AKG K-701 HEADPHONES
AKG engineers have long pursued the goal of bringing the world’s best concert halls into the audio enthusiast’s home. The K-701 represents the closest approach yet to this ideal. This new open-back dynamic headphone uses a newly-developed transducer with a two-layer diaphragm for unsurpassed transient response and accuracy.
AKG’s patented Varimotion design varies the diaphragm’s thickness: the 80 µm center zone is virtually pistonic for well-balanced HF response, while the 40 µm perimeter is highly elastic to accommodate the increased excursion required for accurate midrange and LF reproduction. The K-701 drives this new Varimotion transducer with a flat wire voice coil – another in AKG’s long series of firsts. With an updated design in white, brushed aluminum and sienna, these new headphones embody functionally esthetic styling as well as transparency and accuracy that will excite both audiophiles and recording engineers.
The ultimate reference K-701 is in a class by itself among open-back dynamic headphones, comparable to AKG’s legendary K 1000. Its agility and spacious sound place every musician at a specific location with pinpoint accuracy. Brilliant highs and velvety, punchy bass are the result of several new technologies:
- A revolutionary flat wire voice coil optimizes the “coil fill factor,” improving efficiency and enhancing HF accuracy
- A two-layer diaphragm with AKG’s patented Varimotion design virtually eliminates distortion and delivers exceptional imaging
- A high-performance neodymium magnet structure complements the flat wire voice coil for frequency response of 10 Hz to 39.8 kHz
- A bi-wired oxygen-free (99.99% OFC) copper cable optimizes channel separation and reproduction quality
- A proprietary design, the padded genuine glove leather headband is self-adjusting for ultimate listening comfort
- 3D-Form ear pads are specially shaped for an ergonomically perfect fit
Whether you prefer the holistic approach or like to listen analytically, the K-701 will turn perception into pure enjoyment.
AKG is the first manufacturer in the world to use revolutionary flat-wire technology in headphones, namely, the K-701. The result is a truly dramatic sound that places every musician at their correct location with pinpoint accuracy. This kind of agility, spaciousness, brilliant highs, and velvety, punchy bass is simply miraculous.
These superlative open-back dynamic headphones provide an outstandingly accurate sound and excellent imaging. Try the K-701 and find out what ingenious headphone engineering can do for you.
The AKG Varimotion speaker 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.
Each individually tested and numbered K-701 comes in its own storage cradle, which in turn is enclosed in a presentation case.
