The Ultimate Ears MEGABOOM 3 Speaker is the perfect speaker for travelling. Thanks to the long battery life, the speaker can operate for up to 20 hours without a power supply. The loudspeaker can also be used for pool parties or boat trips, as it can be under water for up to 30 minutes. This doesn't happen as often because the loudspeaker is floatable. The sound quality is not neglected. Especially in terms of volume, the loudspeaker stands out from the competition.


  • Waterproof for up to 30 minutes under water
  • Long battery life
  • Simple operation with the MAGIC BUTTON
  • Good sound quality
  • Operation via App

The loudest in the test, with good - but not the best - sound quality.

The Ultimate Ears MEGABOOM 3 is perfect for outdoor activities where music is a must. The device is promoted with the IP67 protection class. The speaker floats and can easily be under water for up to 30 minutes, but only to a depth of one meter. The loudspeaker is also protected against dust and light dirt.

We have tested the model in the colour Night Black. The speaker is also available in the colours jungle green, Bengal red and blue lagoon.

Megaboom 3
The Megaboom 3 Bluetooth speaker is mainly controlled by the Magic button


The large "Magic button" is located on the upper small area of the speaker. Press once to pause or resume playback. Press twice to skip the current song and play the next song or track.

The two volume keys are located in the cross (louder) or in the dash (quieter) on the side of the speakers.

The Bluetooth key works just like those of comparable devices and is located on one side next to the Magic key. The on/off switch is located on the opposite side.

Megaboom 3
The connections of the Megaboom 3 Bluetooth Speaker


The popular and useful AUX connection (jack connection) is not part of this device. This means that the speaker cannot be connected to other audio devices, such as a TV or computer, without a Bluetooth connection. The only connection is a micro-USB port for charging the speaker. Most Android devices also have such an input. The charging cable of the Android devices can therefore also be used for charging the loudspeaker.

Megaboom 3 Bluetooth speaker
The Megaboom 3 Bluetooth speaker has its own app


The BOOM & MEGABOOM App can be downloaded free of charge from the App Store and Google Play. It provides additional useful functions. To use these, the device on hich the app runs must be connected to the loudspeaker via Bluetooth. This works very easily. An additional function is the PARTYUP mode. In this mode, over 150 Ultimate Ears speakers can play the same music simultaneously. The only condition is that they are all connected to a device that has the app. In addition, an equalizer adjustment and the setting of a music alarm is possible.

The Magic Button in combination with the app provides another unique feature. The Magic Button can be used to call up playlists directly. These must first be set as favorites in the app. Under iOS this can be done in combination with Apple Music and under Android in combination with Deezer. Spotify is not yet included. After the favorite playlists have been selected, the Magic Button must be pressed for a longer time and the music enjoyment can start. During the whole time the Smartphone must be connected to the loudspeaker via Bluetooth.


The operation with the almost invisible keys is not so easy to understand at the beginning. At first glance, it looks as if the loudspeaker only has one button. Th Design of theMEGABOOM 3 can raise a lot of sympathy.

Another big advantage is the long battery life, which can be up to 20 hours. Of course, this depends on the volume, among other things. Ultimate Ears states that the Bluetooth range is up to 45 metres. However, this range can only be achieved without obstacles between the loudspeaker and the player. In practice, it can be said that the range is already greater than that of the competition. The loudspeaker can easily be placed in the next room. The connection is usually not sufficient through several walls, even if the player and loudspeaker are less than 45 m away.

Sound quality

The sound quality shows that this is an up-to-date, higher quality Bluetooth loudspeaker. The MEGABOOM 3 easily pockets other devices that cost less than 150 euros. The more interesting question is, of course, whether the loudspeaker can beat the competition at around 200 euros in terms of sound. The answer to this question is yes. The Megaboom 3 doesn't differ so much from the predecessor in terms of sound quality.

The Ultimate Ears Megaboom 3 won the volume test. No other loudspeaker in the test can crank up the songs. However, the sound quality suffers from the high volume.

Optional accessories

  • Ultimate Ears also offers a charging station as an accessory. This charging station allows wireless charging of the speaker. This only needs to be placed on top of the charging station and can be quickly lifted again.
  • If you want to use Amazon's ALEXA speech system on your speaker, you can do the same. You can conveniently order Echo Input from Amazon and connect to the Ultimate Ears Megaboom 3 via Bluetooth.
  • There are also several pockets that are ideal for the Megaboom 3. We can recommend these bags.
