Better Tech = Sony's Hi-Res Headphones 

The MDR-Z7's became the first to reproduce high frequency sounds up to 100 kHz - only Sony's premiere headphones can provide this level of audio performance. You will hear every sound on a wide spectrum with the Sony Ultimate Hi-Res Headphones, and their patented 70 mm drivers are capable of delivering bellowing lows to vibrant highs. The goal: provide the listener with original sound, the way the artist intended. Absent getting your favorite performer over for a backyard concert, listening to these headphones might be the closest you can get to the incredible feeling of a live performance. 

Bigger Drivers, Bigger Sound

Some headphones, good ones, in fact, have 1.57-inch drivers to pump the sound. This model has 2.76-inch drivers, which transmits sounds in straight waves as opposed to spherical ones that come in the smaller drivers. You’ll hear every nuance in any song no matter how high you crank the volume. The drivers are made with a Liquid Crystal Polymer diaphragm with aluminum coating to really hammer home a beautiful sound. The goal is to get the truest form of the song possible and this combination gets the job done in a manner that no other headphones can replicate. 

How Sony Does It

We’ve heard about the astonishing sound these headphones generate, but it might help to understand a little bit more. Four silver-coated copper cables and independent ground and signal wires to each driver promote enhanced sound. Beat Response Control also allows you to regulate the air flow through acoustic ports in both ears. This allows the listener a more authentic sub-bass response to create an optimal acoustic environment. Along with a balanced cable, (which provides as you might surmise – balance), there is a 10-foot dual layer cable which delivers a rich bass response. 

Beautiful (and functional)

Thanks to an all metal look, the Sony Ultimate Hi-Res Headphones fit in with any style you flaunt. However, the metallic theme isn’t just about the aesthetics. With metal housing, metal hanger and metal headband, these headphones are remarkably durable and supply a richer sound. Leather, pressure-relieving ear pads provide around-the-ear comfort and seal tight the listening area. Acoustics are bounced back to your ears so you’ll pick up the tiniest sounds.
