What is the lowest bitrate quality you will allow for your MP3's? I try to never go below 192, because anything below that sounds like its in a tunnel or something, especially the cymbals and highs. I don't know, I guess I'm just fussy about sound quality like that. I'm weird. lol I play mine on a 5th gen Ipod Nano 16gb by the way. I mostly listen at work(on the assembly line) and in my car.
