The Yealink YHS34 Lite Mono is a professional over-the-head, single-ear analog wired headset designed for office workers, SOHO users, and call center staff who prefer breathable foamy ear cushions over leather. Featuring a Quick Disconnect (QD) to RJ9 plug-and-play setup, the YHS34 Lite Mono is fully compatible with the entire range of Yealink enterprise IP phones, allowing the connected phone to automatically optimize acoustic parameters for crystal-clear conversations right out of the box.

Built around a high signal-to-noise-ratio 28 mm speaker with an independent cavity design, the YHS34 Lite Mono delivers wideband HD Voice audio for richer, clearer calls. The uni-directional ECM noise-canceling microphone combined with passive noise cancellation reduces background noise so only the speaker's voice is transmitted. ActiveProtection technology safeguards users from sudden acoustic injury, while a 320° bendable boom arm makes adjustment easy and durable.

Engineered for all-day comfort, the YHS34 Lite Mono uses ultra-lightweight materials and soft foamy ear cushions for excellent breathability, weighing 10–30% less than comparable conference headsets. Its single-ear design lets users stay aware of their surroundings while making calls, making it ideal for receptionists, contact-center agents, and busy office workers who spend long hours on the phone.
