Cons: ABSOLUTELY NOTHING!
everything about these headphones is flawless. Everything is balanced, and perfect. Any of the reviews that didn't like them most likely have a fake pair, or, hate life. The only thing I could say for these is that there isn't a TON of bass, but the bass is very good. You have to turn them up really loud to hear really good bass, and the bass is amazing when you turn the volume up. And one of the best things, for me at least, these do NOT leak. At full blast in a quiet store you could barely hear anything when they were on my head (My friend was with me) and it cancels out noise like none other. I have never tried a better headphone. I compared these to the beats pros, that cost $399.99 and the $150 ATH-M50 are about 3x better at least in any and every aspect of the headphones. Try them on at your local guitar center. You will not regret it.
