Fremont, California (December 9, 2020) — ASUS Republic of Gamers (ROG) today announced the ROG Delta S, the world's first MQA-enabled gaming headset. ROG Delta S offers the high-resolution ESS 9281 CODEC with QUAD DAC™ technology and integrated MQA support to deliver impeccably detailed, true-to-life audio. In addition to providing exceptional listening experiences, the ROG Delta S features the ASUS AI Noise-Canceling Microphone (AI Mic) for crystal-clear in-game voice communication, and a USB-C® connection and bundled USB-C to USB 2.0 adapter to enable full compatibility with a wide array of consoles and devices. Offering great audio experiences, clear voice communication and broad multiplatform compatibility, the ROG Delta S is for gamers, music lovers and anyone who appreciates an all-around good sound experience.

High-Resolution ESS 9281 CODEC with QUAD DAC Technology

The ESS 9281 CODEC with QUAD DAC technology on the ROG Delta S gaming headset provides lossless audio processing and exceptionally detailed sound. Each of the four DACs in the ESS 9281 CODEC devotes processing power to a subset of the audible frequency range, across lows, mids, highs to ultra-highs. The four signals are then combined to produce clearer sound with an impressive 130 dB signal-to-noise ratio—which is much higher than any other comparable device currently available on the market. With the ROG Delta S, users can hear every detail and enjoy crisp, clear sound for a true-to-life audio experience.

Built-in MQA Renderer

ASUS has begun collaboration with Master Quality Authenticated (MQA) which is the award-winning audio technology company. The ROG Delta S is the first achievement of this partnership and the world’s first MQA-enabled gaming headset. Through this collaboration, ASUS is delivering studio-quality music to gamers who are also audiophiles.

The award-winning MQA technology delivers studio-quality audio that unveils every detail of the original recording. The integrated MQA renderer in the ROG Delta S reads an MQA core signal, which is delivered by global streaming services such as TIDAL and Xiami Music, to reveal great audio quality.

“The partnership between ASUS and MQA is an exciting collaboration that has created the world’s first MQA-enabled gaming headset, ROG Delta S,” said Kris Huang, General Manager of the ASUS Gaming Gear and Accessory Business Unit. “This great partnership with MQA is allowing ASUS to continue to push boundaries and create the best headsets on the market. Gamers value impeccably detailed sound, and the MQA-enabled ROG Delta S gaming headset delivers supreme, true-to-life audio.”

ASUS AI Noise-Canceling Microphone and Incredible Lighting Effects

The ROG Delta S joins the same team as the ROG Theta 7.1, ROG Strix Go and ROG Strix Go 2.4 headsets in providing the ASUS-exclusive AI Noise-Canceling Microphone (AI Mic). The ASUS AI Mic has a dedicated processor that is designed to reduce over 50 million types of background noise while preserving vocal harmonics for crystal-clear in-game voice communication. Common background noises such as chatter, keyboard clatter and mouse clicks are reduced by up to 95%.

The AI Mic is unidirectional, detachable and certified by both Discord and TeamSpeak. An indicator light on the tip of the boom flashes red when the microphone is muted, so users can easily determine its status. The AI Mic is specially designed for users who need to communicate outdoors or anywhere with background noise. The feature can be controlled via ASUS Armoury Crate software, and can be easily turned off whenever necessary.

In addition to exceptional voice communication, the ROG Delta S provides a Soundwave light effect, which makes lights flash in sync with a gamer’s voice. This feature complements the customizable and integrated ROG Aura Sync RGB lighting in the ROG Delta S. All lighting effects can be quickly switched off via the headset buttons so users can easily set their own vibe.

Multiplatform compatibility

The ROG Delta S provides a USB-C connection that enables high-fidelity audio experiences with PCs, Macs, Nintendo Switch™, PlayStation® 5 and mobile devices, and the included USB-C to USB 2.0 adapter expands compatibility even further.


The Delta S will be available in North America from December 2020 with an MSRP of $199.99.
