I can't use a Walkman at work on my patrol rounds because I'm supposed to be able to hear what's around me as well as hear my patrol radio. I recently came across an MP3 player, and I'd love to use it on my rounds, but I have to overcome a few limitations. I fugure, if I could find a GOOD monural headset, I could hear what goes on around me with my other ear, but that might not be good enough. If I can get a headphone that accepts two sources, and can cut off one when the other is being used, that would be perfect (The radio has a jack for a headset, though I'd just be using the headphones part...). Anything like either of these exist anywhere? Thnx ppl :D
