The SPK815 karaoke speaker with microphone is perfect as a professional solution for parties both during evenings spent with friends at home and summer nights on the beach or terrace. A compact casing ensures maximum durability in tough operating conditions, and the Bluetooth function allows you to connect the karaoke speaker with a microphone to external devices such as a computer, phone, or tablet. Communication is also facilitated by the built-in USB port, which allows direct music playback from a portable drive, and an AUX jack with an included cable. The 15 W Bluetooth speaker with a microphone and a frequency range of 20-18,000 Hz also features a built-in FM radio, so you can listen to your favorite stations wherever you are. A modern battery provides up to 3 hours of uninterrupted playback on a single charge - one of the best performances you can find in this category of devices.
