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.

Best speaker!
Love this speaker to the point that I got another one! You are able to connect both speakers via the app and it sounds amazing! I love the fact that you can turn it on just by using the app!

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.

5 years and still kicking
Five years of use, still works great. Very durable, excellent battery life still. Worth every penny. We take it camping a lot, beach, river, etc. Its been dropped, kicked and left out in the rain. The app is also great to tune the sound.

Great Practicality, Good Sound
This speaker is just amazing. I've had it for almost a year now and I'm really happy with my purchase. Overall, sound quality, size, build quality and features is just perfect. The speaker packs an immersive sound and the size is perfect (big enough to put out rich sound but not too big, perfectly portable). Innumerable times I've let it fall, yet it only has minor cosmetic damage. Very easy controls and the app has is very simple design, with PartyUp which works amazing too (I have a Hyperboom and these two sound incredible together). The reason why I only gave it four stars is because at high levels, depending on the song obviously, this speaker tends to compress the sound so that it doesn't distorts, which makes it have volume fluctuation on the highs (when the kick hits, for example), so this sacrifices sound balance for undistorted sound. It happens only at max volume and is really not that noticeable so it doesn't affect sound quality. This is not something to worry about for general consumers though, only audiophiles like me. Battery also lasts, specially at a normal volume level. I've gone for days without charging it, using it consistently. Bluetooth connectivity easily gets interrupted with walls and other objects but range is not that bad. Definitely would buy another one to add to my collection.

Addiction to the Megaboom 3 is inevitable
If you are lucky enough to turn one of these bad boys on, you will not have the will-power to turn it off. The crisp, powerful sound will leave you instantly addicted. And with an incredible battery life, it will not shut off on its own either so be prepared to lose your job and maybe even your family because you can't stop listening. Luckily, it is very portable (fits snuggly in a backpack bottle holder and has a loop to clip onto) so I find it convenient to take around the house, gym, and for recreational activities. I work out in a large gym; but with the mighty sound of this musical beauty, I can leave the speaker in the middle of the weightroom without worrying about it being too quiet. Using the Megaboom 3 made me the king of the gym and gave me my own "Iron Throne". For you bass fiends like myself, have no doubts the Megaboom 3 is everything its name indicates it is. The reverbating bass can pulse through your body like an adrenaline rush. Even at high volume, I have heard no bass distortion. What amazes me is that a speaker with amazing bass can also it all the high notes/tones just as well. The speaker pairs extremely quickly and the Megaboom mobile app can be really useful for turning the speaker on/off remotely and controlling EQ. The speaker's physical beauty from it's slick sheen puts all the IG models that you probably follow to shame. I have so far enjoyed EDM, hip-hop, pop, country, rock, and epic dramatic music with it, and all genres benefit from the amazing sound quality of the Megaboom 3. This beautiful speaker is worth the price and more. But if you are someone who has low self-esteem, go ahead, settle for a lower-priced speaker..you probably don't care about yourself or your listening experience anyways. Know that every time you turn your peasant speaker on, you'll wish you had the incredible Megaboom 3. Update: I have used this speaker for 2 years now and it still works amazingly with wonderful sound and great battery life. It is definitely a well-built machine.

Best speaker of it's kind out of 8 that I've tried.
The Megaboom 3 is a rugged, relatively waterproof speaker with great sound & ability to play fairly loud. It's not the smallest portable bluetooth out there, but it's size was still convenient enough to take along on two ski trips with me this winter. I've purchased & returned 7 different portable bluetooth outdoor speakers over the last year, & found this to be the best of the bunch..(Tried the UE Wonderboom, several Altec-Lansing models, Bose & a others that I've already forgotten the names). It's not the cheapest model out there, but I think I got my money's worth for the $200 I paid. The bluetooth range on this is far better than the speakers priced up to $100 or so. Like most bluetooth devices, you'll get some dead spots when moving it around inside & outside the house. but it's easy to work around that. The only feature I don't like is it always tells me to download the app & have internet connectivity to use all it's features. I haven't bothered to download the app, & besides that, who always has internet connectivity? Other than the annoying voice telling me to do that, & the inability to turn it off without the app, I've had no problems with it. To turn it off, I simply stop my bluetooth signal & the speaker turns off less than 5 mintues later. As to battery life, I've had it going for 6 or 7 hours at a moderate volume. Cant' say that I've had it at maximum volume for more than a couple of hours, however. All & all, this is a really GREAT speaker. It's not perfect, but what is? For me, I'm delighted I bought it & use it all the time.
