Our take on the Ultimate Ears MEGABOOM 3

“The bass is more than I could have imagined!” That's what one of our customers said about the original MEGABOOM. Well, imagine even more bass. The re-designed Ultimate Ears MEGABOOM 3 delivers fuller, richer lows than the original. And with up to 90 dB of volume, it can really pack a punch.

Bigger, badder bass

All weather, all fun

The MEGABOOM 3 is completely waterproof, dustproof, and sand-proof. So you can party on the beach, on the slopes, or poolside. Don't worry if it gets knocked into the water. This speaker can withstand submersion down to three feet for up to 30 minutes. And with a 20-hour built-in battery, it might just outlast your party.

App control

The Ultimate Ears BOOM & MEGABOOM app gives you lots of options for your speaker. In the aptly named #PartyUp mode, you can stream simultaneously to up to 150 compatible Ultimate Ear speakers. Party up indeed!

You can also simultaneously pair two devices, so you and a friend can co-DJ. The app lets you adjust your speaker's EQ settings. Even use it as your wake-up alarm with tunes from Pandora® or Spotify® Premium.

One-touch Magic Button

With a wireless pairing range of up to 150 feet, there may be times when you're much closer to your MEGABOOM 3 than the smartphone that's playing the music. For those times, the single top-mounted Magic Button lets you pause, play, and skip tunes. If you're streaming from an iPhone® or iPad® you can even cycle through preset Apple Music® and Deezer® Premium playlists with just that one button.
