the long awaited update to 1.3.1 did repair the complete malfunction of the Pre with that headset indeed, but only to deliver unacceptably bad sound quality. It does sound like the Pre cannot deliver a high bit rate like 320kBps or even 256.
Actually the Centro does the job much better using AudioGateway.
Any Sony owners suffering the same?
Is the Pre really unable to stream high bitrates for quality audio over BT?
