The AKG K550s strike a balance between the noise-isolating qualities of closedback 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 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 or go.
