Extended audio pickup range: Increases the GROUP system’s voice pickup coverage up to about 28 feet (8.5 m), making it suitable for larger conference rooms and groups of up to ~20 participants.

Plug-and-play simplicity: Just plug the expansion microphones into the Logitech GROUP speakerphone — they’re automatically recognized and configured with no extra software required.

Superior sound quality: Mono, wideband, noise-canceling microphones help ensure clear, intelligible voice capture even in rooms with ambient noise.

Convenient mute control: Each expansion mic includes a built-in mute button with an LED indicator that shows status (mute on/off, active call, Bluetooth pairing).

Flexible placement: With long cables (around 2.4 m / ~8 ft), the mics can be positioned across a table or room for optimal voice coverage.

Professional design: Sleek, compact units blend into meeting spaces without clutter, ideal for boardrooms and collaboration areas.

Ideal for large and medium rooms: Particularly effective in rooms where the main GROUP speakerphone mic alone doesn’t reach — ensuring everyone is heard clearly.
