Two expansion microphones for CC3500e

These two extension microphones connect directly to the Logitech CC3500e speakerphone to widen voice pickup for larger meetings. They are designed for conference rooms where up to 20 participants sit around a single table. Each unit adds an omnidirectional, noise-cancelling mono microphone that requires no separate driver installation.

Passive USB-powered operation

The microphones draw power and transmit audio through the existing CC3500e connection, so no extra power adapter or wall outlet is needed. Plug-and-play detection means the speakerphone configures gain and mute status automatically the moment they are attached. LED indicators on each unit show mute state, active call and Bluetooth pairing without adding audible fan noise or measurable heat.

Mute button and status LEDs per unit

Every microphone includes a dedicated mute switch and its own LED ring, letting any participant silence their side of the table instantly. The bundle supplies two identical modules so coverage can be placed at opposite ends of a long room. Buyers needing wireless tabletop microphones or a standalone speakerphone will not find those functions here.

Questions about this item

How do I connect the extension microphones to the CC3500e and what step is often missed?

Plug each microphone into the CC3500e speakerphone for automatic detection; the step often missed is waiting for the LED indicators to confirm mute, call, and Bluetooth pairing status before starting the meeting.

What maintenance or replacement will the two extension microphones need over time?

The microphones have no user-serviceable parts; keep the 83 mm by 83 mm by 21 mm units free of dust and replace only if the mute button or LED indicators fail.

What limit appears first when the microphones are used continuously in a 20-person room?

The omnidirectional pickup is designed for up to 20 participants; beyond that distance the noise-canceling mono wideband microphones lose clarity and the LED status indicators become the primary feedback.
