Start an Audio Conference in Seconds

Set up the AS311 speakerphone quickly and easily with USB plug and play connectivity.

The AS311’s single-corded design ensures a smooth setup and stable connection for conference calls without having to worry about running out of power or technical difficulties.

Flexible, Hands-Free Conferencing

With the AS311, you won’t be tied to a device’s microphone but can comfortably walk around the room while still being heard clearly.

You no longer have to be stuck in your chair for meetings.

Deliver Crystal Clear Communications Wherever You Are

With AI-powered technology, the AS311 speakerphone suppresses distracting background noises, such as your baby crying, your dog barking, household appliances, and more, to deliver your uninterrupted, clear voice to meeting participants.

It’s suitable for various conferencing environments, no matter if you are in the office, at home, or outside.

Turn on noise reduction with a click of a button.

One Tap to Mute or Unmute

With a single tap, you can mute or unmute yourself intuitively to avoid any disturbance. The AS311 comes with ergonomically designed touch buttons that give you control over your calls easily.

Participate in Calls from Any Angle

The AS311’s omnidirectional microphone and speaker will pick up and broadcast sharp sound in all directions (up to 9.8 ft./3 m), turning any environment into a meeting space.
