With the K 550s, 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 our 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 or go. Matte black finish with black metal accents.

Outstanding Sound:  The 50mm (2'') driver, the biggest driver in the AKG headphone range, delivers a realistic soundstage – far beyond what other headphones typically deliver.  

Cozy Fit: With large ear cups and a new, lightweight headband design, the K550 offers an amazing, comfortable fit allowing for hours of continuous listening.  

Great Compatibility:  The K550 works and plays well with virtually any portable device including iPod, iPod touch or iPhone.
