arctic p311 bluetooth headset crappy sound

i connected my new arctic p311 bluetooth headset to my laptop. I can hear and speak as expected.

But the sound quality of what i can hear is really bad. When i change audio hardware setup in phonon to high fidelity the sound is great but i can not use the microphone.

Does that mean whenever i wan to use the microphone i must live with the bad sound quality of the headphones?

Or can i use the mic and the headphones with high sound quality? How can i do this?
