Sony has created an Extra Bass Bluetooth Speaker they introduced at CES 2018 that looks awesome. Not only is it capable of delivering surround sound from a little speaker, it has neon lights and is fully waterproof. Not just splashproof, but take it-into-the-pool-to-swim-proof. One of the coolest features if the Party Booster feature. You’ll be able to party chain up to 100 units to create a full surround sound feel.
