Many Bluetooth speakers can indeed be used for karaoke, especially those designed with party features in mind. Speakers like the JBL PartyBox Encore Essential come with built-in microphone inputs, making them perfect for karaoke nights. For speakers without dedicated mic inputs, you're not out of luck – you can use a Bluetooth karaoke microphone that pairs directly with your phone, allowing you to sing along to your favorite tunes through any Bluetooth speaker. This versatility makes it easy to turn any gathering into an impromptu karaoke party.
