Plantronics Speakerphone – Professional Audio for Every Workspace
We built the Calisto 610 for professionals who need reliable conference audio without the complexity. This USB speakerphone delivers 360-degree voice pickup and echo cancellation in a compact form that fits inside a laptop bag.
Whether you’re leading a team call from a hotel room or joining a client meeting from a shared workspace, the 610 connects to your laptop in seconds with zero driver installation. Our omni-directional microphone captures voices from every seat around a small conference table, while dynamic equalization keeps your words clear even when background noise tries to compete.
The touch-sensitive call controls let you mute, answer, and end calls without hunting through software menus. We designed it for the way you actually work—quick setup, consistent performance, and audio quality that makes you sound like you’re in the room.

Microphone Technology & Voice Clarity

Every Plantronics speakerphone in our lineup uses omni-directional microphone arrays designed to capture voices from any seat around a table. The difference between our entry models and conference-room solutions comes down to microphone count and processing intelligence.
Our portable models like the Calisto 610 use a single omni-directional capsule optimized for individual users and small huddles. When you step up to the Calisto 620, you gain the same 360-degree pickup with added Bluetooth flexibility for multi-device professionals who switch between laptop and smartphone calls throughout the day.
Connectivity & Platform Compatibility

We design our speakerphones to work the moment you plug them in—no driver downloads, no IT support tickets, no setup wizards. USB models enumerate as standard audio devices on Windows, macOS, ChromeOS, and Linux, which means they’re recognized instantly by Zoom, Microsoft Teams, Google Meet, Webex, and every other conferencing platform.
USB vs. Bluetooth Connectivity
USB connections deliver consistent audio quality without the battery anxiety or pairing hassles of wireless-only devices. Our Calisto 610 is USB-only by design—it draws power from your laptop and maintains a stable connection for hour-long calls.
Sizing Your Speakerphone for Room Coverage

Matching speakerphone capability to room size determines whether participants hear clear audio or constantly ask you to repeat yourself. We rate each model by the number of participants it can effectively serve.
Personal & Small Huddle Spaces
The Calisto 610 and 620 are optimized for one to four people sitting within three feet of the device. These are the right choice for home offices, hotel rooms during business travel, and focus rooms where two or three people collaborate on a laptop. Place the speakerphone in the center of your workspace—voice pickup degrades when participants sit more than four feet from the microphone.

What people are saying


Common Questions About Our Speakerphones
Yes. Our speakerphones enumerate as standard USB audio devices compatible with Zoom, Microsoft Teams, Google Meet, Webex, GoToMeeting, Skype, and any platform that supports system audio devices. No special drivers or plugins are required.
Models like the Calisto 620 and 7200 carry official Microsoft Teams certification, which means they include dedicated Teams buttons for one-touch call answer and meeting join. Even without certification, all our models function fully with every major conferencing platform on Windows, Mac, ChromeOS, and Linux systems.
The Calisto 610 and 620 are optimized for one to four participants sitting within three feet of the device. These portable models work best for individual users, small huddles, and focus room calls.
Our Calisto 7200 covers medium conference rooms with six to eight people around a standard rectangular table. For larger spaces, you can daisy-chain two 7200 units to extend microphone coverage across boardroom-sized areas seating up to sixteen participants.
Absolutely. Models with rechargeable batteries like the Calisto 620 support simultaneous charging and use. When connected via USB, the device draws power from your computer to recharge the internal battery while routing audio through the USB connection.
If you’re using Bluetooth mode, you can plug in the magnetic charging cable without interrupting your call. The speakerphone will continue operating wirelessly while the battery charges. Full recharge from empty takes approximately two hours.
USB-only speakerphones like the Calisto 610 connect exclusively to computers via USB cable. They draw power from the USB port, eliminating battery management and ensuring consistent audio quality without wireless interference.
Bluetooth-enabled models like the Calisto 620 and 7200 offer dual connectivity—use USB for desk calls and Bluetooth for smartphone pairing. This flexibility benefits professionals who take calls on multiple devices or need wireless operation in rooms without accessible power. Bluetooth models include rechargeable batteries rated for seven hours of talk time.
Wipe the exterior surfaces with a dry microfiber cloth to remove dust and fingerprints. For the touch control surfaces on models like the Calisto 7200, use isopropyl alcohol wipes to clean oils without damaging the finish.
The microphone and speaker grills use acoustic fabric that should only be cleaned with a dry cloth. Avoid liquid cleaners or compressed air, both of which can force debris into the microphone capsules. For stubborn dirt around the grill edges, use a soft-bristled brush to dislodge particles before wiping.
Models with Bluetooth connectivity pair with iOS and Android smartphones just like wireless headphones. The Calisto 620 and 7200 both support multipoint pairing, letting you maintain connections to a laptop and smartphone simultaneously.
USB-only models like the Calisto 610 require a computer USB port and won’t connect directly to phones. However, when you’re on a phone call routed through your computer—such as a Teams or Zoom call that includes phone participants—the USB speakerphone handles all audio regardless of whether some callers joined via mobile devices.
Yes. Our Bluetooth models support multipoint pairing, which means the speakerphone remembers multiple devices and can maintain active connections to two devices simultaneously. This lets you receive calls on either your laptop or smartphone without manually disconnecting and re-pairing.
When a call comes in on your phone while you’re connected to your laptop, simply answer using the speakerphone controls—the device automatically routes audio from the active call source. To pair additional devices beyond the two active connections, put the speakerphone in pairing mode and connect from your device’s Bluetooth settings.
