Meet Turtle Shell 3.0, the toughest, best looking, best sounding, waterproof wireless speaker that you will ever have. Now in its third edition, this speaker is a whopping 20% louder than its predecessor - which was at least that much louder than the original - and a lot more efficient to boot. It plays louder, for longer, from further away. It even has improved waterproofing, so you can literally take this waterproof Bluetooth speaker into the water with you. With a 3,600mAh built-in power bank and the ability to wirelessly connect multiple speakers, you will be able to keep the party going for hours: 20 hours to be exact because that's how long the speaker will keep playing on a full charge.
