Excellent headset


I'm not sure what the other reviewer is talking about. This headset has been excellent for us. It's very comfortable too


Consumer review by:

Horrible Sound Quality




This headset has by far, the WORST sound I've EVER heard from ANYTHING. Even it's intended purpose of voice, it just sounds TERRIBLE. We use it in our office, and it is just disgusting, I can't figure out how it's possible to make a headset that sounds...


Consumer review by:

More comfortable than an in the ear mode


If you need two hands to type, then this headset beats the in the ear type.

Clear Reception,Durable

Consumer review by:

Excellent Product


These are mostly used for a "Contact Center" environment. We use these in conjunction with the Nortel Networks NTDU92 phones.

Excellent clarity, the mic picks of every word as if you were right infront of the customer!

This is partially a con, the mic is so sensitive that is picks up every keystroke and the conversations from others talking in the same room.

Plantronics HW251N SupraPlus Wideband Noise-canceling Monaural Headset


Good Product, I like the audio, the way they fit and the way they plug into the computer. They look snazzy and do the job quite well. They are worth a try for anyone. Good Product, Good Seller, Good Service, and a good money investment. Try them out!

Works with my Shoretel 230

Plantronics HW251N SupraPlus Wideband Noise-canceling Monaural Headset


Works fine. I use it at work for conference calls. It's a little expensive, but I am able to hear better and everyone hears me when I speak fine. Took me a while to get used to it, but beats holding the telephone for calls 30 minutes or longer.
