The Ultimate Ears MEGABOOM 3 is a portable Bluetooth speaker designed for use both indoors and outside. It has a 360-degree design for a consistent listening experience from all angles and an IP67 rating for dust and water resistance. Its small size makes it easy to carry around with you, and it comes in several different color variants to suit your style.

Our Verdict

7.0 Music

The Ultimate Ears MEGABOOM 3 Bluetooth speaker is decent for music. It has a boomy sound profile with lots of high-bass, but struggles to produce adequate thumpy low-bass. Vocals and instruments sound present and clear, but an underemphasized treble range loses some of the detail found in higher frequencies. If you want a different sound, its companion app has a graphic EQ with presets to customize the mix. Its 360-degree design also means consistent audio delivery from every angle.

Pros
  • Wide and spacious soundstage.
  • Graphic EQ in its companion app.
  • Remarkably long battery life.
Cons
  • Lacks low-bass.
  • Some compression present at max volume.
6.2 Videos/Movies

The Ultimate Ears MEGABOOM 3 is passable for videos and movies. Though its sound profile is boomy overall, it has a fairly balanced mid-range, so dialogue sounds clear and present in the mix. However, it lacks low-bass, so you don't feel the deep thump and rumble in action-packed movie scenes. Its low latency with Android devices is suitable for watching videos, but the speaker doesn't perform as well with iOS devices. That said, some apps compensate for latency differently.

Pros
  • Wide and spacious soundstage.
Cons
  • Lacks low-bass.
  • High Bluetooth latency with iOS devices.
  • Some compression present at max volume.
7.6 Podcasts

The Ultimate Ears MEGABOOM 3 is good for podcasts. While it has a boomy sound profile, the mid-range is well-balanced, so dialogue is reproduced accurately. However, its treble range is underemphasized, so sibilants like S and T sounds are dark and dull. It lasts nearly eighteen hours on a single charge, so you can listen to several long episodes without worrying about losing power. Unfortunately, you can only pair one device at a time over Bluetooth, which is inconvenient if you like to take turns DJ'ing with your friends.

Pros
  • Incredibly portable.
  • Remarkably long battery life.
Cons
  • Doesn't support multi-device pairing.
3.2 Voice Assistant

The Ultimate Ears MEGABOOM 3 doesn't have voice assistant support.

7.9 Outdoors

The Ultimate Ears MEGABOOM 3 is very good for outdoor use. It has an incredibly sturdy build, and it's lightweight and portable. Thanks to its 360-degree design, it fills the air with sound from all directions, which is great for parties outside. It has an IP67 rating for dust and water resistance and floats in water, making it well-suited for poolside use. Its nearly 18-hour battery life also lets you use it all day without having to charge it. Unfortunately, it doesn't get especially loud, and there's some compression present at max volume.

Pros
  • IP67 rating for dust and water resistance.
  • Incredibly portable.
  • Wide and spacious soundstage.
  • Remarkably long battery life.
Cons
  • Some compression present at max volume.

It can also get much louder with significantly fewer compression artifacts at max volume, resulting in cleaner audio at louder volume levels. Additionally, it has a longer battery life, lasting just under 24 hours from a single charge, though this can depend on your usage.

This speaker has sub-par controls. There are a few buttons on the top and sides that are all textured and give good feedback when pressed, including chimes for powering the speaker on and off.

The volume buttons on the side are very large, and there's a chime to indicate when you've reached max volume. However, you need to be sure you press the center of each button to input commands. Nothing indicates the current volume level or when you've reached the minimum volume.

The 'Magic' button on the top of the speaker lets you control audio playback and is pretty simple to use. Still, there's no command to let you return to the previous track.

The Ultimate Ears MEGABOOM 3 has passable frequency response accuracy. When using the 'Standard' EQ preset in its companion app, it delivers a boomy sound with lots of high-bass. However, it struggles to reproduce a thumpy, rumbling low-bass, especially compared to the Ultimate Ears EPICBOOM. The mid-range is fairly well-balanced, so vocals and lead instruments sound clear and present in the mix. However, the higher frequencies of these instruments sound dark due to the underemphasized treble range. Fortunately, the Ultimate Ears app has a full graphic EQ and presets, letting you customize its sound profile.

However, while it has low Bluetooth latency with Android devices, its Bluetooth latency with iOS devices is high, so it may not be suitable for watching videos on paired iOS devices. Some apps compensate for latency differently, so your experience may vary.

Note: While the manufacturer advertises that this speaker can connect to two mobile devices simultaneously, we couldn't make this feature work, as our unit kept disconnecting from one device when trying to connect to the second.
