Well been cycling to work for a while now and the thought has occured to me, whether there are any deivces that could be attched to my handlebars to drown out the traffic noise and give me something to listen to, other than me attempting to sing/hum/whistle any currnet tune (badly). Thought with the Mp3 pen drives and players, with a small pair of speakers would do the job, anyone come across anything like this?
