Asus Launches ROG Delta USB-C headset - Claims 127 dB SNR

The ROG Delta Type-C headset is the latest addition to a growing line of audio devices from ASUS. The Delta is bridging PCs and mobile devices with a future-proof connector that works with the latest examples of both, like the Strix SCAR II and Hero II laptops and the ROG Phone.

Adopting USB Type-C allows the ROG Delta to plug in to a broad range of next-gen devices. The reversible jack is easy to connect, while the digital interface carries a pristine audio signal to the headset. Older devices are supported via the included Type-A adapter, which ensures backward compatibility with legacy USB ports.

Sound clarity is excellent no matter which source you choose. The ROG Delta uses ESS Sabre silicon capable of pumping out high-definition audio at up to 32 bits and 384kHz. While most stereo headsets rely on a single DAC, the Delta has four. Each DAC devotes its processing power to a subset of the audible frequency range: lows from 20-150Hz, mids from 150-5,000Hz, highs from 5,000-20,000Hz, and ultra-highs from 20,000-40,000Hz. The four signals are then combined, which produces clearer sound with an impressive 127-dB SNR that’s much higher than typical mobile devices and even high-end motherboards. The quad-DAC array brings to life audio across different kinds of content, and it can even help gamers pinpoint specific sounds and positional cues by reducing background noise.

The Delta employs the same 50-mm Essence drivers as our Strix Fusion series. In concert with the DACs,  they immerse you in rich stereo sound. Stereo consumes less power than surround sound, making the headset ideal for smartphones, laptops, and tablets, where sustaining battery life is vital. Most people turn off virtual surround sound anyway, and pro gamers avoid it entirely. The Delta still works with software-based surround sound, including the virtualization built into many games. It’s also compatible with the new effect injection feature available in the latest Sonic Studio III software on our Strix Scar II and Hero II gaming laptops. To improve acoustic isolation, the interior walls of the cushions are lined with synthetic leather. That can get steamy during intense matches, so the rest is covered by a breathable mesh fabric to stave off sweat. The Delta also comes with a second set of cushions wrapped in synthetic leather throughout, so you’re covered for both warm and cool weather.
