ATH-DSR9BT

Wireless Over-Ear Headphones Distributed by: Technical Audio Group $899 RRP

A few months ago, I received Audio-Technica’s ATH-DSR7BT ($599 RRP) for review.

Despite being initially disappointed with the physical build of the headphone, the audio capabilities were enough to win me over in the end. Not to mention the aggressively low-price tag.

The entry level ATH-DSR7BT left me curious about what the ATH-DSR9BT flagship model would bring to the table.

Would it remedy the issues I had with the ATH-DSR7BT? Would the sound be compromised as a result? Coming in at $899, the price is nothing to sniff at and in this price bracket, we’re in the major league now playing against fierce competition – such as the noise cancelling version of the Sennheiser Momentum 2.0 ($799 RRP), and the Bang & Olufsen BeoPlay H9 ($799 RRP).

So, with it’s ambitious price point and strong audio heritage, the Audio-Technica DSR9BT is pitching at a pretty high benchmark this time around. Will it meet the expectations?

Starting with Audio-Technica’s proprietary Digital Drive System, which does away with the traditional DAC system found in all other Bluetooth headphones. In its place, Trigence Semiconductor have stepped in with their flagship Dnote chipset, which acts as the “allin-one” Swiss army knife of portable audio.

With only one chip, the duties of both a DAC and amplifier are performed in one neat little package. This allows the signal path to remain digital, all the way from the source device, right up until it hits the drivers. Neat!

and an integrated high-performance magnet, built into the iron yoke at the rear of the driver.

On the playback front, the DSR9BT is at the cutting edge of codec compatibility - one of the few Bluetooth headphones I’ve reviewed that allow for APTX-HD playback. In addition to this, the usual suspects are here: APTX, AAC, SBC (enabling a Bluetooth playback resolution of 48kHz/24-bit). If you need to

Conclusion All the build quality issues I had with the DSR7BT are completely remedied with this release. This is a rock solid, well designed headphone, which is not only great to look at, but also comfortable.

Packed with acoustic technology, the sound of the DSR9BT is incredibly fast, with excellent treble clarity and a deep-reaching low end. The signature is very well balanced, and leans gently towards being bright.

I would recommend this headphone to anyone looking for a great looking and sounding wireless accompaniment for around the house.
