Closed-Back Headphones with Amazing, Comfortable Fit

With the K550MKII Closed-Back Reference Headphones, AKG engineers have struck a masterful balance between the noise-isolating qualities of closed-back headphones, and the spacious, dimensional sound of an open-back design creating reference-class headphones ideal for private listening both at home and on the go. 50mm drivers, the largest in AKG's product line, deliver great AKG sound from your hi-fi system or virtually any portable device. The large ear cups and new headband design ensure an amazingly comfortable fit, and the 2D-axis mechanism folds flat to stow and go.
