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.

Minimizes distortion and external noise for clearer, more natural, and more immersive listening.

Supports microphone input and external audio transmission for flexible use.

Supports both Type-C charging and contact charging with 32-slot or 60-slot charging solutions.

The system supports a transmission range of up to 200m / 656ft, allowing guides and participants to maintain clear communication even when the group is spread out. It is especially practical for outdoor tours, factory visits, school groups, and large-scale guided activities.

The built-in rechargeable lithium battery supports up to 40 hours of operation for the receiver and up to 8 hours for the transmitter, helping ensure stable all-day performance without frequent charging.

Quickly silence the receiver when private discussion or a short communication pause is needed.

One-click pair and stored channel memory help save time during setup and repeated use.

Turn off multiple receivers at once to improve collection efficiency after tours, training, or events.

The original C-shaped headphones have been upgraded to D-shaped headphones for a more secure fit and improved sound performance. The updated design helps the earphone stay in place more comfortably during movement.
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.
Automatic Power-off
The receiver automatically shuts down after 20 minutes of no signal, preventing users from forgetting to turn it off and improving operational efficiency.
Comfortable and Portable
