Product Details

Sony Black Around-The-Ear Hi-Res Stereo Headphones - MDR-Z7

Listen to your favorite tunes with these Sony Hi-Res around-the-ear headphones. They provide high-resolution sound that's ideal for audiophiles who want balance and impressively responsive performance from the very first note. An aluminum structure supports these music headphones so that they withstand everyday use, yet they fold up within moments so that you can pack them away when they're not needed. High-conductivity silver-coated copper cable reduces signal transmission degradation substantially so that the transmission is maintained from the output to the driver.

Portability aside, the aluminum-coated liquid-crystal polymer driver units are extremely rigid so that they reproduce sound with exceptional precision. They also deliver linear wideband frequency responses from 4Hz to ultrasonic highs of up to 100kHz so that you can enjoy the full range of sound. Tight spherical waveforms are produced from these Sony headphones to create a more natural sound, producing an impressive atmosphere from all your audio recordings. A comfortable fit is assured from these Sony Hi-Res around-the-ear headphones, letting you wear them all day long, relieving pressure and ensuring minimal sound intrusion.


  • Enjoy 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
