Four hi-fi-grade ESS 9018 DACs (in one ESS 9218 DAC) provide lossless audio processing with each DAC devoting its 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 127-dB SNR that’s much higher than any device in the market. As a result, you can hear and place in-game sounds with pinpoint accuracy, letting you precisely judge enemy distance, direction of footsteps, gunshot locations and more. Hear every detail and enjoy crisp, clear sound for a true-to-life audio experience

Hyper-Grounding is ROG's exclusive technology, which utilizes a multi-layer PCB and a special layout design to prevent electromagnetic interference, resulting in pure, noise-free audio. Due to this innovative technology, ROG Delta is the world's first gaming headset with RGB lighting that is able to include an ESS Quad DAC and unlock its full potential to provide gamers rich, powerful sound unmatched by other gaming headsets.

With ROG Delta, the exclusive ASUS Essence drivers have been updated with Audio Signal Diversion technology, giving them a circular wall that helps separate high, low and medium frequency sounds, reducing interference between frequency ranges for purer and clearer audio. Additionally, the drivers feature a wide frequency response of 20–40kHz to provide incredibly strong bass and optimized gaming sound, so you'll hear every detail while enjoying an all-around immersive acoustic experience

Show your style with customizable Aura RGB lighting. ROG Delta leaves single-color lighting behind as the world's first gaming headset to feature rainbow circular RGB lighting. This captivating effect features seven independent lighting zones with dazzling multicolor cycling displays. Choose from over 16.8 million color combinations and six preset lighting effects.

Instead of a 3.5mm connector, ROG Delta features a USB-C connector and comes with a USB-C to USB 2.0 (Type-A) adapter, which allows it to connect with nearly every gaming platform, including PCs, consoles and mobile devices, letting you enjoy its class-leading performance, anytime, anywhere.

ROG Delta has ergonomic, D-shaped ear cups that more closely match the shape of human ears compared to oval ear cups, reducing the unnecessary contact area by 20% for a better, more comfortable fit, especially when the headset is worn for long periods.

ROG Delta provides two types of fit and feel for you to choose from based on your needs or preference. ROG Hybrid ear cushions, which combine protein leather and fabric mesh, are thicker, more breathable and provide a contoured fit, perfect for long gaming sessions. The protein leather cushions are comparatively thinner and softer, making them good for on-the-go use.
