Enjoy music as the artist intended with High-Resolution Audio
Take your digital music collection to another level with High-Resolution Audio. By converting analog music to digital at a higher rate than CD (24 bit/192 kHz, rather than 16 bit/44.1 kHz), High-Resolution Audio allows you to get closer to the original studio recording and enjoy your music just as the artist intended.
Massive HD drivers deliver engaging sound
Mighty 70 mm HD driver units power through your music, keeping every note precise, no matter how high you turn up the volume. Because of their massive size, these drivers create a plane wave effect in the earcups that prevents reflection delays and minimizes sound loss. So you can hear all the emotion and energy of the original recording with punchy bass and crystal-clear high notes.
Wide frequency response for a full range of sound
The wideband frequency range—4 Hz to 100 kHz—is designed for today's broad variety of music styles. The 4 Hz low end of the frequency range offers more than enough latitude for even the deepest sub-bass notes. At the 100 kHz high end, you'll be able to enjoy vocal melodies, subtle audio harmonics and tonality, giving your music more life and realism.
High sensitivity for a clear performance
With a high sensitivity of 102 dB/mW, these headphones are highly efficient in converting electricity into acoustic signals. That means you'll hear a clearer sound across the entire audio spectrum (compared to less sensitive headphones) when listening to music through the same source and at the same volume level.
Aluminum-Coated LCP diaphragm for more precision
An aluminum-coated, liquid crystal polymer diaphragm gives a more consistent and precise sound across the entire frequency range than a conventional LCP driver. Sound energy lost during transmission to the headphone housing is more uniform, to ensure a true and authentic performance. You'll also enjoy a flatter frequency response, even when listening to the ultra-high frequencies of High-Resolution Audio.
Enfolding closed-back design seals in sound
The closed-back, enfolding design wraps around the ear, helping to seal in music and keep distractions out. Acoustics are reflected back towards your ears, so you'll hear even the subtlest of sounds. You'll also feel every beat, as the closed-back design helps to maximize the bass signatures in your music.
Balanced audio cuts cross-talk
With a balanced four-wire connection and silver-copper dual cord, audio channel separation is improved for better sound. Unlike conventional headphones which share a ground wire, the cord includes left, right, and independent ground wires for both channels, so you'll hear less distortion and cross-talk.
Made in Japan for superior quality
Made in Japan, Sony products are synonymous with absolute quality and performance. Only the finest components and manufacturing techniques are used to create headphones that push the boundaries of sound purity.
All-metal design keeps sound stable
Constructed in high-density metal, these headphones suppress unwanted vibration and keep sound stable. The metal housing resonates less than housings made from more traditional materials to give clearer mids to highs and smoother low-frequency sounds. A metal hanger sleeve, shaft, and hinge ensure excellent durability. For wearing comfort, the light and flexible metal headband can be easily adjusted to fit perfectly around the head.
Luxurious leather earpads for total comfort
Soft leather earpads, designed to shape around your ears, give a secure and comfortable fit. Smooth materials and seamless sewing provide a harmonious mix of comfort and durability for long hours of listening.
PHA-3 compatible lets you hear High-Resolution Audio
Take your music farther. The optional PHA-3 portable DAC amp takes the digital output of your PC, smartphone, or Walkman® and converts the signal to an analog output for amplification. One of the world's first headphone amplifiers to support 384 kHz/32 bit PCM, DSD (5.6 MHz), and balanced audio output, it's perfect for pairing with these headphones.
