A new architecture for professional team communication
Powered by SYNCO’s self-developed Mesh Talk™ engine, MasterFree 3.0 removes the master device entirely and builds communication on a fully decentralized, self-organizing, and self-healing mesh network.
Designed for teams that demand real-time response, high reliability, and seamless scalability - without complexity or single points of failure.
Key Highlights:
- True master-free mesh architecture
- Ultra-low latency down to 0.045s
- Automatic self-healing and routing
- Scales from small teams to 40 users without performance loss

▎Why Master‑Free Matters?
Traditional intercom systems rely on a master headset to route all audio. This design creates unavoidable risks:
- A single point of failure can shut down the entire system
- Latency increases as team size grows
- Complex setup and recovery slow teams down
MasterFree 3.0 removes the master completely. There is no central control device, no hierarchy, and no dependency.
Master-Based vs. Master-Free Communication: Why Traditional Intercom Systems Fall Short
| Traditional Master-Based Systems | MasterFree 3.0 - Mesh Talk™ |
|---|---|
| Requires a dedicated master device | No master device at all |
| Single point of failure | Zero single point of failure |
| All audio routed through the master | Direct device-to-device communication |
| Latency increases as users join | Ultra-low latency stays consistent |
| Manual setup and recovery required | Automatic self-organizing & self-healing |
| Limited scalability | Seamlessly scales up to 40 users |
▎How MasterFree 3.0 Works?
✓ One Minute to Understand Mesh Talk™
Mesh Talk™ is a master‑free communication architecture designed at the system level — not controlled by any single device.
1. Network Formation
When devices power on, they automatically discover nearby nodes and establish a mesh network. No manual pairing, no role assignment, and no master selection are required.
2. Equal‑Node Operation
Each headset functions as an equal intelligent node. Audio data is exchanged directly between devices, eliminating centralized routing and dependency.
3. Real‑Time Adaptive Routing
The system continuously evaluates link quality and dynamically selects the optimal transmission path to maintain low latency and stable communication.
4. Built‑In Self‑Healing
If a node disconnects, moves, or powers off, the network automatically reconfigures itself in real time, rerouting audio through available nodes without system interruption.
5. Predictable Scaling
As additional users join, the mesh expands horizontally. Latency and communication stability remain consistent, without performance trade‑offs.
Result:
A resilient, low‑latency, and fully decentralized communication system — engineered for professional, real‑time team collaboration.
✓ Key Advantages
Ultra Low Latency Communication
Mesh Talk™ uses a single-layer mesh network, eliminating master based audio routing.
- End to end latency as low as 0.045s
- 77% latency reduction compared to first generation systems
- Full duplex communication for natural, real time conversation
The result is communication that feels instant - even in fast moving, high pressure environments.
Scalable Without Compromise
MasterFree 3.0 is designed to grow with your team.
- Up to 8 users in native mesh mode
- Expandable to 40 users with XStation
- No latency increase as the system scales
- Communication range up to 500m
Large teams operate with the same responsiveness and stability as small ones.
Zero Single Point of Failure
Because there is no master device:
- No headset controls the system
- No single failure can break communication
- The network automatically adapts in real time
This architecture delivers mission‑level reliability for professional operations.
Software‑defined Control
Through the SYNCO AUDIO App, MasterFree 3.0 adds intelligent system control without additional hardware.
- Device pairing and network management
- Group creation and private channels
- Permission and role configuration
- Firmware updates and future feature expansion
Advanced control - without the cost or complexity of hub‑based systems.
