The KDX/300 includes small, medium and large silicone ear cushions for a customized fit to enhance isolation when you want to eliminate ambient sounds that interfere with the listening experience. Built to last, the KDX/300 is covered under the Koss’ No-Questions-Asked Lifetime Warranty - the only warranty of its kind in the stereophone industry.

Owner Reviews, Ratings, Comments and Criticism
These headphones are awesome, lots of bass. I like the kind that seal in your ear, these do that. I like these because they don't get as dirty as the other foam ones Koss sells. Lifetime warranty, which I've executed many times with another set. $6 check for shipping and you get a new or refurbished pair.
