I just got these for my birthday yesterday and they are SICK. I was just listening to Metallica in them, and it sounded like there was a fucking SUBWOOFER in my head. These things have great crystal-clear sound, and they're really comfortable. Remarkable quality for being an earbud design. Also, probably the most important part, remarkable bass output for such small speakers. Overall, killer headphones. Anyone else ever own a pair of these?
