Our favorite sub-$100 Bluetooth speaker just dropped to its lowest price ever

SAVE $40: As of Dec. 11, the Ultimate Ears Wonderboom 4 is just $59.99 instead of $99.99 at Amazon. That's 40% in savings and its lowest price on record.

Whether you need a Bluetooth speaker to blast holiday tunes during your gift-wrapping sessions this season or are looking for an affordable option for someone on your list, the Ultimate Ears Wonderboom 4 is the best speaker we've tested under $100. And we have good news: it just dropped to the lowest price It's ever been.

As of Dec. 11, the Wonderboom 4 is on sale for just $59.99 at Amazon, down from the usual $99.99. That's 40% in savings and beats its previous low by $10. It also beats its Black Friday price by $20.

This tiny powerhouse fits in the palm of your hand, but can get as loud as a larger speaker without losing much clarity. The fourth-generation speaker has less muddiness than the previous one, especially at higher volumes, as well as an Outdoor Boost Mode and Podcast Mode. Plus, it has a new USB-C port for easy charging. Otherwise, it's pretty much identical to the Wonderboom 3 (which we also loved). Like its predecessor, the Wonderboom 4 can survive drops from up to five feet and plunges into water for up to 30 minutes (thanks to an IP67 rating). It also packs a healthy battery life of 14 hours.

The only reason we'd pass on this speaker is if you already own the Wonderboom 3. Otherwise, at 40% off, we can't recommend the Wonderboom 4 enough. It comes in four fun colors and all of them are on sale.
