5 and they are exact fit as you can see. Not sure if the mouse or apple is to blame on this one, but YMMV. On the right hand side the lights are barely even visible they are so dim. Volume controls worked fine when tested out of the package, mute/pause also works. She loves them ! They pair great with my iPhone & the sound quality & noise cancellation is just perfect! Theyre not too high so theyre comfortable but theyre not so low as to not be fashionable. Buy yourself a pair with the long pants as loungers. So I had posted a review but after having these for some more time, I need to update it. They are very stylish as well, and I plan on getting a fancier pair for the summer evenings.
