As in the pic, they are a little dorky, but sound is great. I am not an audiophile, but the sounds seem good enough to me. The reason I gave it three stars is that they advertise that the headband comfort level can be set. Ever since I took it out of the box, I have never able to change it. The switch on the left side does not move at all, and after putting lot of force on the right, it does slide but prefers to slide back down, so sometimes I feel the headphones are squeezing on my ears.
