Plantronics SupraPlus CS361N Noise-Canceling Wireless Headset DECT
Customer Reviews
I purchased this CS361N headset to work with a Polycom SoundPoint Pro SE-225 desk telephone (not VOIP). I wanted a binaural design so that I would be less distracted by other noises around me while engaged in a conversation or even just listening.
Set-up is Easy: the Polycom corded handset (curly cable) connects to the base of the Plantronics unit and an RJ-11 cable goes from the Plantronics out jack to the side of the Polycom phone. After making a few minor adjustments to earphone volume and speaker sensitivity (defaults were adequate), the headset worked extremely well.
Quality ; Comfort: audio quality is outstanding and people report that my voice sounds natural and clear on the receiving end. The headset is relatively light and the cushions sit gently on the ear (vs. over). I prefer the padded (leatherette?) cushions that came stock vs. the optional foam cups. The mouthpiece is adjustable and easily slides up/down when I want to move it away from my lips. I can wear these phones for hours at a time comfortably.
Operation: I am only occasionally involved in long teleconferences, so I typically do not wear the headset all day long. I have it configured so that, when I want to make a call, I put on the headset, then uncradle the Polycom handset and set it on the desk (opens line). From that point, I just dial a phone number. I am not using an optional auto-handset-lifter (don't need it); so, when a call is over, I merely hang up the Polycom handset, press an end call button on the left earpiece, and cradle the Plantronics in its recharger.
Recharger: I cannot remember how long a full charge lasts, but I think it might be 8-10 hours or so of continuous use. I have never left it off the recharger long enough to run out of juice and cannot imagine such a scenario occuring unless it happens accidentally. When the headset is properly seated/mounted on the recharger, a yellow light comes on and either blinks (recharging) or is solid (fully charged). When the headset is off the recharger, a red LED lights up. A green LED indicator on the top of the unit indicates "In a Call" (solid) or "Mute" (blinking). Couldn't be much easier than that!
Range: the range on this unit is quite extensive. While on a call recently, I walked outside to my mailbox (end of driveway) and was STILL connected. On many long conf calls, I meander all around my first floor (e.g. kitchen) with no static or disruptions of any kind.
Static: occasionally, I get some static on a call, but I haven't been able to determine the root cause. In some cases, it might be coming from the distant connection (e.g. VOIP!). Per the Plantronics instructions, I moved the recharger base unit at least 6" away from the Polycom. The incidents of static dropped considerably after that change. Most calls are pure and clean unless affected by my Blackberry (GPRS) which does cause electronic interference when it periodically syncs with the mother ship. The simple solution there is to move it further away from the Polycom.
I have only one gripe: while on mute (button is on left earpiece), the Plantronics unit beeps in my ear every 10 seconds or so which becomes quite annoying when I am on a long conference call listening to the dialogue. The recharger unit also blinks (LED) to indicate that the call is on mute, so I don't know why the beeping cannot be turned off optionally. It would be easier to slide the mouthpiece up to remind myself that I am on mute, so I don't need to be constantly pestered with that incessant beeping. I haven't found a way to disable it, so I am going to raise that concern with Plantronics.
Overall: excellent product and works extremly well. I am very satisfied with this purchase, especially in combination with the Polycom SoundPro SE-225.

I have been using the Plantronic's S11 for about 5 years now. It is wired but worked really well. The sound was perfect and I never had a complaint. Wanting to go wireless, I read reviews and felt the CS55 would fit my needs. I ordered it on Amazon and installed immediately upon receipt. My initial impressions were "so-so". It was a nice upgrade to be wireless but the headset did not sit firmly against my ear (using the over-the-head attachment), the sound was a bit "airy" - hollow-sounding. It definitely was not as good as my S11. I also heard my own breath often during calls. Whether it was from a sigh or just during the normal air release from talking...it was very annoying. I fiddled around with the controls for a long time and made about 35 calls to my wife to test (she was annoyed). I never got it correct and called Plantronics. They walked me through all the controls but still could not eliminate the 'wind' sound. I never once had the wind sound from my S11. So I returned the CS55.
I then ordered the CS361N. I talk frequently to someone else with this headset and his voice is always clear. He raved about it. After plugging it in, I made my first call - to my wife again. No adjustments...and it was perfect! I could hear VERY clearly and the ear phones sit securely on my ears. I could bend over and move around and it did not feel like it was going to fall. My CS55 fell off several times during light movement behind my desk.
I also know someone that recently bought the Jabra GN9125 and he sounds "airy" - or hollow.
I wasn't sure I would like the stereo sound of having two ear pieces but it really is nice. My office is quiet so distractions are not an issue but it really forces me to focus. I'm sure I would also be happy with the Monoural CS361N.
Hope this helps!
