SYNCO Xtalk Master Wireless Two-Way Communication Headsets, Master-Free Connection, App Control, Team Expansion, Smart Group Management, 45ms Low Latency. Powered by SYNCO’s world-first* (as of 1 October, 2025) self-developed Mesh Talk MasterFree 3.0 Technology, Xtalk Master wireless two-way communication headsets completely remove the traditional master–slave structure. Every headset operates as an independent node, instantly forming a fully adaptive mesh network the moment it powers on. As team members move, disconnect, or rejoin, the network automatically reorganizes and self-heals, keeping communication seamless, stable, and uninterrupted, with no setup required.
