One-way tour guiding (e.g. TG-200, TG-300): the transmitter (guide) sends audio to multiple receivers (listeners)—ideal for museums, factory tours, and scenic walks. Two-way tour guiding (e.g. TG-201, SmartGo): full-duplex two-way talk lets listeners ask questions or interact in the group—ideal for seminars, skills training, and team collaboration.
These systems are optimized for background noise. The latest SmartGo series includes active noise cancellation (ANC) to reduce ambient sound, while TG series models use digital UHF transmission to keep voice clear and stable at distance or in noisy venues.
No. SongXun tour guide systems support multi-channel operation (some models offer hundreds of channels); groups on different channels avoid interference. SmartGo adds always-on auto scanning and smart pairing so you can power on and sync quickly without manual channel setup.
Built-in lithium-polymer batteries provide roughly 13–23 hours of continuous use depending on model (SmartGo receivers up to 23 hours). Charging uses standard USB (Micro-USB or Type-C), with 2/12/35/60/70-slot charging cases or cabinets for large groups. Receivers also auto power off after 20 minutes with no signal to save battery.
