High-Resolution ESS 9281 Quad-DAC

The ESS 9281 digital-to-analog converter (DAC) features QUAD DAC technology to provide lossless audio processing. Each of its four DACs devotes processing power to a subset of the audible frequency range, from lows, mids, highs to ultra-highs. The four signals are then combined, which produces clearer sound with an impressive 130 dB signal-to-noise ratio that's much higher than any other comparable device in the market. Hear every detail and enjoy crisp, clear sound for a true-to-life audio experience with ROG Delta S.

Built in MQA Renderer

Master Quality Authenticated (MQA) is an award-winning audio technology that delivers studio-quality sound and reveals every detail of the original recording. MQA Renderer technology in the ROG Delta S headset can connect to an MQA core signal – in global streaming service apps such as TIDAL – to complete the final "unfold" of an MQA music file and provide incredible audio quality.

High SNR in FPS Games

A high signal-to-noise ratio (SNR) is critical for gaming headsets, especially in FPS games. A higher SNR allows you to precisely pinpoint the origin of enemy footsteps, or hone in on the location of gunfire or explosions on the battlefield. With its quad-DAC design, ROG Delta S is capable of achieving an unprecedented SNR ratio of 130 dB, a level untouched by single-DAC gaming headsets.

AI Noise-Canceling Microphone

The ASUS AI noise-canceling microphone (AI Mic) has a dedicated processor designed to reduce over 500 million background noise while preserving vocal harmonics for crystal-clear in-game voice communication. Everyday 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 you can easily determine its status.

Soundwave Light Effects

An exclusive Soundwave light effect makes lights flash in sync with the sound of your voice.

Multiplatform Compatibility

The USB-C connector enables high-fidelity audio experiences with PCs, Macs, mobile devices and game consoles such as Nintendo Switch and Sony PlayStation.

Crafted for Comfort

Compared to oval ear cups, the ergonomic D-shaped ear cups of ROG Delta S closely match the shape of your ears, reducing unnecessary contact areas by up to 20%. The drivers in each ear cup are tilted by 12 degrees, closely matching the natural angle of human ears. The sloped design provides better comfort and also helps improve sound quality by enabling the audio signal to travel directly into the ear canal.

The cushions are made of 100% protein leather and fast-cooling memory foam, so you stay comfortable during long gaming sessions.

Instant Control at Your Fingertips

Intuitive control buttons on the ear cup let you instantly control volume, mute the microphone or adjust RGB lighting during gameplay.

Armoury Crate

Armoury Crate software offers extensive controls and an intuitive UI, so you can take full control of your audio experience. It makes it easy to create and apply audio profiles for a wide range of games and scenarios.
