This waterproof speaker floats, lasts 24 hours, and costs $69.99 today

A Bluetooth speaker that fills a room without emptying your wallet is hard to find. The Anker Soundcore Boom 2, a rugged, waterproof model that actually floats, is on Woot for $69.99 through July 10th. That's $20 less than Amazon's usual discount and nearly 50% off the $129.99 list price. Nvidia just gave every robotics lab the same 10-point boost

The speaker runs a 50W subwoofer paired with two 15W tweeters, cranking enough volume for a backyard party or a day at the beach. Anker says it lasts up to 24 hours on a single charge, which means you can take it out all day without hunting for an outlet. Its IPX7 rating means it can survive full submersion and even float, thanks to a sealed design. That's a rare feature that makes it a natural fit for poolside or lakeside use.

More than just bass

Beyond the raw power, the Boom 2 comes with a few practical extras. A built-in microphone lets it double as a speakerphone for calls.

If you want to expand coverage, PartyCast 2.0 lets you sync with other compatible Anker speakers for a multi-speaker setup. Microsoft's bet on small models for agentic AI is about…

The speaker also works as a power bank, sending up to 5W from its USB-A port to charge a phone or other device. That's not a lot of power, enough for a slow trickle rather than fast charging, but it's a handy emergency backup when you're far from a wall outlet.

What it doesn't do

There's no 3.5mm aux input, a common compromise in waterproof Bluetooth speakers where sealing the ports is critical. Playback is strictly wireless. That means anyone who needs a wired connection for lower latency or older devices will need a Bluetooth adapter. The specialization revolution: how smaller models are…

At $69.99, the Soundcore Boom 2 undercuts most comparable speakers in the 50W-and-waterproof category. JBL's Charge 5, for context, retails for around $180 and doesn't float. The trade-offs, no aux, slow phone charging, are minor at this price. This is a straightforward deal: if you need a durable, loud, waterproof speaker under $100, today's Woot sale is the one to buy.
