AKG Acoustics K550 Reference Heaphones

*This product is offered exclusively to private users and not to commercial or semi-commercial retailers.

Want great, outstanding Sound and listening comfort from your Mobile device? AKG K550 is an exemplary corded Headphone with studio reference Audio quality that folds for convenient mobility. AKG K550 is the refinement for an audiophile approach to appreciate Digital music.

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. 


  • 114dB SPL for great volume efficiency
  • 2D-Axis fold-flat mechanism for easy storage and transportation
  • 3.5 to 6.3MM adapter (screw-on)
  • Cable - 99.99% oxygen-free cable, 3m
  • 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.
  • Frequency range - 12Hz to 28kHz
  • Input impedance - 32 ohms
  • Main connection - Hard gold-plated 3.5/6.3mm jacks
  • Maximum input power - 200mW
  • Net weight (without cable) - 305g
  • Outstanding passive noise reduction
  • 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.
  • Real Image Engineering for accurate definition and impression of width, distance and depth
  • The Best of Both Worlds - Combines the advantages of closed-back headphones (no sound leakage for a truly private experience) with the open sound of open-backs (typical speakers sound) - making it ideal for both home and street use.
  • The K550 works and plays well with virtually any portable device including iPod, iPod touch or iPhone.
  • Very low sound leakage levels
