Over All Rating Reviews :
The unit has excellent range, and I suffered no loss of audio quality at all when moving anywhere in my house, even with a WiFi network active.
Compared to the Plantronics CS50/CS55, the Jabra GN9350e comes out on top, for the following reasons:
-Jabra has better more natural sounding audio quality when you speak, with better frequency response. Plantronics headsets make your voice sound somewhat tinny and muffled by comparison.
-Jabra has a MUCH better speaker in the earpiece than Plantronics. The Jabra earpiece has pretty good audio quality; not as good as a wired headset, but pretty good. The sound quality you hear in the Plantronics headset is just bad.
-This unit will work with both a PC and a DECT cordless phone. The Plantronics CS50 is PC only, but the CS55 can do DECT.
-If you don't have a DECT phone, this unit can also hook into any standard phone that has a corded handset. Plantronics can't do that.
Audio quality when using it with a normal phone is basically perfect.
Some nitpicks: I didn't find the leatherette ear cushion comfortable. You'll want to swap it out for a foam one. Also the included cord for hooking it to your phone necessitates it being right next to the phone. Also, the USB cable is short and mini-USB on the base-unit end, so if you need a longer cable you'll need to find one elsewhere. It would be nice if they included more "over-the-ear" earpieces like Plantronics does, but I find them uncomfortable and use the over-the-head ban anyway.
One last thing: Although this unit works great with normal phone and Skype, both this unit and the Plantronics have degraded audio quality when using Teamspeak. After extensive testing, I can definitely tell you it's a Teamspeak specific issue; a wired headset will give you much better speaking-audio quality with TS (But with Skype/Googletalk/Phone these units are great). The Jabra is usable with TS, but your friends will prefer you use the wired headset. The Plantronics is basically unusable with Teamspeak because the bad quality of the Plantronics speaker, coupled with the lackluster audio reproduction of TS, makes it difficult to understand your friends when using TS with the Plantronics. With the Jabra you can still hear clearly on TS, even if your own voice is somewhat degraded.
All in all, I'm pretty happy with this headset. The Plantronics FEELS like a sturdier, better made unit, and is more ergonomic, but ultimately the audio quality differences overcome that and put the Jabra on top.
