EARTEC ULSR-HD Ultralite HD Remote Headset - Full Duplex Range

In this review the EARTEC ULSR-HD Ultralite HD Remote headset is assessed as a practical extension for existing UltraLite HD systems; it is aimed at teams that need reliable, full duplex wireless talk in noisy environments. The single biggest reason to buy is compatibility with the HD UltraLite ecosystem plus the combination of a noise-cancelling microphone and up to 1,000 ft line-of-sight range, which together deliver clear, hands-free communication for production crews, boat operators, or construction teams.

Key Features

• Compatibility: Designed specifically for the Ultralite HD line, it ensures seamless integration with HD Main or HUB systems when replacing or adding remotes.
• Expandability: Systems with a Main headset support up to four Remote units and HUB systems support up to eight, making scaling straightforward for larger crews.
• Wireless Range: A quoted line-of-sight range of up to 1,000 ft gives crews the freedom to operate across large outdoor or open indoor spaces without losing communication.
• Battery Life: Rechargeable battery provides up to six hours of talk time on a single charge, which covers most event or shift-length uses without frequent swaps.
• Noise-Cancelling Microphone: The mic reduces background noise and automatically mutes when pivoted up, improving clarity in loud work environments.
• Wear Flexibility: Pivoting microphone lets the user wear the headset on either left or right side for comfort and convenience.

Who It's For

This headset is best for video and stage production crews, drone operators, boat pilots, and construction teams who already own an Ultralite HD Main or HUB system and need additional Remote units with dependable range and clear audio. The full duplex design helps teams coordinate without talk/receive delays common to simplex systems.

Those who should look elsewhere are users of Classic Ultralite models (this unit is not compatible) and buyers who need longer than six hours of continuous operation without access to charging or spare batteries; in those cases consider a different model with extended battery options.

Pros & Cons

Pros
