  • Overview

    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.

    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 driver’s 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 housing’s 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 indicators allow you to easily monitor pairing and charging status, battery level, and the codec currently in use. The headphones’ internal lithium polymer battery provides approximately 15 hours of continuous use (up to 1000 hours in standby mode) and can be recharged using the included USB cable.

    About High-Resolution Audio
    In Brief: The Move to Hi-Res Audio
    While many listeners may believe that high-resolution audio came along with the introduction of the Compact Disc in 1982, constraints on the disc’s storage space always prevented CD audio (standardized at 44.1 kHz/16-bit) from fully and completely reproducing the original recorded sound. The advent and subsequent popularity of MP3s only made this problem more pronounced – the necessary compression of these files causes audio information to be lost, thus greatly reducing the audio quality. But with lossless audio file formats, faster Internet speeds, and storage space increasingly easy to come by (and in ever-smaller packages), the push is on to create audio equipment capable of capturing and reproducing true Hi-Res Audio, generally considered to be 96 kHz/24-bit or better. The Hi-Res Audio logo certifies that a product meets the Hi-Res Audio standards. Per these standards, headphones must have transducer frequency performance to at least 40 kHz. As a producer of these types of audiophile headphones since 1972, Audio-Technica is well-positioned to provide audio solutions that meet the demands of Hi-Res Audio media formats, allowing for the full reproduction of their extended sonic characteristics.

    Great first use of this technology

    Comments about Audio-Technica ATH-DSR9BT Wireless Over-Ear Headphones with Pure Digital Drive:

    Fantastic DAC free sound. I've used many high end headphones and these have great detail, soundstage and separation. Flat with just the right amount of bass and realistic treble.

    I use a USB to C adaptor into my MacBook, BitPerfect with iTunes and upscale to 24/96. Great AAC sound over bluetooth with iPhone too.

    Controls could be better, as could the cable connection to the headphones - waiting for the flexible cover to fall off.

      Comments about Audio-Technica ATH-DSR9BT Wireless Over-Ear Headphones with Pure Digital Drive:

      Got these while in Japan last month while looking for wireless headphones that could replace my B&W P7s that I lost (but were too small for my ears) and the B&O H9s that I had just returned since they hurt so much to wear (the headband KILLS!).

      All in all, love these cans, they're the best I've had so far. Sound is crisp, deep, and powerful. Isolation is nice, even though there's no active noise cancellation. They're also super comfortable.

      What I don't like:
      - Why use a standard USB port but make the entrance so small that none but the supplied cable fits? I have a bunch of Anker kevlar cables throughout my house and office (both USB and lightning) so that I can plug in my devices wherever and not worry, but these cans don't work with them (or any of my other cables for that matter). So yet another cable that I have to manage :(
      - Walking with the cans makes rattling noises since lots of the outer materials are chintzy. Specifically, the volume button rattles.
      - The cans make squeaky noises from plastic rubbing on plastic when you move the ear cups.
      - The controls are terrible. It's really hard to find the pause / unpause button since it's just a plastic window that responds to touch. The placement is super awkward. The cans have their own volume, separate from your device. Adjusting the volume on the cans does not adjust the volume on your device, so you have two places to turn up / down potentially. Pressing and holding volume up / down goes to previous / next track. No, I want to make it louder, not go to the next track, ugh!
      - 0/5 calls were successful with the cans since the mics are terrible...thankfully I don't make many calls!

      Overall, since for me comfort & sound quality are the most important thing, these are a total win. I can live with the other parts and realize that folks haven't made a perfect device yet. I wish that AT checked out the B&W P7 for example of how to do buttons...

      • Q:

        The only main difference compared to the DSR7BT is that the 9BT has voice coil. Also the 7bt supports bluetooth 4.2 and 9bt only supports 4.1(just wondering why 9bt has older version) ..

        i mean both of them are using the same Pure Digital Drive system and the dnote chip.

        IS the price difference only due to the voice coil OFC-7N?

        • Staff Reviewer

          A:

          Thank you for your inquiry. Both are version 4.2.

          Along with the voices coil material differences between the 7 and 9 (single on 7 and quad on 9 OFC-7n ) the support power feedback circuit for the digital control is much different due to the VC construction. The DSR9 requires the this control circuit for all four coils to regulate power so distortion can be eliminated.

          Headphone material and construction are also a key difference.

          Thank you for your inquiry. The USB cable included with the headphones can be used for either charging the headphones, OR for plugging into a USB Audio port. Other than that, the headphones will need to connect to a device wirelessly.
