It also comes with a type-A adapter for backwards compatibility to legacy ports. > Inside, the headset has a quad-DAC array that splits the sound, with each DAC devoted to a frequency range: lows from 20-150Hz, mids from 150-5,000Hz, highs from 5,000-20,000Hz, and ultrahighs from 20,000-40,000Hz. These four signals are then combined, and Asus says the resulting SNR (signal to noise ratio — a comparison of the level of signal power to the level of background noise) is 127dB. Complementing the DACs are 50mm Essence drivers, the same seen on Asus’ Strix Fusion gaming headset.
