Stable Signal & Long Transmission Range for All Scenarios

Say goodbye to spotty signals!

It covers up to 100-150 meters (328-492 ft) in open areas—perfect for large museums, factory floors, campus tours, or outdoor historical sites. Boasting an S/N Ratio of ≥80dB and effective noise reduction, it filters out background clutter (like exhibition crowds, factory machinery, or busy church halls), leaving only crisp, clear sound. Every listener hears you loud and clear, no matter the environment.

One-Click Operation & Hands-Free Comfort

Setup takes seconds—no tech expertise required! Press one button on the transmitter to pair all receivers (no tedious one-on-one settings), and another button to turn off all connected receivers at once—save precious time after events. The 70g (0.15lb) transmitter comes with a lanyard for easy neck-wearing, while the 18g (0.04lb) ultra-light receiver features an ear-hook design—hygienic, convenient, and barely noticeable even after 8+ hours of use. Plus, the transmitter has a mute function: press it when you need a private chat, and the audience won’t hear a thing. Ideal for long tours, all-day classes, or extended court interpreting.

Powerful Performance & Flexible Usage

Unique feature: 2 transmitters can work simultaneously on the same channel—perfect for two guides/interpreters taking turns to reduce fatigue, or one speaker with background music (via AUX input). The dual sound source interface includes a dedicated mic port (8 mics included: lapel & headset) and a standard 3.5mm AUX port for connecting smartphones, MP3s, or church sound systems. With 9999 selectable channels, hundreds of groups can use the system in the same space without cross-talk—ideal for large conferences or multi-group museum tours. Best of all, one transmitter pairs with unlimited receivers, fitting small meetings or large-scale events (hundreds of attendees).
