These headphones are great! They are authentic and come in the original packaging. I use them mostly to study (I listen to static noise) and I wear them during my runs. They fit a little snug, but that may be because I have a large head. They feel most comfortable without my glasses and earrings.
When I listen to music the sound quality is amazing. I put them on when I am cooking and it really puts me in the groove. My chef skills have definitely been enhanced following the purchase of these headphones. If you can't cook, buy Beats for some good eats!
