This is the SteelSeries external DAC "GameDAC Gen2". It supports PC and PS5, allowing you to build a high-quality gaming audio environment. I was using it for FPS games, and it works without any problems. Volume dial, mute, equalizer operations, etc. are all normal. The box, instruction manual, and included cables are all included. There are no noticeable scratches or stains, and it's in relatively good condition. Compatible models: ・PC ・PlayStation 5 (※Xbox is not supported) Condition: ・Operation confirmed ・Initialized Notes: Please understand that this is a used item, so there may be minor signs of use. Instant purchase is OK, and I will consider price negotiations within reasonable limits.
