Audio Technica DSR9BT Wireless Over-Ear Headphones with Pure Digital Drive
Description
Please note this item is ordered on demand from the supplier and may take longer than our usual 2 - 4 working days to arrive. The ATH-DSR9BT over-ear wireless headphones employ Audio-Technicas 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 Semiconductors 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. The Pure Digital Drive system likewise depends on a re-engineered 45 mm True Motion Driver which features a lightweight diaphragm with DLC (diamond-like carbon) coating for superlative fidelity and extended 5 Hz - 45 000 Hz frequency response. The drivers 4-core twisted OFC-7N voice coil provides precise control of the diaphragm displacement and an acoustic resistor controls the airflow in front of and behind the diaphragm to ensure smooth natural audio reproduction across the entire frequency range. The entire driver assembly is housed within a layered aluminum structure that minimizes unwanted resonance and isolates the electric circuitry from the housings acoustic space resulting in optimal phase and transient response. The Pure Digital Drive system also enables the ATH-DSR9BT 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-DSR9BT 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 ...
