Have you ever wanted to play your Bandai WonderSwan using headphones instead of the built-in speaker? The WonderBeat 9480 will allow you to do that!
With hot-swap capability, you can plug/unplug your headphones or the adapter itself which will turn off/on your internal speaker.
These now come pre-installed inside of a 3D printed shell.
Note that the adapter you receive may not look exactly the same as what is pictured, as we may edit the design of the shell or circuitboard.
