In daily use

Plug the UH38 Mono into any USB-A or USB-C port and join a Teams meeting in seconds—no drivers or software required. The in-line controller puts answer/end, volume, and mute at your fingertips, while the flexible boom microphone stays precisely positioned. When you are on a call, the red busylight and on-screen status update automatically, reducing interruptions. The built-in USB hub is a practical bonus for laptops with limited ports, letting you connect peripherals without reaching behind your desk. The 1.2-metre cable offers freedom to move, and the padded headband distributes weight evenly for all-day wear.
