EHS40 Reset - Sennheiser

Updated by Kamika Royal on Sep 9, 2024

Yealink EHS40 for Sennheiser wireless headsets


Before we jump into this reset, have you tried rebooting your phone? It's super-easy!

  • Just press and hold the X button on your Yealink telephone until it prompts you to reboot
  • Once the phone comes back up, test out your headset! This often works with no reset needed!

If that didn't fix things for you, here is a reset you can try:

How to do an EHS reset on EHS40: Sennheiser Wireless

  • Unplug the power from the back of the headset base (yellow sticker) and USB (orange sticker, may not be plugged in)
  • Unplug the cord in the green phone port in back of base
  • Head to the back of the phone and unplug the USB (may be in back or the side of phone)
  • Next, plug everything back in, but in reverse order: USB-->phone port-->power
  • Test out your headset
