When I make a call using my bluetooth headset, other people can barely understand me. Often they will hang up because they can't hear me at all. Echo Tests using various applications and the bluetooth headset reveal that my voice is barely audible when speaking into the bluetooth headset. This also affects Voice Dial and anything else that records audio via bluetooth. Testing revealed this to be a phone issue!
As it is, bluetooth calling is UNUSABLE and I urgently depend on being able to drive safely while talking to people. As it stands, this is not possible.
Not an Issue, aka, the following is working fine:
Sony Xperia Z1 C6903
Android Version 4.3
Firmware Build 14.2.A.1.136
Bluetooth Headsets tested:
HTC BH S600
Logitech HS03 V04 (only dug it up to confirm its a phone and not a headset issue)

I found a promising bit of information for the Samsung Galaxy 2, where you could enter a special code and get access to a menu that allows you to set recording volume levels:
Unfortunately it does not work on Sony Xperia phones. But is there really nothing similar? Anyone?

I also have the HTC BH S600. I experience the same problem, but only for the first 5-10 seconds when initiating or answering a call. My belief so far is that the headset causes the problem due to noise cancelling in the headset. Are you sure this is phone-related?

Therefore yes, I'm pretty sure it's a problem with our Xperia Z1.
If you want to repeat my test, just go to Settings -> Call Settings and at the bottom, add any SIP account (like ekiga, or any free sip provider), then enable Internetcalling (to sip addresses only) and call email@example.com
You will hear your own voice input unfiltered just like another person would hear it.
You might also call yourself on a landline.
I'm very anxious to hear about your results. :-)

Have you contacted Sony Support? Any feedback? Will try to do some tests myself, later. However, so far I have only noted these issues when using the HTC headset. I am using Bluetooth in my car, and noone has complained then. I have tried also MW600, also without complaints (even though the MW600 is useless since it ends up "hanging" several times when trying to use it a full day).

The issue persists on Android 4.4.2 KitKat
have contacted Sony Support, currently waiting for reply.

Issue persists on Firmware 14.3.A.0.757
Just once, before the firmware update and during a sip-echo test I experience the same effect as Uffez described,
where the volume would increase to acceptable levels after about 30 seconds. However, couldn't distinguish if that wa caused by an increase in the recording volume or increase of the playback volume due to Speaker voice enhancement being on.
Tested the headset on a Samsung Galaxy 4 Active (Android 4.3), which displayed the same issue: me bing almost unhearable throughout the whole conversation.
Again tested it on a Nokia E71 and Nexus 5 which had no issue at all and I was clearly audible from the first moment on.

Same Issue here,
I have Samsung Galaxy S4 - tested with official ROM (4.2, 4.3) and than with rooted phone and Google edition 4.4.2 rom, still same.
I have connect Headset to Lumia 520 and make call to my S4 and it is working without any audio problem, as it should.
When Calling from my S4 with headset connected to that Lumia back, problem occur and after few tens of seconds it is no better.
Than I have tried to call to Nokia 2730 and still same problem.
After all this I have pair headset to Samsung Galaxy Nexus and call to my S4 - everything OK ...
So problem is somehow related to some android devices and lies between headset and connected phone.
And now I have found this (probably faulty Automatic Gain Control) which might be same or similar issue ...
Also in this topic is written that new Android 4.4.3 should fix this issue. I will try to update my S4 to 4.4.3 and will see if it helps ...

Same here. Sony Xperia Ultra. Normal mic works perfectly. The one via bluetooth barely records my voice.
I have tried a few headsets, so I'm sure it is not a headset problem.
Automatic gain control, you say? Yes, sounds plausible.
My phone though is on 4.4.4, so the fix in 4.4.3 did not help.
