Wireless Over-Ear Headphones with Pure Digital Drive

The ATH-DSR7BT over-ear wireless headphones gift your ears
with Digital Sound Reality. These innovative headphones feature
Audio-Technica’s new Pure Digital Drive system, allowing them to operate
without the sound-degrading D/A converter found in conventional wireless
headphones. By utilizing Trigence Semiconductor’s Dnote chipset, the ATH-DSR7BT
headphones are capable of receiving a Bluetooth wireless transmission,
processing the digital audio signal and transferring it to the drivers where
the digital pulses of the chipset move the voice coil and diaphragm forward and
backward to create the sound waves heard by the listener.

The Pure Digital Drive system likewise depends on
re-engineered 45 mm True Motion Drivers, which feature specially designed
diaphragms and lightweight, bobbin-wound voice coils to deliver incredibly
nuanced, high-resolution sound reproduction. A pair of acoustic resistors
controls the airflow in front of and behind the diaphragm to ensure a natural,
balanced sound, and the entire driver assembly is housed within a layered
aluminum structure that minimizes unwanted resonance and isolates the electric
circuitry from the housing’s acoustic space, resulting in optimal phase and
transient response.

The Pure Digital Drive system also enables the ATH-DSR7BT to
overcome the sonic limitations of conventional Bluetooth wireless transmissions
by supporting the 24-bit/48kHz Qualcomm® aptX™ HD codec. (aptX, AAC and SBC
codecs are also supported.) The headphones can reproduce Hi-Res Audio when
connected to a computer or other digital playback device via the included 2.0 m
(6.6′) USB cable.

The ATH-DSR7BT is equipped with a microphone, volume control
and simple tap control for answering/ending calls and playing/pausing music on
a smartphone or other device. Three LED indicators allow you to easily monitor
pairing and charging status, battery level, and the codec currently in use. The
headphones’ internal lithium polymer battery provides approximately 15 hours of
continuous use (up to 1000 hours in standby mode) and can be recharged using
the included USB cable.

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
