These fit as expected and have held up very well for my wild toddler playing in them. The tight ear seal gives you unusually good bass, with maybe a touch extra boom, and yeah, a lot of AKG models lack bass, but the bad is that to me, the mid to treble is noticeably low by comparison to my other two pairs. Im on my 3rd pair and will continue to buy these if available. You know how the little stopper on the wall jiggles after a door hits it? That?s these babies. Super quality nice product but size to large delivery to late I listened to some music the first night and thought I would write "exactly what you would think $13 ear phones would be". I didnt try out all of the functions, but I noticed that they can increase/decease volume with a single tap on the right/left earbud, and that wasnt mentioned in the manual. It wears off after about a month, but it was hilarious because every time I would open it in the elevator on the way out of work, it would flood the elevator with this strange sickly sweet chemical smell. I had checked all the reviews first and there were lots about this very thing so I felt confident in doing so. I?m size nine.
