Ultimate Ears (previously branded as ‘UE’) just released the Wonderboom 2. This durable, portable speaker can only be described as a must-have for summer adventures. It’s the second generation of the Wonderboom line and it delivers big improvements in sound, battery life, and weatherproofing.

Wonderboom 2 Upgrades


Ultimate Ears Wonderboom 2 Candy

The Wonderboom 2 comes in vibrant dual-tones whereas the original is only available in single colors. As for size, this speaker is a little bigger than a softball; it’s small enough to clip to your bag or slip into your backpack without issue.

Honestly, the Ultimate Ears Wonderboom 2 is adorable—it looks like a giant piece of candy. If a fruit Tootsie Roll and a DK barrel had a baby it would be this speaker. Let the record show that I love both candy and Donkey Kong so this is high praise.

Outdoor Boost

One of the coolest new features is the addition of “Outdoor Boost.” When you press the little tree button on the bottom of your device, it activates a different sound experience better suited to the boundless expanse of nature. The speaker’s built-in, pre-adjusted equalizer plays to its surroundings and delivers louder, crisper sound to accommodate for the acoustics.

Battery Life

The Wonderboom 2 can play nonstop for 13 hours whereas its predecessor could only last for 10. That’s 30% more time DJing at the beach or blasting music at a backyard party. You can also pack a power bank for portable charging.

Ultimate Ears Megaboom 2 waterproof


It’s likely that you’ve come across a waterproof description that reads “IPX” followed by a number. However, if you don’t know the in-depth workings IPX standardization (and honestly why would you?) that number doesn’t mean much.

An “IP” rating is a numeric system set by the International Electrotechnical Commission. It tells you how “dust resistant” or “waterproof” an item is based on a series of physical tests. The format is: IP(dust #)(water #).

The new speaker has a rating of IP67. “6” is the highest dust-resistant rating a device can have. It means that this speaker is totally protected if you take it to the beach or it accidentally falls into some dirt when you’re camping. Like the original, thanks to its ‘7’ water resistance rating the Wonderboom 2 can be submerged in up to 1 meter of water for 30 minutes.

Thanks to its true wireless capabilities, the Wonderboom 2 connects with two source devices simultaneously; you can wirelessly stream music from either one. Alternatively, you can connect with two Wonderbooms from one source from up to 100 feet away.

Final Thoughts

The Ultimate Ears Wonderboom 2 has notable updates from the original and you can get it for the same price ($99.99). It’s louder, more rugged, waterproof, has excellent battery life, and more color options. All things considered, the Wonderboom 2  is definitely a worthwhile investment.
