I ride with an Ipod Nano hooked up to a pair of noise-cancelling earbuds. Even the quietest helmet (Shoei Qwest) requires earplugs on rides over a few minutes, and I like listening to music, so I've combined the best of both requirements. The 'buds are plugged into a Belkin Rockstar splitter along with a lead to the radar detector, so I get early alerts when the po-po are trolling for revenue. The bass range is not what it would be with a full-blown stereo system, but it's not too bad. The noise-cancellers blank out steady-state noise and let intermittent sounds come through, so wind and motor noise is reduced without impairing safety. For those who say listening to music while riding is unsafe, please turn off your car radios.
