SONY / MDRZ7

Equipped with a newly developed large-diameter 70mm HD driver unit, these flagship high-end headphones reproduce sounds from low to ultra-high frequencies up to 100kHz. Compatible with high-resolution audio sources, they even reproduce the atmosphere of music.

■ Achieves ultra-high frequency reproduction of 100kHz, far beyond the audible range
■ Compatible with high-resolution audio. Large-aperture 70mm driver unit for wide-band reproduction
- Equipped with a newly developed large-aperture 70mm driver unit. The large diameter reproduces wavefronts that are nearly flat. The wide, flat sound wavefront allows you to experience a natural sound, just like listening to music on speakers. Furthermore, wide-range reproduction, from low frequencies far beyond the audible range to 100kHz, faithfully reproduces the airy nuances of music unique to high-resolution audio sources.
■ Aluminum-coated LCP diaphragm
■ A thin aluminum film is coated on LCP (liquid crystal polymer), which has ideal properties as a diaphragm material. The interaction between LCP and aluminum achieves high, flat internal loss characteristics across the entire frequency range, reproducing clear, uncolored mid- and high-range sounds.
■Beat Response Control accurately reproduces deep bass rhythms
・Ports (vents) on the housing control airflow resistance in the low range. Optimizing diaphragm movement improves low-frequency transient characteristics, resulting in accurate rhythm reproduction.
■Ergonomically Stitched Ear Pads
・Ergonomic 3D stitching ensures the ear pads gently fit the contours of your head. Maximizing the softness of the urethane foam improves fit.
■Enfolding Structure for a Comfortable, Enveloping Fit
・Ear pads made of low-resilience urethane foam sewn into a 3D shape and designed to collapse inward, they envelop your ears, providing a comfortable fit and a high level of airtightness. This reduces sound leakage and reproduces the full power of deep bass frequencies.
■Silent Joints reduce rattling of moving parts
・Reducing mechanical noise when worn allows you to immerse yourself in music listening in silence.
■Inward Axis Structure
・Features a unique hanger structure. The housing's rotation axis is facing inward to improve wearing stability.
■Design that combines high rigidity with a luxurious feel
- Metal is used for the hanger, and genuine leather is used for the top surface of the headband. Attention to detail has been paid, and the diaphragm protector has also been newly designed. The design emphasizes durability while also having a luxurious feel.
■Independent ground cable
- Separate grounding and a four-core configuration reduce crosstalk. Enjoy a wide soundscape and tight bass.
■Detachable cable also supports balanced connections
- In addition to the regular headphone cable, a balanced connection headphone cable is included. By connecting to the separately sold portable headphone amplifier (PHA-3) that supports balanced output, you can play music with higher sound quality using balanced output.

スタッフレビュー

オールブラックのアルミ製ハウジングが高級な雰囲気を醸し出しているSONY/MDR-Z7。

ドライバーユニットには、なんと70㎜径という今までのヘッドホンには無い、超大口径のドライバーユニットを採用しています。その音はもはやヘッドホンというよりもラージスピーカーで音楽を聴いているよう。
レンジは広く、360度から音が飛び込んでくるようで、立体的で臨場感ある音場がなんとも印象的です。音の解像度も申し分なく、音の繊細な響きや残響を自然に再現していて、ついつい聴き入ってしまいました。

また、肉厚で耳をすっぽりと覆う大口径のイヤーパッドは、高級マットレスを彷彿させる、もっちりとした弾力、しっとりとした肌触りがなんとも快適。実際に装着してみると、側頭部に吸い付くようにフィットして、かなり快適な装着感はじっくりと音楽を聴き込みたい方には最適です。

MDR-Z7は、決して手に入れやすい価格帯のヘッドホンではありませんが、実際に聴けば納得、価格だけのことはあるSONY屈指の高級ヘッドホンです。ぜひ、一度は試聴することをお勧めします。
