See included photos. It fit perfectly from the moment I tried it. Sketchers have not failed so far. I have read some negative reviews about the bass quality on this product. Muy buenos y muy comodos I also needed something rechargeable and wireless. Sound Quality:These headphones have a pretty accurate sound and do a good job in the mids and highs. It also helps with posture. Theres plenty of room to store a mouse, external hard drive, etc. Very satisfied.
