Blast your favorite music wirelessly with the Wonderboom speaker on sale for $40

Ultimate Ears' WONDERBOOM is a Bluetooth speaker that was designed to be brought just about anywhere. It's super compact, very durable, and even waterproof. While it originally sold for $99.99, you can pick up the Phantom Black for just $39.99 at Best Buy today. We have seen regular price drops on a bunch of colors recently with $70 being the average sale price.

Today's sale also originally included the Subzero Blue model, though unfortunately it's recently sold out. The Phantom Black model might not last much longer either, so don't miss this chance to save! Today's deal matches the best deal we've ever seen offered for these speakers, so you'll be hard-pressed to find a better offer before the holiday season is over.

The Ultimate Ears Wonderboom Bluetooth speaker makes a great pick to use indoors or outside. It's waterproof, can be paired with more speakers for even bigger sound, and lasts for up to 10 hours on a single charge.

This USB-rechargeable Bluetooth speaker sends out sound in all directions with its 360-degree design, while offering 10 hours of battery life per charge. The 'Boom' in capital letters within its name is no joke either, this speaker is loud, and the best part is that you can bring it just about anywhere, whether that's to the beach, to a party, on vacation, or even in the shower. It can float, too, and can be paired with another WONDERBOOM if you need to kick the tunes up a few levels.

While the WONDERBOOM 2 is the newest Wonderboom speaker to hit the market, it's on sale for just $69.99 right now. There are a few improvements that might interest you like its ability to provide stereo audio when paired with another WONDERBOOM 2, as opposed to the original model which only allows for mono audio when paired.

Shipping at Best Buy is free on orders totaling $35 or more, though you could also select free in-store pickup where available if you'd like to recieve your order even faster.
