A wireless speaker is a portable audio device that connects to other devices, like smartphones or tablets, without the need for cables. It typically uses technologies such as Bluetooth or Wi-Fi to stream music or audio content. This convenience allows users to enjoy high-quality sound in various settings, whether at home, outdoors, or during gatherings. These speakers come in various sizes and designs, making them suitable for different preferences and environments. Many wireless speakers also feature built-in batteries, enabling them to operate without being plugged into a power source. Some models even include additional features like voice assistants or water resistance for enhanced usability.
