On my BMW K100RS4V (low fairing- wind hits me on the shoulders and up)
Velcro'ed in speakers in my Schuberth S-2. A sort-of quiet helmet.
Foam ear plugs
Music from a Zumo 550- MP3 or XM radio
Cell phone (just to hear voice mail, NOT to talk on while riding), radar detector and the Zumo music all running through a Mix-It 2 in my tankbag.
