Plantronics Calisto 620 Review
The Plantronics Calisto 620 ($149.95 direct) is a combination Bluetooth wireless and PC speakerphone. Essentially, it turns your computer and phone into a call conferencing system for office or home use. It also has a rechargeable battery; combine that with the Calisto 620's light weight, and you also have a system that travels easily for use in hotel rooms or satellite offices. Unfortunately, while callers sound nice and loud through the Calisto 620's speaker, they can easily tell you're on a speakerphone—and not a very good one at that.
Design, USB Receiver, and CompatibilityThe Calisto 620 is made entirely of black plastic. It measures 4.33 by 4.33 by 1.26 inches (HWD) and weighs 7.2 ounces, or slightly more than the average smartphone. On top, oversized plastic buttons handle Mute, Answer/Reject, and Volume adjustments. On the side of the unit below the Plantronics logo is a sliding switch that handles Power and Bluetooth pairing, plus a micro USB port for charging the device...
The Plantronics Calisto 620 wireless speakerphone offers both VoIP and Bluetooth calling in a compact form factor, but sound quality takes a hit and the price is on the high side.
Solid build quality; Compact, given how loud it gets; Tiny USB VoIP receiver stores neatly in a compartment below the unit
Poor voice quality through the microphones; Expensive
