Default Stereo Sound via Bluetooth

Good day!

I own YP-P2 (4.05b firmware) and SonyErricson HBH-DS220 stereo bluetooth garniture.

Both supports Bluetooth 2.0

When listening music, i'm hearing nice at all sound, but with noise at high frequincy.. like they are ripped. When using the same phones w/o bluetooth - everything is fine.

At one hand we have: non-compressed sound needs 1378 KBit/sec (44100 * 2 (16bit) * 2 (Stereo) / 1024 (KBytes) * 8 (KBits))
but Bluetooth 2.0 allows only ~710 KBit/sec.

But in other hand, Bluetooth 2.0 has EDR with allows 2.1 MBits bandwith, and A2DP supports SBC codec.

So, where's the problem? in P2 or in SE garniture or in Bluetooth technology?

Thanks :>
