Audio Technica ATH-SR9 Over-ear high-resolution Audio Headphones

 

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 cables: a standard 3m cable and a 1.2m cable with 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 optimised audio performance. The headphones fold flat for easy transport in the included hard carrying case.

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 (standardised 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.
