Product Details
Microphone Input
The transmitter carries a built-in unidirectional microphone for hands-free wear, and a 3.5mm jack for guides who prefer a lavalier or headset mic instead. Both routes feed into the same noise-cancellation processing before the signal goes out.
Connectivity
The primary link runs on a dedicated 2.4GHz band across 999 channels. Bluetooth can be switched on separately, giving venues a second connection option for existing AV equipment or as a backup.
Wearable Design
The receiver sits over the ear rather than inside it, which holds up better over a multi-hour tour and doesn't require a custom-fit tip. A lanyard hole is built into the housing for venues that prefer a neck-worn setup.Lorem ipsum dolor sit ametli consectetur notted adipisicing elit sed do eiusmod.
Power
Battery life is rated with the screen powered down between checks. Reception stays reliable across the same 50–300m range as the transmitter's output.

Factory & Industrial Tours
Designed for production facilities, manufacturing plants, workshops, and industrial sites where machinery and equipment create background noise.
Outdoor Guided Tours
Suitable for scenic areas, heritage sites, campuses, and other outdoor environments where wind and surrounding activity can affect voice communication.
Conferences & Simultaneous Interpretation
999-channel selection allows several language channels or session tracks to run in the same venue at once without interference.
