Are Plantronics CS540 and Savi W440/W740 Earpieces Compatible

Posted on November 9, 2012 by Stuart @ comfortcanada

In one of our previous Blogs we showed how the CS540 headset is compatible with Savi wireless products such as the Savi W740, and by inference, the Savi W440. Both use the same communication language (DECT) and provide the same clarity and similar range for voice communications. You can subscriber a CS540 earpiece to a Savi W440 USB dongle or Savi W740 base, and you can conference earpieces from both systems on a single call.

However, there are some differences in the earpieces and batteries for the CS540 vs Savi W440/W740 that are clarified in the following table.
