Audio-Technica ATH-SR9 Sound Reality Over-Ear High-Resolution Headphones


Free Lifetime Technical Assistance


The ATH-SR9 over-ear headphones feature newly refined 45 mm
True Motion Drivers with bobbin-wound OFC-7N voice coils and a DLC
(diamond-like carbon) coating on the diaphragm to give you spectacular Hi-Res
Audio wherever you go. The headphones also employ Midpoint Mount Technology,
which ensures uniform space in front of and behind the diaphragm, and an
acoustic resistor in each driver that helps control airflow around the
diaphragm for smooth, natural audio reproduction across the entire frequency
range. The highly rigid construction of the aluminum housings, anchored by
several tapped screws, greatly reduces unwanted resonance. And the soft,
durable foam earpads and headband ensure a comfortable fit. 

The ATH-SR9 headphones come with two detachable 1.2 m (3.9′)
cables: one standard and one with an in-line controller and microphone to let
you easily answer calls and control music and video playback. Both cables are
equipped with A2DC (Audio Designed Detachable Coaxial) connectors at the
headphones for exceptional durability and optimized audio performance. The
headphones fold flat for easy transport in the included hard carrying

About High-Resolution Audio 

In Brief: The Move to Hi-Res Audio 

While many listeners may believe that high-resolution audio came along with the
introduction of the Compact Disc in 1982, constraints on the disc’s storage
space always prevented CD audio (standardized at 44.1 kHz/16-bit) from fully
and completely reproducing the original recorded sound. The advent and
subsequent popularity of MP3s only made this problem more pronounced – the
necessary compression of these files causes audio information to be lost, thus
greatly reducing the audio quality. But with lossless audio file formats,
faster Internet speeds, and storage space increasingly easy to come by (and in
ever-smaller packages), the push is on to create audio equipment capable of
capturing and reproducing true Hi-Res Audio, generally considered to be 96
kHz/24-bit or better. The Hi-Res Audio logo certifies that a product meets the
Hi-Res Audio standards. Per these standards, headphones must have transducer
frequency performance to at least 40 kHz. As a producer of these types of
audiophile headphones since 1972, Audio-Technica is well-positioned to provide
audio solutions that meet the demands of Hi-Res Audio media formats, allowing
for the full reproduction of their extended sonic characteristics.
