Yealink EHS40 Wireless Headset Adapter
PRODUCT DESCRIPTION
Yealink EHS40 Wireless Headset Adapter (EHS40 / 1300037) - 2 Years Local Warranty
Electronic Hook Switch for Jabra, Plantronics and Sennheiser Wireless Headsets
The Yealink EHS40 is an electronic hook switch (EHS) adapter that bridges Jabra, Plantronics (Poly) and Sennheiser (EPOS) wireless headset bases with Yealink IP phones. Once installed, incoming calls are signalled directly in the earpiece and you can answer or end calls from the headset itself — no need to touch the phone. It is the standard EHS solution for Singapore receptions, call centres and busy office desks where staff move around while on calls.
Remote Call Control on Yealink T4x, T5x and VP59 IP Phones
The EHS40 supports the Yealink VP59, T58W, T58A, T57W, T54W, T53W, T53, T48U, T48S, T46U, T46S, T43U, T42U, T42S and T41S (firmware version 83 or later). That includes popular Singapore office phones stocked by SourceIT such as the Yealink SIP-T54W and Yealink T43U.
Plug-and-Play USB Installation with Y-Cords Included
The adapter plugs into the USB port of a compatible Yealink phone for plug-and-play deployment, and provides RJ45 (8P8C) and RJ9 (4P4C) output ports for the headset base. Three brand-specific Y-cords — Jabra, Plantronics and Sennheiser — are included in the box, so most wireless headset bases connect without buying extra cables.
Local Stock and Support for Singapore Businesses
SourceIT keeps the EHS40 in local Singapore stock with a GST invoice and 2 years local warranty support — ideal for IT teams standardising on Yealink desk phones with third-party wireless headsets across the office.
