Review Ultimate Ears Megaboom 3 Bluetooth speaker: resistance and lots of sound [análise/vídeo]

THE Megaboom 3 is the most powerful Bluetooth speaker from Ultimate Ears currently in Brazil. To compete with JBL models, the speaker offers 360º sound, an application dedicated to equalize, in addition to a long battery life and resistance to falling. It still has wireless charging as a differentiator, but this you must purchase separately, unfortunately. On the official website of Logitech, owner of the EU brand, Megaboom 3 appears for R $ 999.

Is it worth it? Is she all that they say? Is the sound powerful? Megaboom 3 was my co-worker here at Tecnoblog and now I share my impressions in this complete review.

Design and connectivity

Megaboom 3 remembers past generations and even Wonderboom 2, whose analysis is now available on Tecnoblog. I know that the cylinder shape divides opinions, as do the huge buttons on the side. However, the care of the brand with the construction and the well done finish makes me like this speaker even more.

For this analysis, we received the ultraviolet purple version which has a gradient effect when light reflects on the fabric. Black (Night Black), blue (Lagoon Blue) and red (Sunset red) options are also available. Since I spoke of the fabric, Ultimate Ears says that the “textile performance of the speaker is developed for the extremes”, which is why it uses the same material as “firefighting team clothes” and “motorcycle jackets”.

The speaker is waterproof, drop and dust proof as it is IP67 certified. In addition, for the clumsy on duty, Megaboom 3 floats in the water, as does Wonderboom.

In short, the whole project is worthy of note 10. However, its weight, 925 grams, bothered me a little and can cause some discomfort during travel. Still, I will keep my top design score.

Speaking of connectivity now, it is sad to see a product so well developed with a micro USB port hidden at the bottom. The Bluetooth connection is efficient and stable, without those cuts in the sound that usually appear in some boxes of the competition. I also did tests with videos and I noticed that the latency here is low.

It can be controlled by the Boom & Megaboom app, available for Android and iPhone. In it, you can turn off the Megaboom 3, control the volume, check the battery level and even set an alarm, which is quite different. You set the time and it automatically sounds a sound to alert you – there is an unusual but useful feature.

Still on the app, it is possible to integrate it with your favorite audio streaming platform, however there are limitations: the feature only works with Apple Music, Amazon Music and Deezer, leaving aside the popular Spotify. Another negative point is that Boom & Megaboom is not available in Portuguese, only in English, French, Spanish and German.

Sound and battery quality

Now let’s get to what really matters: Megaboom 3 is a powerful speaker. So much so that you don’t even have to leave the volume above 50% to hear your songs and podcasts clearly, thanks to its 360º performance, an important differential that favors dispersion in large and closed environments.

I Follow Rivers, by Lykke Li, in its most agitated version, sounds with striking bass, clear vocals and I didn’t notice any noise during the whole track, not even when I raised the volume to 90%, which is extremely loud in this box. Calmer music, like Paradise, from Coldplay, seems to be more vigorous, maintaining a good balance between vocals and instruments, without congestion.

However, in Love Of My Life, from Queen, it is possible to notice a lack of stability in the midfielders, conflicting with the vocal. This is usually more noticeable in quiet songs.

The tests I shared now were done without any adjustments, but you can customize as you like through the equalizer in the Boom & Megaboom app. There are some pre-defined modes there and the user is free to make changes.

And as I said before, the EU Megaboom 3 is very powerful, but if all that strength is not enough, you can pair it with other boxes from the brand, for a more immersive experience.

To control the songs, the company added the Magic button at the top, to play, pause and, by pressing it twice, I can change tracks. Next to it are the Bluetooth and on / off buttons.

With regard to autonomy, Ultimate Ears promises up to 20 hours of playback, that is, 5 hours more than Boom 3 and JBL Xtreme 2, and 4 hours less when compared to Sony SRS-XB41. Daily, I left Megaboom 3 playing music for about 8:30 am with the volume at 30%. On the sixth day, they still had 40% battery in the morning, a very good result.

Even the box itself recognizes when you are not touching anything and automatically turns off to save energy.

As for charging, we can highlight two points: the first is the 18 watt plug adapter included in the box, however there is a problem, it does not follow the Brazilian standard and is type A; second point, Megaboom 3 has its own wireless charging system, the white base is attached to the bottom of the gadget and promises more autonomy. However, the accessory is sold separately and costs R $ 150.

Ultimate Ears Megaboom 3: is it worth it?

Yes, it is worth betting on Megaboom 3 and it is a good alternative for those who are not very fond of JBL models. Ultimate Ears was able to develop a Bluetooth speaker with impeccable performance, the bass is balanced and the treble sounds clear. The only problem, even, are the mediums that tend to conflict with the vocal in less agitated tracks, which can bother more detailed users.

In the visual, it is possible to notice a beautiful work of design and construction. In addition, it has excellent autonomy, it is waterproof and falling, this is a differential. Compared to its rival, JBL Charge 4, Megaboom 3 stands out for offering in-box charger, wireless charging and a more complete app.

Charge 4 has USB type C, 3.5 mm jack and can also function as a power bank, essential features that this EU model does not deliver. The LG Xboom Go PL7 is another interesting and more affordable option, with battery for up to 24 hours of playback, multicolored lights, but it doesn’t have 360º sound. Now it’s up to you!
