Audio-Technica AT-CSP1 USB Speakerphone

1-Year Local Warranty.

How people work and live has diversified with the times. The places we work and study are changing as well. To keep pace with these changes, we have developed a simple USB speakerphone.

It’s a handy size that is easy to carry, so you can work or study anywhere. Simply connect the included USB Type-A cable or USB Type-C™ cable to your computer and start talking immediately.

You can comfortably participate during long online meetings and classes, hands-free. During calls, you can easily control the volume and mute the microphone directly on the speakerphone whenever you need to.
