Best Portable Speaker EVER - Here's Why!
I have used and abused my Mega Boom 3s for over four years and other models even longer with nothing but success. People compare them to bose and other brands but they are incomparable and here's why. I have put these speakers through 125f summers sitting in the cab of a car pushing 140f inside. They do have a heat sensor that tells them to not turn on. So I dunked them in my ice water filled cooler for a few minutes and bam good to go. I pressure wash my sand covered golf cart with the speakers playing in the cup holders, pressure wash the speakers too, played the entire time and clean as new. I have dropped them off tailgates, coolers, ladders, still pushing. I have thrown one in a pool, still good. I mostly use them in Baghdad where I work and they push straight through the summer with impressive battery life in the heat. They sound exactly as good as the similar model bose, I compared and played two and two around a pool, but half the price and one hundred times the durability. I pair mine year-round, and now one auto-connects as the master and the other always connects as the slave every time I turn it on, so I never even have to open the app. This feature is amazing. Everyone always asks me about these speakers because they sound so good when paired offering a pool, patio, golf cart, or bedroom stereo quality sound. Truly there is no next step beyond these speakers with portability as they are the best sounding and still capable to be utilized outdoors safely. The only speakers that sound better all lose the imortality this speaker offers. I have never owned any other electronic I could literally pressure wash the dirt off, its insane. I have other models I take kayaking and abuse to mud, sand, and a LOT of water, still work like new. Biggest tip, attach a very large carabiner to the fabric loop. I hang mine from everything, everywhere, at all times. And dont get one, get two at a minimum. That is where the joy really comes in. My one complaint, the system needs a hair of time to process sound, so if you watch them with a movie they are slightly behind the video. Update: October 2024. These speakers still blow me away. I am coming up on purchasing six of these since now everyone wants one as a gift when they hear them. I have put them through countless sandstorms and now I leave them outside 24/7 where they are subject to rain, dust, wind, and direct sun. I pressure wash them twice a week and then wipe down with a wet rag. I used to bring them inside, but it seems there is no need since they just keep on working without issue. I jump in my cart, push their power buttons, look at my phone and spotify pops up recommending hitting play, I hit play, and both speakers are playing in sync. I don't have to open Bluetooth, don't have to open the app, nothing. They all reconnect due to its memory of playing the last session.

Very good sound for a portable speaker!
OK, happy again. It is 4/24/2024. Just found the option in the Android app was restored, which allows turning-off the battery-draining remote-on feature!! The feature (switch) in the app is marked "new", so this looks like a recent development. Happy to give 5 stars now. Speaker has been rock solid for over a year, and sounds great. Had another (newer) speaker die some months back (wouldn't turn on), so happy this one is going strong. Wouldn't have been so fussy, but with these portable speakers, the battery is "do or die". Being fair, the battery drain wasn't "that bad", but was still a problem. ------- Updated 6/14/2023 ------- Very unhappy with Megaboom 3 now; down-rating to 2 stars (not 1) since the sound is good, but downgrading from 5 due to "battery drain". Apparently there is some sort of "always on bluetooth remote" feature that drains the battery, even when not in use. Since I only use this speaker when I want portability, this is a MAJOR SHOWSTOPPER for me. In researching, I find posts saying that the app could formerly disable this feature, but that the feature can no longer be disabled (as-of several years ago). In the future, I'll stick with JBL or Oontz. NOT happy. ------- Original Review -------- Very happy with my Megaboom 3. I "drive" it from a Samsung Android phone, with the "rock" EQ selected in Android settings. No EQ from Megaboom app: just flat. While I know these speakers (all brands) struggle with bass, as a bass-player that grew-up with 200W and 2x15" speakers, I can't complain when tiny speakers struggle with the low frequencies. It's basic physics. I have nice headphones and a bigger bluetooth speaker, I never lug around, but for the small speaker I wanted for portability, it is very nice. My use-case is indoor, mid-volume. 12W probably won't "shatter windows" outside, but I don't need that. I certainly prefer the sound the Megaboom 3 to my Beats Studio Buds. Bonus: You can replace the battery! The Bose Soundlink Color I am replacing does not have an easy battery replacement.

I love this speaker. I purchased it five years ago and it's still going strong. I had a Bose before I bought the Megaboom. The battery on the Bose no longer took a charge after only two years. It started weakening in a year. I thought about tearing it apart and soldering in a new battery but decided to get the Ultimate Ears after my husband purchased the little Ultimate Ears version. I liked the sound and the battery lasted considerably longer than the Bose when new. This U E Megaboom battery seems as good today as it did they day I bought it. It has great sound, takes a beating and I'm not worried about it when I'm by the pool, on the beach or stuck in the rain on a boat or canoe. I would definitely buy another Ultimate Ears Megaboom if this one ever gives up the ghost. Now paired with my Pixel 7, the Bluetooth distance is great. It's the phone that made the real difference in distance. My old phone was half or less than what I get now.

We have the Sonos sound system for use throughout our house which we love, but we were looking for a portable speaker that we could take out to the cottage, gardening, etc. I have heard some of the other portable speakers on the market and was mostly disappointed as the sound was a little tinny and seemed to echo. Also, I have seen problems with connecting additional phones to the speaker. For the price, I can't believe how great this speaker sounds. We first tested it in our great room, and were pleasantly surprised at the clarity. We have since used it outdoors and again have enjoyed it. We downloaded the app to our phones and connectivity was simple. Although the speaker is bigger than others, I think the sound justifies the size. So far battery has been great. This wasn't the cheapest route, but we checked a number of sites for quality ratings, and it constantly was in the top. Both my husband and I are enjoying the speaker.

This amazing speaker is worth the money!!! You want a speaker that has amazing sound, a great look, that pairs easily, that floats on water and is waterproof, that is easy to use and comes from a reputable brand? You’ve got it all. One thing to note is that you need to download the app to pair it, but besides that. It’s the easiest to pair. You can sing up to two decided on it and pair it to multiple other boom speakers. Although, if I’m not mistaken, you can only connect it to megaboom speakers. If you want to compare it to other UE speakers, I would recommend going to the website. They have an amazing table that lets you compare all their speakers! If you want to be the person with the cool speaker at the party, go with this one. I’ve never seen one this simple and that has such good sound quality.

This speaker has plenty of volume & sounds good in all directions. But I had to go into the eq settings & crank the bass up.. otherwise it would be a little lacking. I like the speaker & would consider getting another one to stereo pair with it.

Large size produce higher volume with a good balance of base and treble and the ability to adjust those sounds . Sound not quite up to bose or B&O ...however for the price it is a very good speaker .
