The Ultimate Ears MEGABLAST is a portable Bluetooth speaker that comes with built-in support for Alexa voice assistant over a Wi-Fi connection. It's small and lightweight, and it even has an IP67 rating for dust and water resistance, though we don't currently test for this. This stereo speaker has a pretty neutral sound profile out-of-the-box, though, like many small speakers, it lacks low-bass. Fortunately, there's a graphic EQ and presets available in the Ultimate Ears app to help you customize its sound to your liking.
Our Verdict
The Ultimate Ears MEGABLAST is decent for music. Out-of-the-box, this speaker has a pretty neutral sound profile that's suitable for listening to lots of different genres. However, like many small speakers, it struggles to reproduce a thumpy low-bass, which can be disappointing if you like to feel the deep rumble in bass-heavy genres like EDM. You can also customize its sound profile using the graphic EQ and presets in the Ultimate Ears app.

The Ultimate Ears MEGABLAST is acceptable for videos and movies. Its balanced mid-range can reproduce clear and accurate dialogue. However, it lacks low-bass, so you don't really feel the deep thump and rumble in action-packed scenes. It can play stereo content, and its 360-degree design helps audio sound clear from all angles. While it gets pretty loud, unfortunately, there's some compression present when you play it at max volume.

The Ultimate Ears MEGABLAST is very good for podcasts. It has a neutral sound profile, especially in the mid-range, so dialogue is reproduced clearly and accurately. Thanks to its 360-degree design, it has excellent directivity, so audio is clear from all angles. This portable speaker can also get pretty loud, but unfortunately, there's some compression when you play it at max volume. You can also only pair it to one device at a time, which can be inconvenient.

The Ultimate Ears MEGABLAST is amazing for voice assistants. It has built-in Alexa support over a Wi-Fi connection, which you can activate using your voice. Alexa can hear you clearly even if you aren't very close to the speaker, and it does a decent job understanding you in a noisy setting. You can also mute the microphone by pressing the Bluetooth and the volume down buttons at the same time.

The Ultimate Ears MEGABLAST is good for outdoor use. This well-built speaker has a portable design and an IP67 rating for dust and water resistance, though we don't currently test for this. It gets pretty loud, too, but unfortunately, there's some compression when you play it at max volume. However, its eight-hour battery life is just okay, and it may not last through long days outdoors.

It can also last almost 24 hours from a single charge, though this can depend on your usage. However, the MEGABLAST is smaller, making it more portable.

Test Results
The Ultimate Ears MEGABLAST is a small, cylindrical speaker that looks very similar to the Ultimate Ears BOOM 3. It's meant to sit vertically, and it has two very distinct volume buttons on its front face. It comes in lots of different color variants. You can also purchase this speaker with a wireless charging dock, though we haven't tested it.

The Ultimate Ears MEGABLAST has an amazing build quality. It has a rubber top and bottom base along with a rubber strip down the middle for the volume buttons. The rest of the speaker is wrapped in a tight fabric, which doesn't seem like it would rip easily. It also has a tripod mount underneath, which is handy. It even has an IP67 rating for dust and water resistance, though we don't test for this. While it doesn't have an advertised IK rating, the manufacturer claims it's drop-proof from a height of one meter, though we don't currently test for this.
This speaker's controls are middling. There are volume controls as well as buttons for Bluetooth pairing and powering the speaker on and off. You can also press the Bluetooth and volume down buttons at the same time to mute the microphone. There's some audible feedback when you power it on/off and activate Bluetooth pairing, and there are lights to indicate the power status and the battery status. Unfortunately, there isn't any way to keep track of the volume level. There also aren't any controls that let you skip to the next track.

The Ultimate Ears app offers a graphic EQ and some presets so you can customize its sound more to your liking.

The Ultimate Ears MEGABLAST has a satisfactory battery performance. While it's advertised to last for sixteen hours, in our tests, it only lasted for a little over eight hours. However, battery life can vary depending on usage, so your real-world experience may vary. You can also use the app to set the power-saving feature to shut the speaker off after fifteen minutes, 30 minutes, 1 hour, 3 hours, or you can turn it off completely. You can charge it via the included micro-USB cable, or you can purchase a wireless charging dock separately. If a long battery life is important to you, check out the Ultimate Ears MEGABOOM 3, which can last over seventeen hours on a single charge.
The Ultimate Ears MEGABLAST has an incredible voice assistant performance. It has built-in support for Alexa over a Wi-Fi connection, which you can activate using your voice. The speaker can hear you clearly even if you're far away, though it doesn't understand you quite as easily as other Alexa speakers like the Devialet Mania if you're in a noisier setting. You can also press the Bluetooth and volume down buttons at the same time to mute the microphone.
The Ultimate Ears app is very good. It's compatible with both iOS and Android, and it comes with a graphic EQ and presets so you can customize the speaker's sound more to your liking. You can also use the app to manage multiple MEGABLAST speakers by creating a stereo pair or amplifying your audio across a large space or a party.
This speaker can't be used wired. While it comes with a micro-USB cable, that's just for charging the speaker.

Also, it has low latency when paired with iOS and Android devices, making it suitable for watching videos. Some apps compensate for latency differently, so your real-world experience may vary. If you're looking for a speaker that can be paired to two devices at the same time, check out the Bose SoundLink Revolve II.
The Ultimate Ears MEGABLAST is Wi-Fi compatible, so you can stream audio to it wirelessly over a Wi-Fi connection. However, it doesn't support Apple AirPlay or Google Chromecast.
