I've decided it is time to enter the 21st Century and buy a Bluetooth helmet headset so I can (1) listen to music on my iPod, and (2) make and receive phone calls on my Blackberry - I don't think I would ever use bike-to-bike intercom nor do I need an FM radio. I've done a little research and it seems that there are basically three solutions for my Scorpion EXO-700 helmet, the Cardo Scala Rider Solo and intercom-capable Scala Rider Q2; the SMH10, and the BlueAnt Interphone F4.
It seems price runs about $150 to $250 for these things, but I have found one vendor selling the Scala Q2 for $120 (so that is top of the list for now...)
Anyone have these or others and want to comment? Comparisons would be especially helpful!
