3.5 mm TRS conference microphone 5 pack

This set provides five omnidirectional boundary microphones for group calls on PCs and recorders with a 3.5 mm TRS stereo powered jack. Each unit captures sound in a 360 degree pattern so multiple participants are recorded at once. The microphones connect via a standard TRS plug and are not compatible with TRRS 4 pole sockets without an adapter. They suit offices, classrooms and huddle rooms that need simple plug and play audio capture.

Daisy chain expansion for larger groups

Additional microphones can be linked in series using the daisy chain option to extend coverage across bigger tables. The wide frequency response maintains clarity and intelligibility when several people speak simultaneously. Each microphone has an eight foot cord giving flexible placement without signal degradation over the chain. The condenser design delivers consistent output during long conferencing sessions without needing external power beyond the jack.

Zippered cases and TRS only connectivity

Five zippered carrying cases keep the microphones and cables organised for transport between meeting spaces. Installation is limited to plugging the TRS connector into a compatible powered jack; no drivers or software are required. The only common issue is attempting to use the microphones with TRRS 4 pole ports found on many laptops and mobile devices, which will not work without a separate adapter. Ensure the host device provides a TRS stereo powered input before purchase.

Questions about this item

Does the 3.5 mm TRS plug draw any power or generate heat during all-day use?

The microphone is passive and draws no power from the 3.5 mm TRS jack, so it produces no measurable heat even during continuous operation.

What jack must my computer already have for these microphones to work?

Each unit needs a 3.5 mm TRS stereo powered jack; a 3.5 mm TRRS four-pole jack will not work unless you add a TRS-to-TRRS adapter.

Can I keep using my older TRRS headset jack while adding these mics?

The microphones require a TRS stereo jack, so they cannot plug directly into a legacy TRRS headset port without a separate adapter.
