I just got my new (used) bike, and I'm also a big music nerd and love to listen to music when I'm traveling. Do you personally listen to music while you're cycling, and in your opinion is it safe?
I do mtb trails. It's hit and miss. Sometimes I don't listen to music. Sometimes I'll have one earbud in with the volume fairly low. I never use two earbuds. I've never had an issue, but my biggest concern is being able to hear animals and stuff.
