Purchased from Amazon on 2025/12/22, used for about an hour. I bought it, but the sound wasn't to my liking for gaming, as I mainly focus on audio. I'm selling it. It has a microphone jack, so it works well with gaming headsets. You can plug a 4-pole jack into the headphone side and use the sound normally, but use the included splitter cable when using the microphone. ✱All accessories are unused (as is common with Chinese products, there may be issues with the cables, but I haven't checked since they're unused). ✱If you don't need the outer box, the packaging size will change, and I'll lower the price slightly to reflect the difference in shipping costs. Please comment if you're interested.
