The S9 has worked great as a headset to use while working out in the gym.I have also used it to listen to music with while riding my motorcycle via a bluetooth link to my cell phone. I was even able to receive a call with it (auto answer turned ON when headset connected) but not while riding. I had to stop because of wind noise. I would not recommend this to be used as a permanent solution for communications while riding, but it does help in a pinch. Also, if using it just for music while riding, there is no volume control. It's truthfully not the safest option for in-helmet music and phone. You should probably just go with one of those headsets that Scala or BlueAnt makes for motorcycle helmets. I'm looking at the BlueAnt Interphone F4.
