Is it somehow possible to get better audio quality sound when Bluetooth headphones are on hands-free mode? When it is audio only, sound quality is good (16-bit 44 kHz) but when I talk through the microphone, audio quality is changed to poor (16-bit 8 kHz) like an old radio. Or I do not hear something through headphones. I have Creative Sound Blaster Jam.
Simple, have set Bluetooth Audio Renderer (Bluetooth stereo audio), for playing, with Bluetooth Audio Input Device (Bluetooth Hands-free audio), for recording?

Short:
No
Long:
There are so called Profiles in Bluetooth, and only one can be active at a time.
A2DP supports one-way HQ audio (unless hacks)
HSP/HFP support two-way audio, but only with very poor quality (HFP 1.6 added mSBC, which is a 16kHz mono codec, before, it was even worse).

(I added the same answer to both Is it possible to use a bluetooth headset mic while having High quality sound and Bluetooth handsfree better quality because they are found using google.)
