Yealink Headset Adapter EHS40 - Wireless Headset Connectivity for IP

In this review the Yealink Headset Adapter EHS40 is presented as a focused accessory for office users who need reliable wireless headset integration with Yealink phones. The biggest reason to consider it is simple: it enables remote answer and call termination from compatible Jabra, Plantronics and Sennheiser wireless headsets, bringing headset convenience to a wide range of Yealink SIP phones without complex setup. For teams that already use wireless headsets and Yealink handsets, it is a compact way to add seamless call control and preserve desktop mobility.

Key Features

• Phone compatibility: Works with a long list of Yealink SIP phones so IT teams can standardize on one adapter across models.
• Wireless headset support: Integrates with Jabra, Plantronics and compatible Sennheiser headsets to allow remote call control from the headset itself.
• Multiple headset outputs: Provides an RJ45 output for GN/Jabra/Sennheiser and a 3.5mm output for Plantronics to support different headset connectors.
• Plug and play: Requires minimal configuration, letting users answer and end calls through the headset without telecom engineering effort.
• Call signaling in headset: Incoming calls are signaled in the headset earpiece so users do not have to look at the phone to know a call is ringing.

Who It's For

The EHS40 is aimed at office users and contact center agents who already have Yealink SIP phones and want to use wireless headsets from mainstream brands. It is most valuable where desk mobility and simple remote call control are priorities, such as shared workstations, hot desks, and agents who move between calls.

Those who should look elsewhere include users with unsupported headset models or non-Yealink phone platforms; also, anyone requiring advanced audio processing or built-in conferencing features should consider a dedicated DSP-equipped device instead.

Pros & Cons

Pros

• Easy setup and true plug-and-play integration for most Yealink phones, reducing deployment time.
• Broad compatibility with Jabra and Plantronics wireless headsets, allowing flexibility in headset choice.
• Multiple output connectors (RJ45 and 3.5mm) cover the common headset wiring standards in offices.
• Remote call answer/end and in-ear call signaling add practical convenience for daily use.

Cons

• Some users report mixed functionality or garbled audio with certain phone/headset combinations, so results can vary by firmware and model.
• Sennheiser compatibility requires the headset DW-Office series to be on recent firmware, adding a dependency on headset updates.
