Bluetooth handsfree better quality

Is some how posibble to get better audio quality sound when bluetooth headphones are on hands-free mode? Because when is only audio, sound qaulity is good (16bit 44kHz), but when i need talk through microphone, audio quality is changed to poor (16bit 8kHz), like old radio. Or i do not hear something through headpones. 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?
