Engineering a highly realistic sound environment. 

It’s one thing to hear music with headphones. It’s quite another thing to hear music with a realistic sense of width, distance and depth.

That’s exactly what we’ve engineered the AKG® K551 headphones to deliver. Optimized for a fully immersive listening experience, these reference-class headphones use Real Image Engineering to create a highly realistic sound environment with a true sense of dimensional space. Two 1-31/32-inch (50-millimeter) drivers, the largest in the AKG product line, produce powerful, detailed sound from portable devices and home audio systems alike. The K551s’ closed-back design offers enhanced passive noise reduction and extremely low sound-leakage levels, while an in-line microphone lets you answer a call from your iPhone as easily as you listen to a song. With large ear cups and a lightweight headband, the stylish and portable K551s provide hours of comfortable, continuous listening and let you take AKG studio-quality sound with you wherever you go. And when you’re not using the headphones, a 2D-axis fold-flat mechanism makes them easy to store or transport. The headphones’ classic, sophisticated design proves that this impressive headset isn’t engineered only for the ears. Your private, immersive sound environment awaits.
