The ATH-DSR7BT innovative over-ear Bluetooth wireless headphones supply your ears with Audio-Technica’s new Pure Digital Drive system, which allows the headphones to function without the sound-degrading digital-to-analog audio converter found in ordinary Bluetooth wireless headphones. With the use of new Trigence Semiconductor’s Dnote chipset, the ATH-DSR7BT headphones transmit the digital audio signal with the Bluetooth Wireless transmission and transfer the signal from source to the drivers, where the sound waves are created using the voice coil and diaphragm.
Audio-Technica Pure Digital Drive system, used in the ATH-DSR7BT wireless headphones, depends on exceptional and lightweight 45mm True Motion Drivers and purpose-built voice coils to bring spectacular detailed, high-resolution sound reproduction. Featured acoustic resistors are used to govern the airflow in front and behind the diaphragm to deliver a pure, well-balanced sound, and the entire driver assembly is housed within a layered aluminum structure that helps to minimize undesirable reverberance.
In addition, the Pure Digital Drive system allows the ATH-DSR7BT to transfer the signal from source to the driver, overcoming the sonic limitations of common Bluetooth wireless transmissions by supporting the 24-bit/48kHz Qualcomm® aptX™ HD codec. The ATH-DSR7 Bluetooth Wireless headphones also come with the 2.0 m (6.6′) USB cable that allows to reproduce high-resolution audio when connected to a PC or any other digital playback device.
Audio-Technica ATH-DSR7BT headphones feature volume control, a microphone and tap control for playing/pausing music or answering calls on a smartphone or any other device paired with the headphones. The LED indicators represent the codec in use, pairing and charging status – the battery provides approx. 15 hours of continuous use (up to 1000 hours in standby mode) of ATH-DSR7BT model.
