The original Ultimate Ears Wonderboom was a tiny and cute little portable Bluetooth speaker that could float on water and sounded pretty decent — all for just $100. There was little not to love about it, a sentiment echoed by Jeff in our review. It must have been a good seller for UE owner Logitech, too, as it's seen fit to bring out an updated version with better sound and more features.

Probably the most important new capability offered by the Wonderboom 2 is stereo pairing. You were able to connect more than one speaker with the previous generation, but stereo sound wasn't possible. Now you can pair two of them and throw them in the water for a full-on stereo pool party. A new feature called Outdoor Boost enables an EQ setting specifically designed for louder and crisper outdoor audio, and the bass will also generally be beefier.

The ingress protection rating has been upgraded from IPX7 to IP67, meaning the Wonderboom 2 is now dustproof as well as waterproof. Battery life is also improved, with UE promising 30% more than the 10 hours offered by its predecessor. The new speaker isn't that visually distinct from the first gen model, but it comes in the following unnecessarily named colors: Deep Space Black (Black), Crushed Ice (Grey), Radical Red (Red), Bermuda Blue (Blue), and Just Peach (Pink). "The kids" will love those names, I guess.

Pricing thankfully stays the same as the original Wonderboom, at $99.99/£89.99/€99.99. It's available for pre-order on the UE site in the US, the UK, and Europe. also stocks it.
