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.

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.

I use this speakerphone several times a week for conference calls at work. The sound quality is great, it pairs with Bluetooth without any issues immediately when turned on. The case is great plus for storing it and traveling. Highly Recommended !

Portable and have great distance. We use this product for many of our clients. The clients often need speakerphone that can pick up a room meeting. Love the idea of bluetooth allow us to move the speakerphone closer to presenter or moderator and client sit far and observe.

Easy To Set Up

Battery Status Not Easy

Have ordered a few of these now and they work great!

on use so far the device has produced clear sound and the mic picks up a decent sized room without any problems. installation is just plugging in the USB and away it went.

I was already working on this review of the Plantronics Calisto 620 portable wireless UC speakerphone when I went to Florida for the day and found myself using it. That experience alone was enough for me to give this Bluetooth speakerphone a rave review.

Easy to set up and use; Good audio quality; Includes Bluetooth adapter and carrying case; Spokes software is a free download; Excellent performance for people who work on the go

You will have to decide between this and the Jabra Speak 510; Keep an eye out for our head-to-head between the two products

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.
