My wife hears something bad and in television so we always had minor problems with the volume. We opted for the HDR 180 headphones, because we had already had good experience with Sennheiser. The headphones are great class, just great in use, the sound anyway absolute peak. We have been able to convince a number of our friends on the quality of these headphones and hear true enthusiasm. Our headphones are approximately 1 year in use, the enthusiasm continues and we still have needs no new batteries.
