iPods Nano

probably comfortable, because they are very small, you can put them anywhere or even not put them in, they should hang on the headphones themselves, and hold on)

Distorted Impalement - 2009 "Straight In Your Face"
I don't like all sorts of grindcore and the like, but this album is simply a masterpiece. I recommend it to everyone who can listen to very heavy and brutal music.
