Product Information

MDR-Z7 headphones meld a solid, thoughtfully designed aluminum structure with lush, ergonomic, enfolding comfort, and ultra-responsive audio performance for a sound experience bar-none.

MDR-Z7 Feature:

Hi-Res Audio
Aluminum coated Liquid Crystal Polymer driver units render incredible and linear wideband frequency response including up to 100 kHz highs and augmented lows (4-100 Hz) for an audio experience without equal.

Wide, natural sound field
Almost like listening without headphones. Unlike the smaller drivers found in other headphones, that create tight, spherical waveforms, the 70 mm ALCP Film driver units of the MDR-Z7 deliver detailed, natural, and pleasing planar sound waves with all the atmosphere of the original recording.

Aluminum Liquid Crystal Polymer HD Diaphragm
Lightweight and responsive Aluminum Liquid Crystal Polymer Film HD diaphragms provide the necessary rigidity, light-weight, and internal loss for wide, balanced and highly accurate sound reproduction (4-100 kHz)…

4-conductor oxygen-free cable (supplied)
Oxygen-free audio cable ensures minimal signal transmission degradation for pure audio response at the driver. 4-wire architecture further enhances the audio experience, with a separate ground and signal connection to each driver for enhanced separation, expanded sound, and tight bass.

Balanced Audio capable
As with a stereo featuring dedicated left and right channel audio output, for the ultimate headphone experience you need to plug-into a compatible, balanced audio amplifier (PHA-3 for example) for pure, unadulterated sound…

Extended Comfort
Pressure-relieving urethane cushions wrap entirely around your ears for a comfortable acoustic seal and powerful bass response while 3D sewing of the covers avoids crushing and hardening of the padding.

Upgrade your cans!
Elevate an exceptional listening experience to new heights using cables engineered with Kimber Kable®. Aesthetically-pleasing braided wire paired with precision hardware facilitates the noise-free delivery of your favorite good vibrations to your ears. Three models are available to suit: on-the-go (MUC-B12SM1), at-home (MUC-B30UM1), or balanced audio listening styles (MUC-B20BL1). Consult your dealer for further information.

Silver coated OFC cable
With less inherent electrical resistance than standard copper cabling, silver coated OFC (oxygen free copper) cable minimizes signal transmission loss to ensure that only rich, sweet sounds reach your ears.

Beat Response Control
Acoustic ports within each ear cup housing help control airflow for optimized diaphragm movement for accurate sub-bass response.

Enfolding design
Delivers wrap around comfort with an improved acoustic seal for deep bass response.

Inward Axis Structure
Placing the hanger structure axis inside that of the diaphragm housing provides optimum, stable fit.

Silent Joints
Precise machining, in addition to the placement of silicon rings around every moving axis, realizes smooth and silent earcup movement for an immersive music experience devoid of annoying mechanical rattling.

Two cables supplied
Two, supplied cables accommodate high-fidelity, listening flexibility. A conventional connecting audio cable (3 m), in addition to a balanced output cable (2 m). A Gold-plated unimatch plug adaptor (Stereo Mini Cable -> Stereo Phone Plug) is also included.

Made in Japan
Hand made in Japan, the MDR-Z7 exudes quality and precision: in your hands and on your ears. Put a pair on and listen for yourself.
