The Yealink EHS35 is a plug-and-play headset adapter that provides a technical interface between Yealink T3X-series IP phones and the Yealink WH62 or WH63 DECT wireless headset. With the EHS35 connected, users gain full remote call control directly from the headset—answer, reject, hang up, hold, mute, switch between calls, and adjust volume—without ever touching the desk phone. This is ideal for receptionists, call centers, and any professional who needs to step away from the desk while staying on the call.
Installation is effortless. The EHS35 connects to the desk phone's RJ9 (4P4C) headset port on one end and the WH62/WH63 base station's Micro USB port on the other. No power adapter, drivers, or configuration software is needed—the adapter is recognized automatically. WH62/WH63 firmware must be version 104.434.0.15 or later to ensure compatibility (verifiable via Yealink USB Connect on PC).
While full remote call control is available on Yealink T3X-series phones, the EHS35 also provides audio-only connectivity (without remote control) when used with Yealink T4X/T5X-series phones and third-party desk phones from Avaya, Poly, Snom, Grandstream, Fanvil, Mitel, and Unify. The result is a versatile, low-cost adapter that extends the value of WH62/WH63 wireless headsets across a wide range of office phone deployments.
