Digital tour guide audio equipment offer significant advantages in terms of interference resistance and noise reduction. Through digital modulation, sound quality is enhanced, resulting in a clearer and more pleasant audio experience. Furthermore, encoding technology minimizes noise or echoes caused by interference, while improving transmission security and stability. Even in noisy tourist attractions or manufacturing plants, listeners can clearly hear the guide's voice, unaffected by external disturbances.

Minimizing distortion and external noise for an immersive and clear listening experience.

In addition to supporting MIC input, it can also transmit external audio via Bluetooth or AUX interface.

Supports dual charging options: Type-C cable and contact-based charging with 32/60-slot case for efficient multi-device powering.


TThe digital wireless audio guide system has a range of up to 200m/656ft. This allows the guide/team leader and the participants to maintain clear, uninterrupted communication even at considerable distances from each other. This is particularly useful in large groups or outdoor excursions where participants may be scattered.


Equipped with a built-in rechargeable lithium battery, the receiver can operate continuously for up to 40 hours, while the transmitter functions for 8 hours, without frequent recharging. Enabling all-day touring without frequent charging.

Simply press the mute button on the transmitter to silence the receiver, allowing for private conversations or temporary audio pauses.

The one-click automatic channel synchronization eliminates individual pairing; the system remembers previously paired channels for easy use.

For events with multiple receivers, the one-click shutdown function saves time by forcing all receivers to turn off simultaneously.


The transmitter microphone offers 4 levels of gain adjustment, allowing team leader to fine-tune the microphone gain based on ambient noise levels and visitor feedback. The receiver volume offers 10 levels of adjustment, catering to different hearing needs and ensuring a comfortable listening experience for everyone.
The receiver automatically shuts down after 20 minutes of no signal, preventing users from forgetting to turn it off and improving operational efficiency.
The chest-hook style is compact and portable, featuring a universal ear hook for both ears for flexibility and comfort, and replaceable foam covers ensure hygiene.
The transmitter supports charging while in use, allowing for normal operation even with low battery.
It supports up to 50 channels, ensuring that audio transmission will not be interfered with even if multiple teams are working at the same time in the same area.
