You don't have to use the GameDAC at all—the headset supports 3.5mm connections, and you can just plug it into your device of choice. However, if you're not going to use the GameDAC unit, it might be worth springing for a cheaper headset in the SteelSeries Arctis line.

What does the GameDAC do?

The GameDAC transforms any PS4 or PC into a high performance audio source by bypassing the low fidelity, poor quality DACs found in typical console controllers, USB headsets, and PC sound cards.

Is Arctis GameDAC worth?

If you want to enjoy high-quality SteelSeries sound from your couch, the $329 Arctis Pro Wireless is probably worth splurging for. But if you game from your desk, can appreciate the value of a digital-to-analog converter and want stellar all-around sound, the Arctis Pro + GameDAC is worth the premium.
