Product Review – Plantronics SAVI W420-M

Every now and again I have the pleasure of taking a new (often simply new to me) piece of hardware for a test drive. Over the last few weeks I have been trialing the Plantronics SAVI W420-M. From what I can tell the M likely stands for Microsoft as this is the W420 that’s optimized for Microsoft Lync.


  • Optimised for Lync
  • Binaural (two-ear) Headset Design
  • Connectivity Computer only via USB dongle
  • Using DECT 6.0 between dongle and headset
  • Range – up to 90 meters, making it very portable
  • One touch call control
  • Stereo, Wideband Audio
  • Noise cancelling – great for reducing surround noise
  • Its really light, at around 94 grams

What I liked..

This headset is fully adjustable, the speakers swivel both inward and outward for the perfect fit. I seem to have developed a sensitivity for the more intrusive in-ear designs and tend to stay away from wearing that sort of design for extended periods of time.

I also like the way it fits into a decent carry case, just throw in the USB dongle and you are off.

I have always preferred overhead styles compared to overear. Of course being overhead, wireless and stereo it had my attention from the get go. Once I had worn it for a few consecutive days, listening to music in-between calls I noticed how light and comfortable it really is. Try wearing any headset for a few full 8 hour plus days and you will quickly separate the men from the boys.

I also like how I can just drop it to around my neck when having to step away for a minute without feeling conscious about wearing a headset. It actually feels rather funky to wear. My 18 month old son wore it for a full Skype discussion with Gramps via skype. I was really surprised as he really dislikes having things on his head. It fit him very well too, once I had made a small adjustment. I had to bribe him with a treat to get my headset back..


Perhaps a portable charger or charge over USB option can be added to this excellent headset. Carrying around the charging kit is the only negative IMHO.

Overall I give it a 9/10. I have to add that this is very fast becoming my most used headset, second only to my Voyager Legend.


About Paul B

My name is Paul Bloem and I am employed at Lexel Systems in New Zealand as a Principal Consultant for Unified Communications. I have been working on enterprise voice solutions for over 20 years. My first 10 years were spent working for a Telco in South Africa (Telcom SA). This is where all the groundwork happened as I was exposed to just about every aspect of telecommunication you could imagine. I develop an interest in PBX technologies and eventually became the go-to guy. Next, I had a 10 year run at Siemens South Africa, most of my time there was as a Technical Trainer. During this time VoIP hit the world stage, I had the privilege of introducing VoIP both as H.323 and later SIP across the Siemens HiPath 4000 solution stack. In 2008 I immigrated to New Zealand with my newly attained MCSE, I was ready to go where no PBX Techie had gone before. I was employed to explore OCS 2007 and that was pretty much the beginning of the end for me. I have been working on OCS and Lync ever since. My current role focuses exclusively on Lync and associated technologies.. That includes pre-sales, consulting, architecture and design, training and support. I even get to play in the development space from time to time - focus on play ;-) I was nominated as a Microsoft VTSP for Lync early in 2013 and also awarded Microsoft's MVP award for Lync in 2014.
