Ultimate Ears BOOM 4 Reviews

Great speaker, but need the app

Speakers work great, but it's disappointing that the app is required to play in "Party Mode" and the app can only be downloaded on very specific operating systems

Top notch sound!

Great speaker! It is super loud for its size and it works great.
