Three beamforming microphones isolate voices from room reverb and ambient noise for a rich, dynamic audio experience. This array focuses on the speaker while suppressing background distractions in open spaces. The technology enables crystal-clear audio on both ends of the call without manual adjustment. It is the decisive feature for buyers who need reliable voice pickup in variable acoustic environments.

Questions about this item

How do I set up the EXPAND 40 for a meeting and what step do people often miss?

Connect via Bluetooth or the USB-C cable for plug-and-play use; the step often missed is selecting the EXPAND 40 as both the microphone and speaker in your meeting platform's audio settings.

What part of the EXPAND 40 will need replacement after extended use?

The built-in rechargeable battery will eventually lose capacity after many charge cycles, reducing the available talk time from the rated 18 hours.

How many people can the EXPAND 40 support clearly before audio quality drops in a sustained meeting?

The three beamforming microphones are optimized for up to 8 participants; beyond that, voice isolation and pickup clarity decrease noticeably.
