The Yealink UH42 Mono is a professional monaural USB-wired headset designed for users who need clear, focused calls while staying aware of their surroundings. Built around a 35 mm speaker with dynamic EQ, the UH42 Mono automatically switches between call and music modes for natural voice quality and detailed audio playback. The 1-mic AI noise cancellation isolates the speaker's voice and reduces ambient noise so calls stay clear and private.

Designed after hundreds of head shape evaluations and thousands of comfort tests, the UH42 Mono provides optimal stability and comfort for long-term wear. Weighing just 116 grams, its lightweight single-ear construction and durable materials make it the ideal choice for workers who spend their entire day on voice communications, while the included in-line call controller with LED indicators gives quick access to common call functions.

Plug-and-play USB-C connectivity (with USB-A adapter included) lets the UH42 Mono integrate seamlessly with mainstream IP phones, softphones, and PC devices on Windows and macOS. Hearing-protection technologies including Peak Block Protection (EN50332), Australian G616 Protection, and Daily Noise Exposure Protection safeguard users throughout the workday.
