Pair of conference microphones
Two HP Poly Trio C60 expansion microphones connect to a compatible conference phone to extend voice pickup for larger meeting rooms. The 3.5 mm jack provides a simple wired link without additional drivers or configuration. Each unit includes a built-in stand for stable tabletop placement. This pack suits teams that need broader coverage in huddle spaces or boardrooms.
Wired connection with no external power
The 3.5 mm jack draws power directly from the host device, so no separate power supply or batteries are required. Passive operation keeps the setup silent and free of fan noise or heat output. Cabling remains lightweight and easy to route around furniture. The design avoids any active electronics that could introduce hum or interference.
Dual stands for flexible positioning
Two integrated stands let participants place each microphone where voices are clearest, whether at opposite ends of a table or near a presenter. Black finish matches typical conference-room aesthetics without drawing attention. The pack-of-two quantity supports stereo-style pickup or wider mono coverage depending on the host system. No additional mounting hardware or software licences are included.

Questions about this item
How do I connect the 3.5 mm jack on each expansion microphone to the Trio C60, and what step is often missed?
Plug the 3.5 mm jack of each microphone into the dedicated expansion ports on the Trio C60 base; the step often missed is seating both plugs fully until they click, otherwise the second mic stays inactive.
What part of these microphones is most likely to need replacement after extended conference use?
The 3.5 mm plug and cable are the wear points; repeated insertion and cable flexing at the connector can degrade the contact over time.
How far from the base can each microphone pick up voices before audio quality drops in a long meeting?
The Trio C60 expansion microphones extend pickup to roughly 60 cm from each unit; beyond that distance, voice clarity and echo rejection decrease noticeably.
