I purchased these headphones at Radio Shack for use in my ham radio station to listen to other hams and shortwave broadcasts from all over the world as well various am and fm stations. I have been very pleased with these as they have delivered very nice audio response to whatever I choose to listen to. The overall quality of them is really pretty nice for the price I paid. Every so often Radio Shack will have a sale on various models of headphones and that usually represents an opportunity to pick up a good pair of headphones at a very reasonable price. I have used them on various radio's here in my radio room and they have sounded great irregardless of whatever radio I want to use them with. They have foam around each ear piece for comfort as well as being adjustable for various sizes. They are actually so comfortable it almost feels like you have nothing on your head at all. A very nice product by Radio Shack.
