Jabra Evolve 20 SE MS Mono USB C/A Single-Ear Headset USB Headphones with Microphone I am selling this because I purchased the wrong model number. It has never been used. ■ Quiet meetings even in noisy environments: The noise-canceling microphone blocks surrounding voices and noise. It delivers only your voice clearly, even in 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 such as initial settings. ■ No need to worry about the USB type of your computer: You can connect to both USB-C and USB-A with the main unit alone. You can rest assured even if the computer you use changes, such as when you are on the go or in a co-working space. ■ Comfortable to wear even for long periods of time: The "leather-type ear cushions" with a gentle touch to the ears and a lightweight design allow you to use it comfortably all day long. ■ Peace of mind because it is for business use: It is a certified model that has passed Microsoft's rigorous tests and is recognized for its compatibility with Microsoft Teams.
