Xuan June’s hearing aids have kept her company for pretty much her entire life. They go with her to school, tag along for a ride while she skateboards and sit snugly while she draws and dreams up goth-cute fashion designs.

In this episode, Xuan June is getting fitted for a new pair of hearing aids — and she’s invited Molly to come with her! Together they learn all about how these cool superpowered devices work. Plus, we find out how sound travels and get a chance to guess TWO mystery sounds.
