TLDR: Great speaker, absolute tank, worth it 100%I have had my two Wonderboom speakers for about five years now and these speakers just last. They have been with me through thick and thin, in no fewer than 100 different bodies of water, and through thousands of charge cycles all while remaining perfectly clear and intact. My favorite aspect of this speaker is the Bluetooth connectivity, a feature I’m sure will only improve with future generations. It is not only quick to connect, but easy to explain to others. I have dropped these speakers hundreds of times, even using one to play catch once when I was lacking a ball. The battery is awesome because I rarely remember to charge any of my devices, and I can count the times that I’ve run to 0% on one hand.As for the ... MoreTLDR: Great speaker, absolute tank, worth it 100%I have had my two Wonderboom speakers for about five years now and these speakers just last.

The Wonderboom is one of the only UE speakers without a dedicated app, and it would be nice to be able to pair with more than just one other speaker for group outdoor events. I feel like both of these would be purely software improvements, and, although I haven’t updated my firmware in a while, a firmware update would resolve these issues. Overall, 5/5 speaker, great for those who are prone to breaking electronics, such as myself, and I will be purchasing the newest model once my current speakers fail to work properly.

I absolutely love these speakers! I use them pretty much everyday. They're super light, portable, and easy to use. The price is more than worth it, especially since one of these is usually $60-$80. One is loud and clear enough, so having two is much better. My only issue is that the charging cables it comes with are very short and they're micro USBs, which makes no sense. Even the newest version uses a micro USB. I don't know why they couldn't just make these with USB-c since everything uses that nowadays. I find it kind of ridiculous that I'll have to purchase charging cables that I have literally no other use for than for these speakers. Just seems like a waste. Other than that I absolutely love them!

I’m giving this items fair because the sound quality is impressive from such a small speaker. It’s crisp and loud. The issue is because they advertise this multi speaker set up where the music plays from multiple devices. That is horrible. It constantly cuts out and skips I mean horrible. Turns out android can connect to multiple Bluetooth and that works a lot better than this buggy solution. If that feature worked I would’ve given this a 5 out of 5. Using one speaker is good though. The range you can go away from the speaker with your phone is mediocre too as well.

Best speakers I’ve purchased , im always trying different speakers since i use them for work and beat them up often, these are heavy duty forsure !!!Louder then most big box speakers and really like that you can sync 2 speakers together. Waterproof also! 3rd time ive purchased twin packs. I like to have them around home & great gift ! You wont regret purchasing these !!!! First pack i purchased are still going strong
Excellent pair of speakers. Really loud, and clear at high volumes.The bass is little heavy, and it makes the highs and mids a little muddy. The pair is too much for the shower, but really nice when outside.Super easy to pair to phone and to each other. Must pair to each other (for stereo) each time you power back on. But it's easy, so not too much inconvenience.Really portable. Can carry both in one hand, and easily fits in backpack.Great buy for the price.
I had a single speaker and was using it when doing finish work in newly finished basement room. My son started helping me and I let him pair the speaker to his phone so we could listen to his playlist. He was amazed at the quality of sound and couldn't believe it was coming from a speaker so small. He ended up stealing the speaker (ok, I gave it to him because he was so excited about it) and found this pair on sale. Gotta say that I've been wanting a second one to see how they sounded when paired together. I am very happy to say they sound great! If more than two could be connected at the same time I would definitely string together as many as I could. Highly recommend.
I have a small desk and wanted some speakers to use for it since my monitor didnt come with any built in. I nought these because they’re the perfect size and go behind the monitor on the riser. Sadly, these speakers do NOT love sharing the Bluetooth with anything else especially my trackpad… which i need to work and use the setup. Anytime i moved the mouse the speakers started fuzzing (like how it would if they were too far apart). I was able to pair the two together for Bluetooth but my god it took awhile because there wasnt enough instructions on the box, went to the link they provided and didnt see anything, and not to mention the app so many people love, yeah the wonderboom 3 don’t have an app companion…. The sound is great when working properly for what you pay ... MoreI have a small desk and wanted some speakers to use for it since my monitor didnt come with any built in.

Pleasantly thrilled by my purchase of these speakers. Was kind of a last minute emergency thing, as I had received the green light for a long distance move of 1800 miles out of my home state.Boyfriend was prepping his truck to drive the 1800 miles up to my state, pick me and my belongings up, and then drive the distance back to our new home.A day or two before the move, the sound system went out on said truck. With no option to get them fixed in time, I did some looking and found these speakers. Ordered them for curbside pickup in his town, he grabbed them, and BOY are they amazing.Lovely full sound, wide range of volume (they can get LOUD), and insanely long battery length. Charged them up before heading out, then set one on the center console or dash to ... MorePleasantly thrilled by my purchase of these speakers.

Charged them up before heading out, then set one on the center console or dash to provide tunes on the long days of driving.Note that they would sometimes fall out of his hands getting out of the truck, on quite a few occasions, so they can be tossed around with no damage whatsoever.Boyfriend got to the stop for the night, halfway through the drive, switched out the speakers to continue on the next day. Rinse and repeat for the drive back. They would last WELL through our 12 hour drive days.They worked amazingly for our situation. They will continue to provide us with tunes any time we need, whether it be working on vehicles in the garage, doing stuff outside, or hanging around in the house. Bluetooth has easy connection and a long distance connection. We’ve found they stay strong even around 60 feet away with multiple stone walls from inside the house to the garage!We love them. Highly recommended for anybody that needs a sturdy and good sounding set of speakers.
Bought this speaker in mid 2017 for ₹8,000. Average usage is more than 1 hour since then. Used by my hostelmates a lot. Waterproof feature used to listen while taking shower or gardening. Shockproof feature eliminates tension of handling it delicately. Music quality is outstanding for music, 360° feature gives amazing experience. Battery life is way better than other products of this range. Bluetooth range is around 30 feet but depends on obstruction in between. More old it gets, better sound delivered! Cons- 1- after 4 years, its top and bottom rubber got out of its place, i pasted it with feviquick, working well but now waterproof feature is not reliable. 2- difficult to clean due to net ( not a big issue though, hydrogen peroxide can clean it easily)3- amazing ... MoreBought this speaker in mid 2017 for ₹8,000.

The little WONDERBOOM puts out a pretty good amount of sound for a speaker the size of coffee mug.I'm sure audio snobs will have a problem with the amount of bass or treble, but it sounds quite good for a speaker of this size, and you can hear that sound clearly across the length of the house.The carrying loop is a nice touch, since this is a portable speaker (though it is NOT pocket-sized) and the fabric-covered frame is a tad slick. The volume-control buttons are the + and - symbols on the front, and you have to hit them pretty much directly in the center for activation. I also worry about the durability of the cover for the charging port, though this seems to be of a better design than most rubber port covers. There is also no speakerphone capability, at ... MoreThe little WONDERBOOM puts out a pretty good amount of sound for a speaker the size of coffee mug.I'm sure audio snobs will have a problem with the amount of bass or treble, but it sounds quite good for a speaker of this size, and you can hear that sound clearly across the length of the house.The carrying loop is a nice touch, since this is a portable speaker (though it is NOT pocket-sized) and the fabric-covered frame is a tad slick.

I also worry about the durability of the cover for the charging port, though this seems to be of a better design than most rubber port covers. There is also no speakerphone capability, at least not on this version.I haven't had a chance to (nor do I hope to) test water-resistance, nor drop-resistance, though apparently if floats, and the WONDERBOOM seems to be sturdier than other speakers I have tried, and according to a review from a prominent electronics website, if the fabric gets dirty, you can rinse the cover, and it should survive a five-foot drop.Did I mention, this thing is loud? It is loud enough, that while writing this review, I had to drop the volume down a good deal, as the output was painful to the ear from such a close distance. This little fella will make itself known in a big room, though I don't know if it can overpower 15-20 people in vigorous conversation.I plan to buy another to put in another corner of the living room, since these speakers apparently can pair, though without stereo effect.If you are simply looking for a loud little speaker, which really sounds pretty good, you have to give the WONDERBOOM a try. It may not have BOSE sound quality, nor the ability to pair for stereo sound, but for the price of ONE of the cheapest BOSE speakers, you can buy TWO of these. Compare them side by side (the Best Buy folks will be happy to help--take THAT Amazon), and then, make your choice. For the size, and price, and potentially 9 hours of play time, I don't think you can beat the WONDERBOOM.P.S. There is a newer model than the one I reviewed. It could perform longer and better, and pair for stereo--I don't know. I suggest you ask if those are qualities which are deal breakers.
