Overview Experience sound in a completely new way. This coin-sized gadget is the world's most versatile bone conduction speaker. Instead of using a traditional cone to push air, it uses a vibrating transducer to turn any hollow object into a speaker. Stick it to a coffee box for booming bass, a glass window for crystal clear vocals, or a guitar body for an acoustic vibe. With built-in FM radio and True Wireless Stereo (TWS) capability, it is the ultimate pocket-sized audio companion for travelers and gadget lovers.
Key Features
DIY Sound Experience: The sound quality changes depending on the surface you place it on. Experiment with plastic storage bins, photo frames, helmets, or dashboards to find your unique "instrument."
True Wireless Stereo (TWS): Automatically pair two of these speakers together to create a 2.0 Surround Sound experience. Place them on opposite sides of a room (on suitable surfaces) for immersive stereo audio.
Built-in FM Radio: No phone? No problem. Switch to FM mode to listen to local radio stations. (Tip: Plug in the USB cable to act as an external antenna for clearer reception).
Compact & Premium Build: Crafted from Aviation Aluminum Alloy, it is durable, sleek, and weighs only 35g. Smaller than a golf ball, it disappears into your pocket.
Powerful Output: despite its tiny size (4cm), it can reach volumes up to 115 decibels (comparable to a loud rock concert) when placed on the right resonant surface.

Usage Instructions
Placement is Key: This speaker must be in contact with a surface to work properly. Holding it in the air will result in very low volume.
The Sticky Pad: Peel off the protective film on the bottom silicone pad before placing it on a clean surface.
TWS Pairing: Turn on two speakers simultaneously and wait 3–5 seconds; they will pair with each other automatically before you connect your phone.
⚠️ Charging Warning
Use Standard 5V Chargers Only: Please use a standard USB port (computer/laptop) or a 5V/1A adapter.
Avoid Fast Chargers: Do not use 9V/12V "Fast Chargers" (like those for modern smartphones), as the higher voltage will damage the battery and internal chip.
