I purchased this and used it a few times, then stored it at home. There are no noticeable scratches. It works without any problems. Quiet meetings even in noisy places: The noise-canceling microphone blocks surrounding voices and noise. It delivers only your voice clearly, even from noisy places. Start meetings immediately by simply connecting via USB: Simply plug the USB into your computer for easy setup. No need to worry about troublesome preparations like initial settings. No need to worry about your computer's USB type: The main unit can connect to both USB-C and USB-A. You can use it with peace of mind even if the computer you use changes, such as when you're on the go or in a co-working space. Comfortable fit even for long hours of use: With "leather-type ear cushions" that are gentle on the ears and a lightweight design, you can use it comfortably all day long. Peace of mind because it's business-oriented: It's a certified model that has passed Microsoft's rigorous tests and is recognized for its compatibility with Microsoft Teams. It can also be used with other conference platforms.
