Cougar finally got around to releasing the Phontum Pro gaming headset to the market, having unveiled it way back at the 2018 Computex, and announced it in December 2019. The Phontum Pro is an upscale variant of the Cougar Phontum, featuring a USB DAC in addition to the 4-pole 3.5 mm jack input. When plugged into USB, a single cable provides audio I/O and ARGB LED illumination around the cans.

The Cougar UIX software provides Azalia-USB class audio drivers, and a centralized application for audio- and lighting control for the headset. As a pair of cans, the Phontum Pro is stereo, with a pair of 53 mm drivers. A C-Media Xear3D DSP provides virtual 7.1 surround. The drivers provide 20 Hz to 20 kHz frequency response, 98 dB ± 3 dB sensitivity, and 32 Ω impedance. The mic features 9.7 mm of active noise cancellation, 100 Hz to 10 kHz frequency response, and -47 dB ± 3 dB sensitivity. The mic stock is detachable from the rest of the headset.
