SteelSeries' GameDAC has been a solid way to boost the quality of gaming audio (and virtually any other audio), but there's been a catch: to use it, you've had to buy an Arctis Pro headset rather than bring your own cans. That won't be an issue after today. The company is now selling the GameDAC by itself for $130 (€150), letting you plug in virtually any 3.5mm headphone set to use with your PC or PS4. You'll want a high quality set if you're going to make full use of the device's fidelity. If you have one on hand, though, the ESS Sabre 9018 DAC inside promises more distinct sounds, tighter bass, better positional sound (through DTS Headphone:X 2.0) and 24-bit/96kHz support from compatible sound sources. An OLED screen and physical controls let you fine-tune the output on a PS4.
