AKG K171MKII Closed-Back Studio Headphones

The newly designed K171MKII combines the benefits of a closed-back design with the lightweight and comfort of supra-aural headphones.

The K171MKII is an excellent choice for DJ and broadcast applications where no sound can bleed from the headphones into live microphones.

The closed-back, loud and rugged design gives the K171MKII a different low-frequency character and maintains its comfort and flexibility.

Varimotion: The basis of superior audio performance
The heart of any headphone is the diaphragm. Made of extremely thin foil, the diaphragm is required by transducer designers to perform incredible, almost artistic feats. The rim of the diaphragm must vibrate elastically while the center portion should move like a piston. AKG achieved just that by designing the Varimotion system.

The "sound zone" in the center is thicker than the rim and therefore moves like a piston with no partial oscillations. The result is an absolutely realistic sound, with a better sonic perspective and an airier high end. The rim, or "movement zone", is thinner and vibrates more easily, providing a powerful, punchy bass range.
