Add the extra pickup range that larger meeting spaces demand. Poly Trio C60 Expansion Microphones are built to extend audio coverage for conference rooms where participants sit farther from the main system, helping remote and in-room attendees hear speech more consistently. For IT teams standardizing on Poly room audio, this accessory supports cleaner table coverage without changing the core collaboration platform. This expansion mic set is a practical fit for executive rooms, huddle spaces that occasionally overflow, and boardrooms where seating changes from meeting to meeting. By placing microphones closer to speakers, you reduce the need for raised voices and improve intelligibility at the far end of the call. That matters in rooms where audio quality directly affects decision speed, meeting length, and participant engagement. Because it is purpose-built for the Trio C60 family, the microphones integrate into an existing Poly room system rather than introducing another endpoint to manage. That makes them a smart add-on for organizations that want better room coverage without replacing the base unit. For procurement teams, the value is straightforward: a targeted accessory that improves the performance of an installed collaboration investment.
