This is still a big, chunky and fairly heavy speaker. But it's also curvier-looking than predecessors and durable with an IP67 rating. Playback controls: Because you can control the playback from your Bluetooth source device (generally a phone or tablet), we don’t involve the speaker itself to have playback https://www.bluetoothspeaker.top/outdoor-party-tws-stereo-party-speaker-large-party-bluetooth-speaker/
