1. Introduction
The vapeonly J3 Bone Conduction Mini Speaker, also known as the Humbird speaker, is a compact and versatile audio device. It utilizes bone conduction technology to transform almost any hollow surface into a speaker, offering a unique and amplified sound experience. This manual provides essential information for setting up, operating, maintaining, and troubleshooting your speaker.

What is Bone Conduction Technology?
Bone conduction technology transmits sound vibrations directly to the bones of your head, bypassing the eardrum. In the context of this speaker, it means the device vibrates against a surface, causing that surface to resonate and produce sound. This allows for a customizable audio experience, as different surfaces will produce varying sound qualities and volumes.

- Now, connect your device to the master speaker via Bluetooth as described in section 4.3.
5. Operating Instructions
5.1 Placing the Speaker on Surfaces
The unique feature of this speaker is its ability to use various surfaces to amplify sound. Experiment with different hollow objects for diverse audio experiences. Use the provided viscose stickers to securely attach the speaker to a surface.

Figure 4: Examples of different surfaces for sound amplification.
- Recommended Surfaces: Wood, cardboard boxes, plastic containers, glass, metal, and even dashboards.
- Sound Variation: Each surface will produce a distinct sound profile. For example, a cardboard box might offer a warmer, bass-heavy sound, while a glass surface might provide clearer highs.
- Attachment: Peel off the protective film from the viscose on the bottom of the speaker and firmly press it onto your chosen surface.
5.2 Basic Functions
- Play/Pause: Short press the Function Key (2) to play or pause music.
- Next Track: Double-click the Function Key (2) for the next song.

6. Maintenance
To ensure the longevity and optimal performance of your speaker:
- Cleaning: Wipe the speaker with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Water Resistance: This speaker is NOT waterproof. Avoid exposure to water or excessive moisture.
- Storage: Store the speaker in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting
If you encounter any issues with your speaker, please refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Speaker does not power on. | Low battery. | Charge the speaker fully. |
| No sound or low volume. | Not properly placed on a surface; device volume too low; speaker volume too low. | Ensure speaker is firmly attached to a hollow surface. Increase volume on both the connected device and the speaker. |
| Bluetooth pairing fails. | Speaker not in pairing mode; device Bluetooth off; too far from device. | Ensure speaker is flashing blue (pairing mode). Turn device Bluetooth off/on. Move speaker closer to device (within 10 meters). |
| TWS pairing fails. | Speakers already connected to another device; incorrect pairing steps. | Disconnect speakers from any other devices. Follow TWS pairing steps carefully (Section 4.4). |
