Yealink EHS40 Interface adapter

What it is

The Yealink EHS40 is an Electronic Hook Switch (EHS) interface adapter. It connects a compatible wireless headset to your Yealink desk phone via USB Type-A, letting you answer, end, and manage calls directly from the headset — no need to touch the phone.

Who it's for

Anyone using a Yealink T-series desk phone who wants to pair it with a wireless headset. It's a common add-on for office workers, receptionists, and call handlers who need hands-free operation throughout the day. Compatible phones include the T58A, T57W, T54W, T53W, T53, T48S, T46S, T42S, and T41S.

Why it's good

Without an EHS adapter, a wireless headset can play audio but can't control call functions on the phone. The EHS40 bridges that gap cleanly. It's a small, low-cost accessory that makes a real difference to daily workflow — especially in busy office environments where picking up the handset every time isn't practical.

When to choose it

If you have a compatible Yealink desk phone and a wireless headset that supports EHS, this is the adapter you need. Check your headset brand's compatibility list before ordering — not all wireless headsets support EHS control.
