This remains a big, chunky and fairly heavy speaker. But It is also curvier-looking than predecessors and durable with an IP67 ranking. An optional spare battery extends its roughly 12-hour play time. The IPX4-rated speaker has jacks for any guitar and microphone, so it’s good for karaoke and busking. https://www.bluetoothspeaker.top/professional-wireless-bass-portable-dj-party-smart-gaming-bluetooth-speaker/
