Gayer than a Google Glass..
Wait, what? How old are you? This is a bodybuilding board, right? When it comes to training attire, that mp3 player nor the Google Glass are anywhere near as gay as parachute pants, flannel shirts with no sleeves, or pretty much anything Flex Wheeler wore for training in the late 80's/early 90's.
I'm not ashamed to admit that while training I used to listen to a Sony Walkman CASSETTE player while carrying it around in a fluorescent green fanny pack. Compared to that, NO plain black mp3 player is gay in the slightest.
