I rip to monoaural; originally, because I got an mp3 player to help with the morale problem on Audaxes, although the in-ears I used to ride with aren't too bad even with both in. This means in the office I can use a handsfree headset that covers only one ear, the sort intended for telephone use; it looks funny with the microphone sticking up not doing anything, but it suits me. Disclaimer: I have a cloth ear.
