Key Features

Famous AKG sound quality

For over 65 years, AKG Acoustics has been the leader in creating studio sound in headphones. We hold over 1,400 patents for our groundbreaking products, plus two technical GRAMMY Awards (in 2010 and 2005) for sound innovation.

1-31/32″ (50mm) drivers

Powerful 1-31/32-inch (50-millimeter) drivers enable AKG K551 reference-class headphones to do things that other headphones can only imagine. Music is rich and layered, while sound environments seemingly unfold before you no matter how loud you turn up the volume.

Real Image Engineering

Real Image Engineering is the science that fits an actual soundstage inside the space between your ears and the AKG K551 headphones. With Real Image Engineering, sounds are huge and accurate, with an incredibly realistic sense of width, distance and depth.

Outstanding passive noise reduction

Traffic is loud. Subways are loud. Other people’s phone calls are loud – and annoying. But you may never know it, because AKG K551 headphones offer effective sound insulation. Premium foam ear pads wrapped in soft leather help create an acoustic seal, so all you hear is the music you love.

Closed-back design

The AKG K551 reference-class headset keeps music in and noise out. Its closed-back design helps prevent outside noise from entering your ears and minimizes sound leakage. So your music is yours and yours alone to enjoy anywhere you go.

In-line microphone and remote control

AKG K551 headphones have an in-line microphone so that you can make calls that are every bit as crisp and noise-free as the music you listen to on your iPhone. The mic is ideal for FaceTime and Skype applications, and virtually any app requiring a microphone. The headphones’ three-button remote lets you control the playback functions and volume from iPhone and iPad devices, as well as Apple laptops and desktop computers.

Classic-meets-contemporary design

Great music doesn’t go out of style, and neither will the AKG K551. These reference-class headphones are sleek and sophisticated, with a commanding yet minimalist design that is available in either white or black and silver.

2D-axis fold-flat mechanism

Though you may never want to, you will take your AKG K551 headphones off at some point. When you do, the AKG K551 folds flat for simple, worry-free storing and transporting. High-quality, metal-alloy material keeps the folding mechanism strong and durable.
