I like how this headset looks and it does the job.Be sure to charge the headset before use!!MacBook1. Simple pairing, I was not even asked for a passcode.2. Using the stereo over mono option at first gave me static with my music, but after I did a disconnect/reconnect, it worked fine.3. Volume and track controls work well with iTunes.4. I used the mic with GarageBand and it worked fine.5. I tried using both audio and voice with Yahoo! Messenger but it won't work at the same time (eh).iPhone1. I needed to put the passcode in when I paired the devices, but pairing's also relatively painless.2. Works well with the iPod app, but the volume and track controls do not work (eh).3. I tried Pandora and it works fine with it too.4. If you have ringtones, you won't hear the music through the headset, just a regular ring.5. Voice is only heard from the left side.I am yet to buy a Bluetooth transmitter for my iPod Nano 5th gen and I will post an update then!!
