Nokia n73 (RM-133), FW v4.0839.42.0.1
Jabra BT620s, FW v1-31-0 (latest)
Problem:
Jabra BT620s - is stereo bluetooth headphones.
When playing music there is periodically tone deviation - i.e. speed of playing can be faster then normal, or can be slower. Very unpleasant...
With other phones the qulity is good.
Why it happens?
