Can you hear me now
I can hear all calls more clearly and it’s very convenient. I should’ve bought them a long time ago

Well worth the money spent!
The headset is a very nice headset and very much improves my daily workflow. It's not perfect and it's definitely not a high-end unit, but it does the job and does so admirably. I have not the cushion off the headset two or three times, and I know that eventually it will tear due to the construction, however, a little more caution and it'll certainly last a while. Audio quality seems top notch from what I can tell. The microphone switch does have a little play in it, and I have on two occasions noticed that I'm muted when I didn't realize I was muted. Otherwise, it has been an awesome purchase!I have dropped a star after a couple of weeks not due to the product, which is really good, but rather, I keep getting emails asking for a review which I already gave it a 4 start!

Easiest headset to hook up
I plugged them in my work home and was ready to go. The head adjustment was easy to adjust, I did not have a problem with listening from it either.
