AKG K701 Open-back Studio Reference Headphones

Description

The AKG K701 takes over! For 15 years, AKG’s K1000 headphones ruled the audiophile’s world. Now, they pass the mantle of super-accurate acoustic reproduction to the new K701 – the first headphone to employ cutting-edge flat-wire voice coil technology along with AKG’s patented Varimotion technology. The result is a truly dramatic sound that places every musician at their correct location with pinpoint accuracy. This kind of agility and spaciousness coupled with brilliant highs, and velvety, punchy bass is simply miraculous. The superlative K701 open-back dynamic headphones provide an outstandingly accurate sound and excellent imaging. Find out what ingenious headphone engineering can do for your listening experience – try the AKG K701s!

• Bi-wiring, high-performance cable
• Individually tested and numbered

Revolutionary flat-wire voice coil technology

Whether you prefer the holistic approach or like to listen analytically, the K701s will turn perception into pure enjoyment. AKG is the first manufacturer in the world to use revolutionary flat-wire technology in headphones. An aluminum flat-wire voice coil moves within a powerful field generated by a computer-optimized axial system of neodymium magnets. This flat-wire coil is smaller and has lower impedance than the K1000’s voice coil, yet its optimal fill factor helps make the motor more efficient, enabling the K701 to work with typical headphone amplifiers (the K1000 requires additional amplification). The combination of a strong and uniform magnetic field with a light yet powerful coil enables the K701’s diaphragm to track audio signals with unprecedented accuracy. The sonic improvement is particularly apparent in the low frequencies.

Patented AKG Varimotion ultra-precision two-layer diaphragm

The K701s have an all-new diaphragm that continues the evolution of the K1000’s multi-layer design. Advanced production technology combines two different materials: the first optimizes diaphragm motion, while the second dampens undesirable breakup modes. AKG’s patented Varimotion technology varies the diaphragm’s thickness: the 80-micrometer center zone is virtually pistonic for well-balanced, undistorted high frequency response, while the highly-elastic 40-micrometer perimeter handles the increased excursion required for accurate midrange and solid bass reproduction.

Self-adjusting leather headband with 3D-Form earpads

Designed in collaboration with award-winning Austrian firm Kiska, the new K701s update AKG’s distinctive design vocabulary with natural materials, including a self-adjusting padded glove leather headband. These new headphones embody functionally aesthetic styling with a bold design in white, brushed aluminum, and sienna. The 3D-Form earpads are specially shaped for an ergonomically perfect fit, precise and repeatable location on the ears, and superior acoustical transmission.

Bi-wiring, high performance cable

AKG engineers considered the entire signal path from amplifier to eardrum when designing the K701. Bi-wired oxygen-free copper cables optimize channel separation. Frequency response is flat from 10Hz-39.8kHz – well beyond the range of human hearing. Sensitivity is 105dB, while power handling is 200mW. But conventional measurements don’t tell the full story of this very unconventional set of headphones. With wide dynamic range and extremely low distortion, the K701s deliver brilliantly detailed highs and velvety yet punchy bass – a perfectly balanced, natural sound that places every musician at a specific location in the mix with pinpoint accuracy.

Individually tested and numbered

The K701s’ deluxe packaging reflects their elite flagship status. Each individually tested, calibrated, and numbered set of headphones comes with its own metal storage cradle, which is enclosed in a presentation case. Like the K1000 it replaces, the K701 is backed by a two-year parts and labor warranty.
