strange. isnt that why there's a handshake between the headset and the phone, even with the same model of phone?

But we kept hearing the person he's talking to also like he has his phone turned up real loud. Turns out some reason my friend's bluetooth headset kept picking up the other guy's phone convo and turning off the speaker/mic on his phone. We showed him and they both had the same Motorola headset. The other guys headset didnt pick up any of my friend's calls though. Weird.
