The J-B6 tour guide system is a one-to-many wireless audio guide setup built for group tours, factory visits, museum walkthroughs, conferences, and training sessions. Its transmitter broadcasts over Bluetooth 5.0 to open-ear receivers that sit outside the ear canal, so guides and listeners stay aware of their surroundings while moving through noisy or crowded environments.
Key Features
- Open-ear, not-in-ear design — the J-B6 receiver uses air-conduction sound delivery that keeps ear canals open, reducing fatigue on long tours.
- Long-range coverage — receivers stay connected up to 300 meters from the transmitter in open, unobstructed conditions.
- All-day battery life — receivers run up to 15 hours per charge, with a full recharge in about 2 hours via magnetic charging contacts.
- Lightweight and comfortable — each receiver weighs just 18g for extended wear.
- Multi-source transmitter — switches between Bluetooth, TF card, USB, radio (FM), and line-in audio input at the press of a button.
- Built-in recording — record from the microphone or a connected wired mic directly to USB/TF card, with playback and delete controls.
- Infrared remote support — the transmitter can be operated from up to 10 meters away.
- 9999+ channels with a color LCD display for quick status checks in the field.
How It Works
Power on the J-B6 transmitter and receiver with a 3-second long press on each. The receiver defaults to receiver/monitor mode on startup. Double-clicking the receiver's power button enters pairing mode — the indicator light flashes blue during pairing and turns solid blue once connected (the transmitter's one-touch pairing function must be enabled).
In receiver/monitor mode, a single press on the volume buttons adjusts output across 5 levels. In Bluetooth mode, volume follows the connected phone's volume level. Pressing both volume buttons together quickly cycles the receiver between Bluetooth mode, receiver mode, and monitor mode.
Application Scenarios
The J-B6 tour guide system fits a wide range of group-listening scenarios, including:
- Museum and heritage site guided tours
- Factory and facility walkthroughs
- Conference and simultaneous interpretation support
- Training sessions and classroom instruction
- Outdoor group tours and site inspections

FAQ
Q: Are the receivers in-ear or over-ear?
A: Neither — the receivers use an open-ear hook design with air conduction, so nothing sits inside the ear canal.
Q: How many receivers can connect to one transmitter?
A: The transmitter supports 9999+ channels, making it suitable for one-to-many group tour setups.
Q: Can the transmitter play audio without a phone?
A: Yes — the transmitter also accepts USB drives, TF cards, FM radio, and a wired line-in/microphone input, in addition to Bluetooth.
Q: How long does the system run on a full charge?
A: The receiver lasts up to 15 hours per charge (2-hour charge time), and the transmitter runs approximately 8 hours per charge.
