Compare the Ultimate Ears MEGABOOM 3 to the JBL Xtreme

It is hard against this comparison. The MEGABOOM and Xtreme are powerful Bluetooth speakers. I compare the speakers to different characteristics, such as the sound or design. The JBL Xtreme delivers the most powerful sound with the deepest bass, while the UE MEGABOOM is easier to carry in a bag.

The sound

Ultimate Ears MEGABOOM 3: powerful 360-degree sound

Thanks to the dual drivers and passive radiators, the Ultimate Ears MEGABOOM 3 effortlessly reaches a high volume. You place the speaker upright to take full advantage of the 360-degree sound. If you walk around the speaker, the sound will be clear from any position. The bass and treble are balanced on each volume. It was striking how realistic the vocal lines sounded. The bass is clearly present, but not as powerful as the Xtreme.

JBL Xtreme sound quality

JBL Xtreme: firm bass

The JBL Xtreme is equipped with double tweeters, woofers and passive radiators. As a result, the speaker not only delivers a room-filling sound, but the bass also sounds very powerful. You can see the radiators on the side vibrate to the beat of the music, which looks impressive. The speaker is more than a powerhouse, because at high volume the high tones remain clear. If you listen to a music style with a deep bass, the bass sounds come to the fore most. One thing is certain: if the bass can never sound strong enough for you, the Xtreme is for you.

The design

Ultimate Ears MEGABOOM 3: compact and shockproof

The UE MEGABOOM has a round design, like a tube. Despite the large size of 22.5 by 8.7 cm you can easily hold the speaker in one hand. The shock-resistant housing feels sturdy, but not breakable. The speaker weighs 912 grams. This makes it easy to take with you in a bag or backpack.

JBL Xtreme design

JBL Xtreme: heavier, but with shoulder strap

The JBL Xtreme is 28.3 cm wide and 12.6 cm high. With a weight of 2.1 kilos, the speaker is heavier than the MEGABOOM. This means that you can not carry it easily in a backpack. There is a handy shoulder strap included that you can attach to the housing. This way you carry the speaker like a bag wherever you go.

Water resistance

Ultimate Ears MEGABOOM 3: waterproof

The Ultimate Ears MEGABOOM 3 is completely waterproof. You can easily keep the speaker under water for half an hour to a maximum depth of 1 meter. Handy if you take the speaker on a boat or at the pool. Because you can easily clean the housing under the tap, the speaker is also suitable for a day at the beach or park.

JBL XTreme: splash-proof

The JBL Xtreme is not waterproof, but splash-proof. Do not let the speaker fall into the water. You can leave the device without risk in the rain or on the edge of the pool. Will there be dirt or sand on the housing? Then you can easily rinse it under the tap. With the zipper at the back you can prevent sand or water from entering the connections.


UE MEGABOOM operation

UE MEGABOOM: Link NFC and 50 speakers

In addition to Bluetooth, the MEGABOOM has NFC. You make a fast connection by tapping a smartphone that also has NFC against the speaker. You can change the volume with the large buttons on the housing, but the MEGABOOM app gives you more functions. You can adjust the sound of the sound with the equalizer or set an alarm. Another great feature is the Party Up mode. You make a stereo pair or connect a maximum of 150 speakers with each other so that the music sounds extra powerful.

JBL Xtreme control

JBL Xtreme: app for connecting 2 speakers

The Xtreme does not have NFC, so you connect it less quickly with your smartphone. There is an app that you mainly use for software updates and linking multiple speakers. In May there was an update with which you connect an infinite number of speakers. With the stereo function you let both speakers separately play the left and right channels. This allows you to listen to a realistic stereo image. Experiment with the distance between the two speakers and create the ideal sound result.


The speakers excel in different areas, so the comparison has no clear winner. Ask yourself what you find more important: ability or portability. With the JBL Xtreme you listen to the most powerful sound with the deepest bass. The Ultimate Ears MEGABOOM 3 is more compact and completely waterproof, making it easier to carry in a bag or backpack.
