ASUS ROG Delta

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 384 kHz. 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 20-150 Hz, mids from 150-5,000 Hz, highs from 5,000-20,000 Hz, and ultra-highs from 20,000-40,000 Hz. 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. Putting all the DACs in the headset helps achieve such a high SNR. Analog signals are susceptible to degradation, so it's best to keep audio in the digital domain as long as possible and away from interference. In the Delta, digital-to-analog conversions happen at your head, far from the electrical noise around the source devices like laptops and consoles. The Delta employs the same 50-mm Essence drivers as their 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.
