Specifications

Non-In-Ear Comfort: Earhook design avoids ear canal oppression, ensuring hygienic and pain-free wearing for long exhibition hours (suitable for 8+ hours of continuous use).
Automatic Binding & Easy Operation: Receivers pair with the transmitter automatically after power-on—no manual channel adjustment, saving time for exhibition preparation.
Strong Anti-Interference: Operates in the 790MHz-830MHz high-frequency band, resisting signal interference from other electronic devices in crowded exhibition venues.
One-to-Many Efficient Guidance: One transmitter connects multiple receivers, enabling a single speaker to serve dozens of visitors simultaneously without sound loss.
Audio Pre-Storage & Playback: Pre-record product introductions, exhibition explanations, or multilingual content; receivers automatically match the channel and play back upon power-on, reducing reliance on on-site interpreters.
Intuitive LCD Display: Transmitter’s full-function screen shows battery level, channel, microphone/MP3 volume, playback mode, and language—easy to monitor and adjust.
Bulk Charging & Storage: Professional charging boxes support fast simultaneous charging of 36/48 devices; aluminum storage boxes with shockproof design simplify transportation and management for large exhibitions.
Wide Coverage & Long Standby: 200-meter communication distance allows visitors to move freely in exhibition halls; 10-hour working time per charge meets the needs of all-day exhibitions.

FAQ

Q1: Can the receiver be worn by people with different ear sizes?
A1: Yes, the earhook is designed with flexibility, fitting most ear shapes and staying stable during movement.
Q2: How to update the pre-recorded audio in the transmitter?
A2: Connect the transmitter to a computer via an audio cable to import or replace audio files; the system supports common audio formats and automatic channel matching.
Q3: What is the maximum number of receivers that can be connected to one transmitter in a crowded exhibition hall?
A3: It is recommended to connect up to 50 receivers for optimal signal stability; more transmitters can be used for larger-scale exhibitions to avoid signal congestion.
Q4: How long does it take to fully charge the 36-device charging box?
A4: The charging box itself does not need charging—it connects to a 220V power supply to charge devices directly. Each receiver/transmitter takes 2.5 hours to fully charge.
Q5: Is the system suitable for outdoor exhibitions?
A5: Yes, the high-frequency band and 200-meter coverage ensure stable transmission in open outdoor environments; the devices are dustproof and suitable for general outdoor use (avoid direct rain).
