Over the years I have broken a lot of headphones. This one by far is the best built set I have ever owned. I play 2 to 3 times a week. Thursday and Friday at Ninfa's and on Saturday at the club. Not only are these sturdy but they sound like no other headset. The 107 db sensitivity is outstanding. As for comfort. My nine year daughter thinks there very comfortable. Out of all my head- phones. There the most comfortable. I'm not sure what the other reviews are talking about. There worth every penny.
