Review on Enhanced 900 MHz Wireless Office Headset System - Plantronics CS50 (Discontinued by Manufacturer) by Kevin Hole

Our entire sales team use the CS50 and have been using this model since 2007. During this time only 1-2 people left us. These are 900MHz models, which are good and bad. Okay, so you get good range and it doesn't struggle with other devices in the higher range of 2.4 gigabytes and up. Too bad the audio quality isn't crystal clear, but with VoIP, SIP and cellular somewhere down the chain, the audio quality is bound to get worse. A NOTICE. They are out of production. If you need more, buy them now. Bought bunch.
