Our USB-C Headphone w/ Boom Mic has everything you may need for a school or office setting. The USB-C connection makes it compatible with all modern Type-C devices, including new smartphones, but we also included a USB-A adapter for your convenience. The included boom mic is detachable, that way it is not always in the way, and there is also an inline mic that can be utilized. The customizable polybag that is included is perfect for the classroom, ensuring that each student keeps track of their own device.
