In the realm of audio technology, wireless speakers have revolutionized the way we listen to music, podcasts, and other audio content. Offering the freedom to move around without the constraints of wires, these innovative devices have become an integral part of our homes, workplaces, and even outdoor adventures. But a fundamental question often arises: Do wireless speakers require a power source?
The answer, as with many things in the tech world, is a resounding “It depends.” There are two main categories of wireless speakers, each with its own energy requirements:
