Looking at two similar headsets, and wondering which one might be for you? We’re here to give you the facts to help you make the best decision for your use case! Let’s go over the two DECT offerings of the Yealink WH63 vs Poly Savi 8445.


If you’re looking for a single ear, earbud style headset that can connect to both desk phones and PC, look no further. Both are DECT headsets. Both of these models offer easy connectivity, flexibility, and a lightweight wearing style. So, what sets one apart from the other?

Yealink WH63

Yealink’s earbud style headset has both great sound, and great simplicity. If you’re looking for a plug-and-play headset that connects to a desk phone via USB A, this is a solid choice.

Things we love about it:

  • Super easy to set up. Plug the headset into your PC and the desk phone, then plug it into power, and you’re ready to go. Incoming calls from both sources get routed seamlessly to the headset. Easily add the EHS60 to make the headset compatible with Cisco and Avaya phones!
  • Able to pair multiple headsets to the same base for training. Connect two to four headsets together on the same base.
  • Charges quickly. Which is good, as the dock is efficient.
  • Comes in a UC and a Microsoft Teams version. Features a dedicated Microsoft Teams button for easy use.
  • The earbuds are some of the most comfortable we’ve used. They also come in a variety of shapes and sizes.

Things that could be improved:

  • Battery life could be better. 7 hours isn’t the greatest talk time.
  • Volume controls use a touch-slide movement on the ear, which can be tricky. Learning to slide your finger along the earpiece takes some getting used to.
  • Device updates handled through the Yealink USB Connect app. Yealink’s proprietary app is needed to change any of the settings within the headset.

Poly Savi 8445

Poly’s updated Savi 8400 series offers a revamp of their previously popular S8245 headset paired with a slimmed-down base. The new Savi 8445 comes with some updated features to make your desktop more seamless than ever.

Things we love about it:

  • Slimmer desk footprint. Takes up less desk real estate!
  • Change headset settings easily. Headset setting changes can be made from the scroll wheel on the base, without the need for an app. [However, device updates need to be made through the Poly Lens app.]
  • Comes with a second battery for extra talk time. Included with the package is a USB charge cable for the battery, so you can take it anywhere!
  • Multiple wearing styles for a tailored fit. Wear this headset on your ear, as an over-the-head style, or behind your neck.
  • Offers Bluetooth connectivity for use with mobile devices. Pair your phone to the base and manage calls from your headset!

Things that could be improved:

  • The screen wheel system takes some getting used to. The LED screen shows device status and the wheel is how you navigate the screens to change settings, but the combo can be cumbersome.
  • Keeping the headset connected to the PC line is cumbersome. The base tends to want to keep the main line a priority, and if you’re switching between desk phone and PC it can cause a delay between the two connections.

So which do I choose?

It comes down to what you need it for:

  • If you need Bluetooth connectivity, go with the Savi 8445.
  • Looking for a plug-and-play option for primarily PC with some desk phone? Yealink WH63 is your best bet.
  • Is cost your biggest concern? Then Yealink’s WH63 is going to be ideal.
  • Longer battery life? Savi 8445 wins on that front.
