I work out in the middle of nowhere and the radio signals suck. I pay for XM radio and either plug directly into the radio with ear buds or use the FM transmitter and wear AM/FM hearing protectors. I spent years listening to nothing but the engine hum and it drove me nuts. With a radio, I at least feel like I'm not missing anything.
