The DSR9BT is the first audio-technica headphone to introduce the Pure Digital Drive™ technology. This technology doesn't work like most on the market, and could quite easily set the benchmark for premium headphones going forward.

In essence the signal is communicated via Bluetooth but stays in digital format right up until it hits the driver. The driver then converts this signal straight into audible energy. This removes the need for a DAC (digital to analogue converter) and additional hardware getting between the source and the listener. The result? Less distortion/ colouration and more clarity/ transparency.

The primary use for the headphones is wireless use, because with wireless you are granted access to 24-bit/48kHz high definition audio. However, if your run out of battery you can connect the headphones with a USB (type B) cable and listen that way.

Key Features

• 24-bit/48kHz when connected wirelessly
• 24-bit/96kHz when connected with USB wire (USB type B)
• Bluetooth 4.2 supports aptX HD, aptX, AAC and SBC codecs
• Touch control and volume switch for managing music playback and calls
• Microphone for calls/ note making/ smart phone activation etc
• Aluminium sliders for strength, build quality, adaptability, weight reduction and style
• Est 15 hours continuous play time
• Hard carrying case

Please note that the headphones do not have traditional headphone jack inputs, due to their revolutionary Pure Digital Drive™ technology the need for this old technology is defunct. Wired connection is possible, however it will have to be via the USB type B connection (running at 24-bit/96kHz). Having said that, their unique wireless technology allows you to listen at 24-bit/48kHz, therefore you only really want to be listening on wireless anyway!
