REVIEW – It’s been a while since I reviewed a wireless speaker. I’ve heard good things about Ultimate Ears speakers, and I wanted a speaker that was portable, waterproof and could replace the Echo Dot that I currently use in my living room. The UE MegaBlast meets all these criteria so I decided to give it a listen.

What is it?

Ultimate Ears MegaBlast is a portable WiFi/Bluetooth speaker with 360º sound and built-in Amazon Alexa.

Design and features

The MegaBlast’s design is similar to other offerings from UE. Cylindrical with rubberized surfaces wrapped in acoustic fabric with those signature oversized volume control buttons on the front. It stands vertically, so it takes up less space.  It’s aesthetically pleasing without being obnoxious, and it comes in cool colors. I choose to review the Merlot Red, it’s also available in Graphite, Bluesteel, and Blizzard.

MegaBlast is UE’s biggest speaker to date coming in at just under 91/2-inches tall. It has a little heft to it but is still extremely portable.

The on/off button, Bluetooth indicator LED, and LED power/Alexa indicator are located on the top of the speaker.

On the bottom, there’s a D-ring that when removed reveals a standard tripod mount insert. The Micro-USB charging port is located under the rubber weather door. There’s also a charge LED.

MegaBlast can be connected using both Wi-Fi and Bluetooth. Using WiFi, you can control your music with your voice. Or control Wi-Fi quality streams directly from music services such as Spotify and Amazon Music. When you’re away from Wi-Fi, you can use your smartphone or other Bluetooth devices, minus the voice control of course.

MegaBlast can be paired with other MegaBlast or Blast speakers for louder, more immersive sound. Using the app, you can instantly connect up to eight speakers in total.


The speaker has an impressive IP67 waterproof and dust-proof rating, which means it can be totally submerged in water for up to 30 minutes.

It’s also drop-proof, something I put to the test within my first hour of use. I accidentally knocked the speaker off of a countertop, it fell about six feet to the ground and came away with only a small scuff mark. Whew!

I also like the fact that if it gets dirty, you can just rinse it off and let it air dry.

Battery life

MegaBlast also boasts an equally impressive 16-hour battery life. I can’t speak on the 16 hours, but listening to music using Wi-Fi for over 2 hours at a medium volume it went from 100% to 90%. Not bad. However, when using Bluetooth, the battery went from 100% to 50% over the same time span. That’s not so good.

To check the battery percentage of the speaker, you can use the app or simultaneously press the + – buttons.

Power Up wireless charger

Speaking of battery life, UE also sent me one of their Power Up wireless chargers. The small white disk is the same size as MegaBlast’s base and it can be used anywhere it can be plugged in.

It comes with a charging D-ring that replaces the MegaBlast’s standard D-ring. To charge simply place the speaker onto the Power Up.

A small LED indicator on the front will blink to let you know that the speaker is charging. When the battery is charged, the light will remain solid. You can also use the speaker while it’s charging.

The Power Up allows me to keep the speaker on 24/7 so I have access to Alexa without having to worry about running down the battery. And when I grab the MegaBlast to take it into another room or outside I know that it’s fully charged.

It also means no more remembering to plug or unplug the speaker.

IMO if you plan on getting a MegaBlast, the Power Up is a must-have accessory and worth the $39 price tag.

Setup and Blast app

To set up the speaker, download and launch the Blast app then follow the instructions. With the Blast app, you can control volume, EQ settings, add and create speaker groups, and check the speaker’s battery and connection status. The app has a nice interface and is easy to navigate.

Say hello to Alexa

One of the MegaBlasts biggest features is that it comes with Amazon Alexa built-in. To enable Alexa, all you have to do is sign into your Amazon account using the Blast app during setup.

When you say the wake word “Alexa”, the indicator light on top of the speaker glows brightly indicating that she’s listening.

The only problem with that is if the speaker is across the room, it’s hard to know if Alexa is hearing you, might be nice if there was an audible tone indicating Alexa is listening.

Otherwise, it works pretty much like my Echo Dot. I can use Alexa to control my lights and smart lock, set a timer,  control my music or access one of Alexa’s growing range of skills.

The best thing is being able to do all these things wirelessly as long as your connected to WiFi or a mobile hotspot (Alexa does not work using Bluetooth).

I like being able to take Alexa with me from room to room. And being able to control my music without having to fumble with my phone is a definite plus.

Here’s a link to all the music services you can control using Alexa.

I did run into one issue. When playing music at a high volume, Alexa had trouble hearing me even at close range. Hopefully, this is something that can be addressed with a firmware update.

If you don’t want Alexa listening to you, you can enable Alexa Privacy Mode either through the Blast app or by simultaneously pressing the volume down and Bluetooth buttons.

Sound performance

With a name like MegaBlast, you would expect this speaker to get plenty loud, and it does. But it does so without losing any of the music’s clarity. What you get is a rich, vibrant sound that is well balanced.

MegaBlast also delivers that bass but in a way that’s not over manufactured or fake sounding.

The design of the speaker allows it to radiate music 360º, and it fills the room with sound. You feel like the music is surrounding you instead of coming directly at you.

You can use the Blast app to choose from 5 different preset EQ settings. The Standard, Custom, Voices, Cramped Spaces, and Bass Jump. I recommend using either The Standard or Custom to get the best sound.

I’ll be the first to say I’m not a music snob or audio aficionado. But to me, the overall listening experience with the MegaBlast is excellent.

What I like

  • Cool design
  • Portable
  • IP67 waterproof
  • Durable
  • Built-in Alexa
  • Works with both Wi-Fi and Bluetooth
  • Very good room filling sound
  • Power Up wireless charger (sold separately)

What needs to be improved

  • It’s hard to tell if Alexa is activated
  • Alexa has trouble hearing you over loud music

Final thoughts

The UE MegaBlast is the best sounding wireless speaker I’ve ever used. The built-in Alexa feature, while not perfect, is still very good and it sure beats my Echo dot for sound and of course portability. The only major issue I have is Alexa not being able to hear me when I listen to music at a high volume.

  1. Gadgeteer Comment Policy - Please read before commenting
  2. It would have been helpful to compare this with the Echo Tap (for which there is a charging dock). I believe the Tap has been discontinued, but owners might be considering a portable replacement.

  3. Thanks for the review. Spent most of today looking and different wireless speakers and was norrowing down. This made a lot of my research worth while…

  4. Have a megablast myself and here are a few tips, if you run it from a solid 3.v you will be able to get the megablast to 100db instead of the stock 93db cap. If you can find yourself a 60 or 70 litre esky, stand it on its side without the lid and place the megablast inside of it and it doubles the bass instantly. Completely transforms the sound, and having held a sound Meyer next to it, whilst in the esky the Meyer was reading 106.5db and this is huge considering the size of the actual drivers the megablast has in it. All in all it is a cool speaker and I too am very happy with mine.
