Operating Instructions

Bone Conduction Technology

These headphones utilize true bone conduction technology, transmitting sound through vibrations directly to your inner ear bones. This innovative design allows your ear canal to remain open, ensuring you can hear your audio while staying aware of ambient sounds and your surroundings. This is particularly beneficial for outdoor activities where situational awareness is crucial for safety.

Wearing the Headphones

The LibreFit Aurora B17 headphones feature an open-ear design with ear hooks for a secure and comfortable fit. Simply slip the ear hook over the top of your ear, ensuring the main speaker unit rests comfortably near your ear canal without entering it. The design is ultra-lightweight at under 0.28 oz (single earbud), providing all-day comfort without pressure.

Aurora Mode (RGB Light)

The Aurora Mode activates dynamic RGB lights on the headphones, enhancing your visibility during night activities such as running or cycling. This feature adds an extra layer of safety in low-light conditions.

To activate/deactivate Aurora Mode: Refer to the quick guide or full user manual for specific button press instructions.

Note: When Aurora Mode is active, the earphone playback time is approximately 3 hours.
