Audiophile Headphones with Cutting-edge Flat-wire Voice Coil
The AKG K 701 takes over! For 15 years, AKG's K 1000 headphones ruled the
audiophile's world. Now,they pass the mantle of super-accurate acoustic
reproduction to the new K 701 - 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, spaciousness, brilliant
highs, and velvety, punchy bass is simply miraculous. The superlative K 701
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 K 701!
AKG K 701 at a Glance:
- Revolutionary flat-wire voice coil technology.
- Patented AKG Varimotion ultra-precision two-layer diaphragm.
- Self-adjusting cushioned genuine-leather headband and specially shaped
"3D-Form" ear pads.
- Bi-wiring, high-performance cable with 1/4" jack plug.
- Individually tested and numbered.
Flat-wire Voice Coil
Whether you prefer the holistic approach or
like to listen analytically, theK 701 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 - another in AKG's
long series of "firsts" - 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 K 1000's voice coil, yet its optimal
fill factor helps make the motor more efficient, enabling the K 701 to work with
typical headphone amplifiers (the K 1000 requires additional amplification). The
combination of a strong and uniform magnetic field with a light yet powerful
coil enables the K 701's diaphragm to track audio signals with unprecedented
accuracy. The sonic improvement is particularly apparent in the low
frequencies.
Varimotion Ultra-precision Two-layer Diaphragm
The K 701 has an
all-new diaphragm that continues the evolution of the K 1000'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 HF response, while the highly-elastic 40 micrometer perimeter
handles the increased excursion required for accurate midrange and solid bass
reproduction.
Self-adjusting Headband
Designed in collaboration with
award-winning Austrian firm Kiska, the new K 701 updates AKG's distinctive
design vocabulary with natural materials, including a self-adjusting padded
genuine 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
AKG engineers considered the entire signal path from
amplifier to eardrum in designing the K 701. Bi-wired oxygen-free (99.99% OFC)
copper cables optimize channel separation. Frequency response is flat from 10 Hz
to 39.8 kHz, well beyond the range of human hearing. Sensitivity is 105 dB while
power handling is 200 mW. 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 K 701 delivers 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 K 701's deluxe packaging
reflects its 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 K 1000 it replaces, the K 701 is
hand-crafted in Vienna, Austria by AKG's most experienced builders, and is
backed by a two-year parts and labor warranty.
