Audio-Technica today announced its SonicPro ATH-MSR7 Over-Ear Hi-Res Audio Headphones, a pair of smartphone-compatible headphones using a 45 mm driver with a lightweight, highly responsive voice coil and diaphragm. The ATH-MSR7’s Multi-Layer Air Damping Technology utilizes a two-layer aluminum/magnesium housing that provides a lightweight yet rigid structure for the drivers to reduce unwanted internal vibrations that could color the sound. Within the multi-layer structure are three precisely placed air vents that control the airflow to provide greater dynamics and sonic impact. The housing is specially shaped to “mirror” the physical structure of the ear to enhance low-frequency sounds.

In addition, the ATH-MSR7 incorporates a mesh acoustic resistor that improves high-frequency response, and a low-frequency acoustic resistor for extended, accurate bass. The sonic result is a smooth, richly detailed, powerful and spacious sonic presentation that completely immerses listeners in the high-resolution audio experience.

Complementing its superlative sound quality, the ATH-MSR7 is designed for total comfort. Its cushioned, soft, memory foam earpads fit securely yet comfortably around the ears and its flexible swivel design and padded headband facilitate a perfect fit for any wearer.

The ATH-MSR7 is ideal for use with any music system or playback device whether it’s a home stereo, laptop, portable music player or smartphone. The headphones are supplied with a detachable 4-foot smartphone-compatible cable with an integrated controller and microphone that let the wearer answer phone calls and control music/video playback from compatible smartphones and other devices, including AndroidTM-based systems, iPhone, iPad and iPod. The ATH-MSR7 also comes with a standard 4-foot and 10-foot cable and a carrying pouch.

The $250 Audio-Technica SonicPro ATH-MSR7 Over-Ear High-Resolution Audio Headphones ship in March 2015. Here are the detailed specs.
