practically commonplace in the pro audio
What I thought would be a simple process, visiting retail stores to audition headphones, and eventually deciding turned into a deep dive down the rabbit hole. Like many other headphone fanatics, my Head-Fi journey really began when I eventually resurfaced with the trusty Audio-Technica ATH M50 in hand. The M50, at least for me, acts like a gateway drug - opening the door to a lifelong pursuit of better audio. Audio-Technica started off in 1962 as a phonograph cartridge manufacturer. The founder, Hideo Matsushita, sadly passed away in March of 2013. During the company’s 40th anniversary in 2002, Hideo looked back on the very beginning of the company. He was quoted saying: “I came to Tokyo at age 32, and, thanks to an introduction by my uncle, went to work for the Bridgestone Museum of Art. At the urging of the museum’s director, I began organizing LP concerts. These were much more successful than anyone imagined. After a decade at the Bridgestone Museum, I struck out on my own and established Audio-Technica in 1962.” His son, Kazuo Matsushita, is still the president today.
scene used in both studio and live scenarios. They were even one of the first companies to ever produce a headset microphone. Their headphones are also highly renowned, and have even achieved “cult-like” status in some circles. They have a headphone range for every conceivable category, including DJ, pro audio, Hi-Fi, noise cancelling, sports, gaming, and even communications headsets. At the beginning of 2017, Audio-Technica unveiled their latest wireless headphones at the CES Show in Las Vegas. The range consisted of two models: ATH-DSR9BT, and ATH-DSR7BT. Both releases are over-ear wireless models, featuring Audio-Technica’s latest proprietary Bluetooth system, 45mm drivers, and are packed with acoustic wizardry. Taking a closer look at the ATH-DSR7BT, it comes in at $599 locally. Staring down the barrel of releases such as the Sennheiser Momentum Wireless 2.0 ($799 AUD), Bang & Olufsen H7 wireless ($699 AUD), and the Bowers & Wilkins P7 Wireless ($600 AUD), one can’t help but think the price point has been strategically set. Even so, $599 is nothing to sneeze at in the Bluetooth over-ear game.

producing some awkward audible creaking. The noise is frequent and loud, and I can only hope it will subside over time. The culprit isn’t just one single part; all moving parts (and even the headband) will groan when adjusted. The headphones don’t fold, either. This is a tricky sell for a Bluetooth headphone, as they will inevitably eat up an uncomfortable amount of room when being stored.
The 45mm drivers feature multiple bobbinwound voice coils and are kept completely isolated from the electric circuitry contained in the cups. They are also angled inwards, which is said to enhance the listener’s perception of soundstage and imaging. The DRS7BT does not transmit audio via Bluetooth in the same way a typical Bluetooth headphone does. Instead of utilising a

In use Upon powering them on, the LED indicators on the outside of the cup light up, and will assist with the pairing process. Sound effects played through the cup indicate the headphones current pairing status. I noticed a somewhat strong clamping force when putting them on for the first time. It did weaken slightly over the following days, but remained an issue for the duration of my use. When moving about, and as mentioned, the headphones will lightly creak and squeak. It’s just enough to invade the quiet moments in your music and movies. Pairing via NFC was incredibly simple, and the fact that I could potentially pair these with up to 8 devices is mind-numbing. I’m yet to come across another Bluetooth headphone that can do that. Connected via Bluetooth there is some noticeable background hiss. This may vary depending on what device and Bluetooth version your source is equipped with. When Bluetooth isn’t an option I was easily able to connect the device via USB without any need to install additional software or drivers. I also noticed that this connection method has a much lower noise floor so after running through all the tests it became my preferred connection method. When in Bluetooth mode, the lights on the outside of the headphone not only show battery life, but will indicate which profile/codec is being used. A full battery charge will take around 5 hours.

Conclusion Smartly priced to come in cheaper than their competitors, the beautiful, airy and accurate sound signature and fantastic acoustics of AudioTechnica’s ATH-DSR7BT presents great value. Build quality and lack of real isolation holds them back from being a fantastic travel buddy. Perhaps the bigger brother, the DSR9BT, might make up for these shortcomings.
