Terrible w/ My BT Headset Sony E. MW600
Well, I bought a MW600 BT headset last year for my Vivaz (SE).
(No quality I have wanted because of A2DP is not well developed for music)
After a half of year, I get my Galaxy Tab P1000 (at that moment it was official 2.2.1 )and tried to play music w/ it. But in result, a really really bad quality I have been gotten.
Well, then, I left it alone for a long while until the official 2.3.3 was released but however the result was still bad.
Unfortunately, the result in every custom rom / kernel is still getting wrong w/ it.
So far, I put it under my bed and leave alone forever.
