The breakdown

Pictured: Ultimate Ears Wonderboom (left) and Bose Soundlink Micro.

The Ultimate Ears Wonderboom and Bose SoundLink Micro are very similar. They’re both water-resistant to allow for submersion in up to 3 feet of water for 30 minutes, and they’re both ruggedly made to withstand any travel, outdoor activity, or party.

Where they truly differ is in sound quality, price, and battery life. The Bose SoundLink Micro has a warmer, deeper bass and is altogether better balanced in an audio sense. It’s also, on average, $30 more than the Ultimate Ears Wonderboom, but it’s 6-hour battery life is just over half that of the Wonderboom.

For most people, the Ultimate Ears Wonderboomis the better option. While it may not boast the excellent sound quality of the Bose SoundLink Micro, it still holds its own just fine. If the SoundLink Micro is a 10 in sound quality, the Wonderboom is a 7 for the discerning and a solid 8 for everyone else.

Though the SoundLink Micro has impeccable bass for its size and full control through the Bose Connect app, its short, 30-foot Bluetooth range and 6-hour battery life are weak for the price. There are also only three fairly basic colors to choose from, while there are tons of color options for the Wonderboom.

If you want to play all day, pair up two speakers, and want to be able to control your music from further away, then the Ultimate Ears Wonderboom is the one to go with. At $60 to start, it’s an excellent value and is the best choice. However, if sound is most important for you or you already buy into the Bose brand, then you won’t go wrong with the SoundLink Micro.
