Eartec ULSR HD UltraLITE Single Remote Headset, Single or Multipack Options

The EARTEC ULSR HD UltraLITE Single Remote Headset delivers hands-free, full-duplex communication via secure DECT 6.0 wireless technology. Designed for professional settings like broadcast, event production, and team coordination, it supports real-time voice exchange within a 400-meter open-space range. This HD version is not compatible with Classic UltraLITE systems sold before May 2018.

The all-in-one design eliminates the need for wires or belt-worn radios. Its adjustable microphone boom rotates 270° to allow left or right ear use. A lithium polymer battery provides up to 6 hours of continuous operation per charge, with recharge taking just 3 hours. Multiple configuration options allow teams of 2 to 4 users to communicate simultaneously using a Master and up to 3 Remote units.

This model is available in several headset kit configurations to suit different team sizes.
