Audio-Technica Pure Digital Drive system, used in the ATH-DSR9BT wireless headphones, depends on exceptional and lightweight 45mm True Motion Drivers and purpose-built voice coils to bring superlative fidelity and extended 5 Hz – 45,000 Hz frequency response. The driver’s 4-core twisted OFC-7N voice coil brings accurate control of the diaphragm displacement, and the resistor controls the airflow around the diaphragm to ensure smooth sound reproduction across the entire frequency response range. Audio-Technica ATH-DSR9BT 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 response.

In addition, the Pure Digital Drive system allows the ATH-DSR9BT 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-DSR9 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-DSR9BT 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-DSR9BT model.
