With a medium-sized Bluetooth speaker, you get a Bluetooth speaker with a powerful sound. These speakers have different designs. There are speakers with designs that are an addition to your interior. Think of wooden materials or built-in mood lighting. There are also models that are made for on the go, because they're dust and water-resistant. The JBL Charge 5 and Ultimate Ears MEGABOOM 3 have an IP67 certification and a design that can take a hit, for example.
