Audio Technica ATH-DSR7BT Wireless Over Ear Headphones

Audio-Technica

The future of sound is here with Audio-Technica’s ATH-DSR7BT Bluetooth headphones.

No wires, no loss. Redefining wireless audio, the Pure Digital Drive™ system reproduces the true sound quality of the music, delivering the original digital signal from source to driver without the need for D/A conversion that typically degrades sound quality.

  • 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 USB cable.
