Rated 3.6 out of 5 by 7 reviewers.
Rated 4.0 out of 5.0 by Works like a charm! I bought this and it was easy to install and use. Great product. July 12, 2016
Rated 1.0 out of 5.0 by Bad quality. I received a replacement for my device but it is just as bad. There is a defective plug for the tip of the adapter. I received already three different devices from you and all of them are just as bad. Your devices used to be of excellent quality. March 3, 2016
Rated 5.0 out of 5.0 by Long lasting and essential for Profssionals All my 7 yrs of call center career went with this. There has been time I was hard on the buttons and never gave up. After prolonged used you might find some static while using push buttons. Good investment as there are many PLT headsets that go with or need this June 20, 2015
Rated 5.0 out of 5.0 by Crystal Clear and 100% reliable Crystal Clear and 100% Reliable. I've been using Plantronics headsets since 1966! I wouldn't think of trying a different company's hardware. This is the 4th replacement in 48 years of constant use 40 hours a week, 50 weeks a year. I think 12 years of constant reliability per headset system is an excellent record. September 2, 2014
Rated 5.0 out of 5.0 by Excellent broadband amplifier/processor I listen to many teleconferences and this, coupled with the SHR2083-01 allows me to hear a person speaking from the back of the conference room on the other end. I chose the Vista/M22 (versus the VistaPlus AP15) based on the specification sheets, dealer comments and comments posted elsewhere. I'm frequently on the phone with people who have a higher voice or linguistic heritage of higher vocals. I wanted to make sure I had a broader spectrum amplifier boosting volume into the higher frequencies to help me better understand and support people, especially over faint connections. Overall, this combination of the SHR2083-01 and M22 is outstanding. Regarding the comment on "ringing", I don't experience feedback loops with this pairing, although pre-purchase it was a factor as I was encountering ringing, only very infrequently. I did consider the AP15 to be more feedback loop resistant but wanted the broader audio range the M22 seemed to have. Post purchase, I haven't had any ringing and the problem may have been from another attendee. On the comment about using a lot of batteries, I bought the AC adapter at the same time as the amplifier (it's not included) and it worked fine. The costs of replacement batteries would eventually be more than the AC adapter cost. May 28, 2014
Rated 2.0 out of 5.0 by Echo This should be renamed the Echo Box, or the Battery Hog, the box that needs to have the power adapter accessory to work properly. I just replaced over 300 of these to a direct HIS cord and almost all the phone issues we were having went away. February 4, 2011
Rated 3.0 out of 5.0 by Plastic... The disconnect portion of the cords are plastic I almost returned it the minute I saw that. However I kept it July 16, 2010
