Sound quality and comfort are really good. No Question. The best I've ever had on the ears. However, the quality of the processed plastic is appalling! After just over a year of my headphones are broken today. I would definitely not expect from Yamaha. Not in a product in this price range. After about 3 months the supplied cable had a broken cable. Should not happen. Have it replaced by one of the monitor, which is until today without any problems in use. Now I look for new headphones and it will definitely not draufstehen Yamaha again!
