Great Headset connector type RJ9 extremely hard to find
I needed this to start a training class for a new telecommute job I had just landed. Starting April 5, 2016.
I am disabled and a little hard at hearing. This has excellent noise cancellation attributes and was exactly what I needed as required by my new employer. They work perfectly with the hard line telephone I was required to have to accept the job. This phone which I was also able to obtain from the same seller.
Hours of research to get this quality. I would recommend this to anyone who requires this type of headset.
I can hear very well out of them, but they apply so much pressure to my ears that it causes me pain. 1.5 hours is as long as I can stand having them on my head.
