I get a MDR-1RBT MK2        the bass is strong i think  . However , the sound quality using wired mode is better than BT mode , with more bass and detail   http://<embed src="https://app.box.com/embed/gsczd3vrzu7y7mi.swf" width="466" height="400" wmode="opaque"...

Sony XBA series is great even i am using  XBA-BT . However , sound quality is greatly affected by the bluetooth signal transmittion source . (extremely great with notebook , but ordinary with a phone )   I am just wondering whether XBA-1 and XBA-BT75  sound the same ?  as i  am thinking of...
