Before posting, I wanted to test it. It is perfect. It restores a square its not colorized, and cash decibels. I use it only for TV, so in regard to the hi-fi, it is better a more suitable model. I know of Sennheiser and its good reputation for many, many years, I am not disappointed. As against the arch is a little too stiff for my taste, this is why I take off a star. Not good for big heads. It is tough, not like some that I had bought, which fell into disrepair (not name the brand) ..
