The Dolphin Audio LX90 Series Rechargeable Party Speaker comes with a wired microphone, so it can also act as a 90-watt PA speaker, and a big, 7.4-volt, 4,400 mAh Li-Ion Battery, so it can be used as a power bank. Multicolor LED lights ring the ends. It’s also WaveSync enabled so if you buy 2 of these, they can be paired to double the volume when audio is being streamed via Bluetooth. It also has a 3.5 mm aux input so you can play non-Bluetooth devices through its 5 in. woofer and two 3 in. tweeters.
