Plantronics Voyager Edge UC & Blackwire C725 Headsets Review


Plantronics Voyager Edge UC and Plantronics Blackwire C725

Plantronics began in 1961 in Santa Cruz, California by two pilots making aviation headsets. Fast forward 50 years and the brand is well known among aviators, NASA astronauts, and 911 operators for making some of the best headsets for voice communications in harsh and heavy use environments. Plantronics (corporate site) has also become well know in the corporate environment for making some of the most advanced headsets for desk phones focused on comfort and superior sound quality. Personally, I have used one version or another of Plantronics headsets in my office for the last 25 years. Like most technologies, the communications market has evolved with new technology like USB and Bluetooth becoming pervasive as the way to connect devices for communications, replacing mini-plugs and RJ45 based headsets. The latest trends of Unified Communications and VoIP have further increased the demand for quality headsets to allow us to connect from anywhere, over any device, through several different applications to communicate. Legit Reviews received two of the most recent products from Plantronics to meet this need in both a wired USB headset, the Plantronics C725, and a Bluetooth v4 wireless headset, the Plantronics Voyager Edge UC.
