drive for a living and must have BT so if this doesnt get fixed my phone will have to go and I will go back to my pearl which worked perfect.

Hi, sorry for the long text, but want to share the text I've been bombarding Apple support with, but can only send as 'feedback', to which they never respond, of course. Chased Apple in Sweden today via phone, and guess what, they could at first hardly hear what I said as I used my BT headset with poor sound quality...case in point! Anyway, seriously, after a 20min long conversation they could in the end only say that the iPhone BT HFP profile is "not compatible with my headset".. they just wanted to get rid of me.

Text sent to Apple: --------------------------------------------------
Problem: iPhone – non-Apple BT headsets interworking
Background FACTS:
- BT has been around several years and is designed for multivendor interworking
- Many other vendors headseats interwork OK with mobiles from many other vendors
- When iPhones entered the market many users started to have problems
I cannot accept a standard response about iPhone being BT compliant – just look around you in the marketplace and you’ll understand why!

My iPhone 3Gs 3.1.2 symptoms:
1. good A2DP sound, only that next/prev in AVRCP doesn’t work (=acceptable…)
2. handsfree at phone calls intermittently/periodically:
- poor sound quality, cracking up
- disconnected mid-call
- at switch handsfree <-> speakers, sound sent to iPhone speaker but in parallel very loud static noise to headset! THIS fact alone clearly suggests a conflict within iPhone OS/firmware!
3. Headset SE HBH-DS980 tested OK with several non-SE/non-iPhone mobiles
4. Other headsets (Jabra etc) tested with iPhone -> same problem

You can not claim all other vendors are wrong and Apple is right about BT interworking. Besides, this is likely an internal iPhone problem not necessarily related to BT technology as such.

If you want me to try out different solutions I'd be glad to do so, but please treat this with some level of professionalism and don't just ignore it. Without fixing this, iPhone is NOT a business phone.

Failing the above, I will bring this to the attention of our industry media, though I do not want to resort to such measures.

Just tried something that seem to help for me. These are the steps I did. Make a call using bt while still in the call switch audio source to handset then switch back to bt. When I do this volume seems to double and people say they can hear me better. I only have to do this once until I turn my headset off and back on again and I also tried with 4 different brands and this seems to work. Can other people try this as well and post your results.

Well we are tired of trying different ways for making this work.
Testing and testing and testing...one more time if I hear from someone that he doesn't hear me while I'm testing a new way to make my headset work and I'm gonna smash my device on a wall :P
Had enough of those, what we seek for is a permanent solution.
Things look hopeful , if i take in concern the last posts.
If the new update won't fix it I will seek for another device, although I love my Iphone :/

Oh my god..... This thread has turned my life over. I've had a 3G phone for 17 months. I am currently on my 4th BT headset. I was ****-bent on the BT-stack ofcourse was working in the phone. So naturally I was sure that I was just having bad luck when choosing headsets. I tried, and discarded headsets from Sennheiser, Samsung, Jabra, Aliph and was on the verge of trashing my brand new Plantronics Voyager Pro. I was starting to think I was aurally challenged, and I am actually having my hearing checked professionally in a few days...

I cannot begin to describe my anguish over this issue... I use the phone 2-3 hours per day (effective time) in varying environments, office space, in car, in aeroports etc. I have tried using wired headsets, but after a couple of weeks I end up ripping the cord one way or the other.

To find out you guys described my problem exactly renders both relief as well as blind rage against Apple for not acknowledging this as a flaw in their product (I really dont care if it's S/W or H/W based).

Money is not an issue, if there was a working BT headset that cost $600 and solved the problem I would buy it in a blink of an eye.

At least now I have decided to demote my iPhone to a iPod Touch, I will use it at how as a fun toy to download handheld applications to. In the meantime I am using my daughters pink (that's right... PINK) samsung cheapo-phone as my professional means of communication. And finally ppl keep repeating how nice it is that they can hear me talking again...

Thanks guys for helping me out of my misery...

Posts like yours confirm my firm belief that most of the people are actually unaware that this clearly an Apple issue. Well if they do not intent to inform the world about it then we may take some extreme measures. A facebook group will come as handy.
Just to let the everyday user who doesn't google his every technological problem, to understand why he can't use a **** BT headset with his iPhone...
