Four-User Full Duplex Intercom

This Eartec UltraLITE system provides wireless full duplex communication for four people. One dual-ear master headset and three dual-ear remote headsets are included. All electronics and batteries are built into the ear cups, so no belt pack transceivers are required. It suits teams that need hands-free voice contact while moving around a workspace.

Wireless Range and Battery Limits

The headsets operate on a wireless link that lets users roam without cables, but the effective range depends on walls, interference and battery condition. Each headset carries its own rechargeable battery inside the ear cup, so talk time is finite and charging downtime must be planned. Heavy multipath environments or long distances will reduce audio reliability.

Compatibility and Fit Check

Verify that the dual-ear form factor is comfortable for extended wear and that the noise-cancelling microphone boom can be positioned for each user. Confirm that the charging method supplied matches your available power outlets and that you have space to dock four headsets simultaneously. Ensure the operating frequency band is permitted in your region before deployment.

Questions about this item

Should I choose the master headset or a remote headset for my role?

The system includes one ULDM dual-ear master headset and three ULDR dual-ear remote headsets. The master unit coordinates the full-duplex link, while each remote connects directly to it for hands-free conversation.

What does full duplex mean for daily use of these headsets?

Full duplex lets all four users speak and listen at the same time without pressing a button or waiting for a turn, so conversations flow naturally like a phone call.

How does the belt-pack-free design affect the wireless range?

All electronics and the battery are built into the ear cups, so there is no separate transceiver to carry; the wireless link is engineered to cover typical indoor production spaces without a belt pack.
