About the Ultimate Ears MEGABOOM 3

Bigger, badder bass

“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.

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.

Customer Q&A

5 questions already asked

Will this speaker pair with a Yamaha r-n303 receiver?
[ Frank  Apr 25, 2020 ]
1 answer
Yes, the Yamaha R-N303 can does offer Bluetooth transmission out to most any Bluetooth headphone or speaker. To use this feature, the receiver must be connected to your home network and you will need to use MusicCast Controller app on your Apple iOS or Android device to configure the receiver as a Bluetooth transmitter. Please chat with an Advisor online or by phone at 1-800-324-9695. We will be happy to answer other questions regarding this receivers Bluetooth transmission capabilities.
[ Jess  May 18, 2020 ]  Staff
Can anyone offer their experience with using these speakers as a stereo pair with Bluetooth and the MEGABOOM app? Specifically looking for Android user experience. I have a pair of JBL Pulse 3 which can supposedly do this but the JBL Connect App is pathetic when used with Andriod devices, almost never get successful stereo pairing. I can almost always make stereo pairing work with my Apple devices but get poor playback results (dropouts, jitter, etc) after a brief period of clean playback.

Spent 1 1/2 hours on the phone with Crutchfeld this morning trying to pair them up, unsuccessfully. The guy helping me on the project decided one of them was malfunctioning and sent me a shipping label send it back. They are sending out s new speaker. I have an I-Phone. It recognized two speakers line with Bluetooth. It simply could not get the second speaker to sign on. The one speaker that hooked up sounds good, no dropout or jitter. However, I wanna pair that can work in Stereo also. We shall see what happens with the new speaker.
[ Katherine  Dec 07, 2019 ]
My megaboom speakers are mono speakers and have no provision to change to a left / right speaker when two are used together. So if you are asking if I have used two megaboom speakers as true steroids speakers I have not. I do have a megaboom 3 and UE megaboom speaker and occasionally play them as a pair and do not have issue when I do.
[ BRUCE  Dec 06, 2019 ]
How does this compare to the original mega boom? Curious to know if it is worth an upgrade?

Lindsey, I cannot answer as never had a Megaboom, but can tell you very satisfied including comparing to my Sonos 3s. Dale
[ Dale  Dec 15, 2018 ]
The Megaboom 3 has spectacular sound and I'm really enjoying it. I can't answer the question as this is the first megaboom I've owned. The 3 is worth the money spent.
[ BRUCE  Dec 15, 2018 ]
I have old one and I just brought the latest one. They both still sound great and the new mega boom seems to sound better. I have paired them together and wow they broke the sound barrier.
[ Gil  Dec 15, 2018 ]
I have both. In terms of sound there are almost identical with the 3 heading a bit more towards clarity and the original more to bass. I like the hook tonput it hanging on the 3 better. The original has a hook on the underside. One advantage of the original is that it has a plug to connect a 1/8" cable which I use in my projector for outdoor movie night. The 3 is strictly bluetooth.
[ Jose  Dec 14, 2018 ]
I have no knowledge of the original mega boom. The sound is crisp on the mega boom 3. The bass is so so. It works for me for what I am using it for.
[ Marlice  Dec 14, 2018 ]
I only upgraded because I lost my original megaboom. If you still have the original megaboom, stick to it. I feel the original was a bit louder, but megaboom3 has a bit more bass imo. The app could use a refresh, currently on android phone and do not have deezer account. I just have Amazon Music, Spotify, and Pandora.
[ Mark Angelo  Dec 14, 2018 ]
will the megaboom 3 link for a true left and right stereo?
