The ATH-DSR9BT over-ear wireless headphones employ Audio-Technica’s new Pure Digital Drive system, which allows the headphones to operate without a sound-degrading D/A converter that conventional wireless headphones rely upon. Instead, the ATH-DSR9BT utilizes Trigence Semiconductor’s Dnote chipset to receive the digital audio signal from a Bluetooth wireless transmission, process and transfer it to the driver 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. 

  • Exclusive Pure Digital Drive system keeps audio signal completely digital from source to driver for exceptionally pure sound
  • Dnote chipset controls driver amplitude directly with digital signals – no D/A converter required
  • Compatible with Qualcomm aptX HD, aptX, AAC and SBC codecs, enabling wireless transmission with a resolution up to 24-bit/48kHz
  • Exclusive 45 mm True Motion Driver, featuring 4-core twisted OFC-7N voice coil and diaphragm with DLC (diamond-like carbon) coating, extremely accurate audio reproduction with extended high frequencies
  • Housing’s dual-layer isolation structure keeps the electric circuitry separate from the acoustic space for optimal phase and transient response
  • Acoustic resistor controls airflow inside the diaphragm housing, yielding more natural sound
  • Mic and volume/control switch are built into the earcup for convenient control of smartphones and other Bluetooth wireless devices
  • NFC (Near Field Communication) functionality enables touch pairing with NFC-compatible Bluetooth wireless technology devices
  • Remembers the last eight Bluetooth wireless devices paired
  • LED indicators in the earcup display pairing and charging status, battery level, and the codec currently in use
  • Heat-reactive soft foam earpads and an easily adjustable leather headband provide a comfortable fit with outstanding sound isolation
  • Internal battery provides approximately 15 hours of continuous use (1000 hours on standby) on a full charge
