Bluetooth speakers with big sound and great features are hard to find for under $100, with most offerings being some variation of the same basic (and often small) design. Thankfully, through July 10th Woot has the Anker Soundcore Boom 2 on sale for $69.99, which is $20 cheaper than the discounted price at other retailers like Amazon, and about half its original $129.99 price. The waterproof Bluetooth speaker can run for up to 24 hours on a single charge, with big, bass-forward sound that’s great for a day by the water or just hanging out in the yard.

While size isn’t everything when it comes to Bluetooth speakers, the Soundcore Boom 2’s 50W subwoofer and pair of 15W tweeters should deliver louder, clearer sound than other speakers around the same price (which are often smaller). The IPX7 rating means it’s fully waterproof and submersible, and its design will let it pump out the tunes, or take calls with its built-in microphone, while it floats in water.

The Boom 2 has a robust set of features for a speaker at this price point. You can adjust the equalizer and the built-in lighting behavior from the Anker app, plus the speaker charges your other devices at up to 5W from its built-in USB-A port. Its support for Anker PartyCast 2.0 lets the Boom 2 sync with other Anker speakers for larger audio. There’s no 3.5mm aux input, which isn’t irregular for waterproof speakers, so it’s Bluetooth only for playback.
