The Logitech Wired USB Headset with microphone for educational use provides digital stereo sound with a 85dB volume limit to protect students ears. This headset is simple to use; just plug the USB connector into any computer or laptop USB port. The on-ear design has thicker ear pad cushioning to help block out classroom noise, so students can focus. The left-side, microphone can be positioned to capture the student's answers clearly and minimize background noise. The padded headband easily adjusts and the non-PVC cable is knot and chew-resistant. Quickly sanitize this durable headset with any disinfectant or antibacterial cloth.
