Sony MDR-Z7 Hi-Res Stereo Headphones

Sony MDR-Z7 Headphones

Sony just released their flagship hi-res stereo headphones for $700, model MDR-Z7, which claim to reproduce subtle high frequency sounds up to 100kHz — a first for headphone technology. The MDR-Z7 audiophile headphones meld ultra-responsive audio performance to bring you closer to a live performance. The relatively large 70 mm HD drivers deliver a sound wave similar to that of a loudspeaker, ultimately distributing a highly natural sound from super-low bass response to ultra-sonic frequencies, and providing the listener with an immense feeling of space to ‘feel the air’ as if they were listening to music in a live venue. Lightweight and responsive Aluminum-coated Liquid Crystal Polymer diaphragms also provide uniform sound production across all frequencies without coloration.

Additionally, the Z7 features a 4-wire structure that uses separated ground cables to minimize crosstalk between left/right channels and supports balanced audio connectors while silver-coated OFC cable strands reduce signal transmission loss. The MDR-Z7 also includes a balanced output cable (2m) for improved signal separation with the option of plugging into a compatible, audio amplifier, such as the new Sony PHA-3.

Made in Japan, the MDR-Z7 exudes quality and precision workmanship. The pressure-relieving, ergonomic urethane ear pads were designed using the latest 3D sewing in order to keep the square shape of the internal cushion from crushing or hardening. There’s also an Inward Axis structure that utilizes a slanted swivel axis design to bring the pads closer to your ears, for improved stability, better bass response and long-term comfort.
