K-340
The K-340
headphone surpasses even the most elaborate electrostatics in transparency and
accuracy. It has deeper and more precisely defined bass than is available from
the most expensive loudspeakers, while
also being completely free from the effects of room acoustics. Every detail of
the sound is clear and natural, and the acoustic image is better localized than
with any other headphone available. Listening fatigue is the biggest enemy of
headphones - but you can listen to thecoloration-free K-340's hour after
enjoyable hour.
A
headphone's acoustical performance is academic if it is uncomfortable to wear,
so every unnecessary ounce of weight was eliminated. The K-340 - despite its
dual transducers and crossover networks - weighs about the same as an average
open air headphone. Side pressure against the head is very low, and the large
ultra-soft urethanefilled circumaural earpads may be removed for cleaning. The
headphones are supported by a wide, soft headband with raised pads which not
only permit air to circulate, but also provide flexibility to conform to the
exact curvature of any head. Strength is supplied by a dual-bow bail above the
headband. The bail terminates in a pair of self-adjusting slide fittings that
automatically position the earpieces at the proper height.
The
K-340 comes with a 3 meter coiled input cable that terminates in a standard ¼" stereo phone plug. The cable's flat,
side-by-side conductors are specially designed to reduce kinking. The input
cable is brought directly to the left earpiece, and the headphone bail carries
audio to the other earpiece, doing away with distracting "Y" cords
under the chin. No detail has been overlooked in the design and every detail is
revealed in the music for your enjoyment.
