To pipe system sounds, video soundtrack and audio the device needs either the A2DP or audio gateway profile. A2DP is for high quality audio, so that's a better one to have and yes, the BlackJack has that profile. The other part of the equation is a headset (usually stereo) with the A2DP profile. Most stereo headsets have the A2DP profile while most standard headsets used for phone calls have only the hands free and headset profiles used to pipe only phone call audio. The BT350 is only for calls. If you take a look at our Bluetooth headset review page, you'll see some of the stereo headsets with A2DP out there.
