How about sony DR BT 21 G, and what happens when connection lost?
I am using sony dr bt 21g for about a year now. I like the fact that the band holding the headphones together is behind the head and not on top - having it on top instantly makes it non-sport-compatible - because it's not fixed on the head.
There is only one thing that really bothers me - if you're walking below or in an area with a lot of electric cables (i.e. in the city) the connection to the mobile will break now and then. Afterwards, when the connection is there again, the music is accelerated for a couple of seconds, pretty annoyingly.
Did you test jaybird and jabra for this situation?
