ATH-SR9

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 case.

About High-Resolution 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.
