- WONDERBOOM 4 Portable Waterproof Speaker - Blue

Bought this speaker for my beach trip. Wasn’t worried about water or sand with this speaker. It has a very clean sound, can get pretty loud for its size. Bass is okay, but expected for speaker of this size. The build quality is great, very portable, battery lasted the entire day at the beach and night. Never had a connection problem with Bluetooth either. Overall a great speaker for the price.

Ultimate Ears Wonderboom Speaker 4 is an amazing little speaker. This is our second one (only because we lost the first). Sound quality is top notch and it’s easy to use and so portable. It’s lighter and smaller and less expensive than then the big name brand pill versions. Love the fun color choices too. We bought it because of its floating feature so we can take in on our Duffy boat. But it’s a great speaker for the pool, at the pickleball courts or just enjoying music in our backyard. Holds a charge all day.

Great speaker. I have tried several brands of these bt speakers; Tribit, Soundcore, Harmon Kardon, Bose, B&O and a few others. None compare to this for the qualities I want in a bluetooth speaker. I see it as a personal speaker for listening to music privately and for podcasts. I have a nice stereo system for serious listening, but it's not always convenient to do that. What I found was that there is a lot of sound profile manipulation by the producers of these products favoring bass output, because that's what a large portion of the buying public thinks is "good sound", with the resulting side effects on the rest of the profile.. The Wonderboom might tweak it a little, but not even close to overdone. The sound quality is really solid, including the mids and trebles. Clear and full; undistorted. Bass is solid, but balanced. Clearly present but not obnoxious. That's number one. It is light, and it is the easiest to use of the bunch. The 360 degree sound is a real plus and does fill the room. It is well protected against dust and moisture, and it floats if you drop it in the lake. It is very nicely shaped, easy to pick up, hold, carry , pack. Use it anywhere. It also has zero over compensating frills, like apps and equalizers, which are a total waste of time on something that you just want to work and not have to fuss over. This one does just that, and it has better sound quality than all the others tested, except the Luna 2 and B&O a1, but, at lower volumes it is pretty much indistinguishible.. I've sent one to my son and one to my daughter, who took it to the lake house last weekend and said it was a real hit on the dock and the boat with over a dozen people in the group, whom she said were universally complimentary. It does have two adjustments. The basic mode is "standard'. Push the button once and it gives you an "outdoor boost"; again and you get "podcast mode", which I found not to be necessary, but it does help if there is ambient noise, like, say, a shower. I also tried it in stereo with another unit and it's great. I don't really need that function, but I just might hang onto the second one and do the stereo anyway. These these little guys are affordable enough that you can get two for less than a competitive single unit will cost and you can bet that they'll sound better. Great product. Well conceived, well designed and well executed. A truly great product.

I have had mine for 5yrs and still jams. I bought this one for my daughter because she always took mine. Small and packs a lot of sound. Small to take anywhere. It always is a fast connection. Good price for the the quality.

I purchased this Speaker for $51.00 and can tell you that I've paid considerably more money for a lot less quality sound and volume. This "Wonderboom" never ceases to amaze me. It REALLY ROCKS. I've read all the reviews that say it's outdated technology, it doesn't have any App or EQ Software included and etc, etc,.....forget all that! For $51.00 I got a Waterproof Bluetooth Speaker that fits perfectly into my water bottle holder on my road bike that will loudly and clearly blast-out my Spotify Classic-Rock Playlist for up to 14 hours on 1 full battery charge. Yeah..........I'd buy it again!

This speaker is bass heavy and I don't know if I hate or loved it. Great for certain music bad for others that doesn't need the additional bass. No way to adjust bass since there are no app for this speaker. The speaker sounds great and it gets plenty loud. Pro: -Setting it up is easy. Out of the box it's in pair mode. Easy pair on the android device. -Great built quality. It is sturdy and well built. Con: -No app to fine tune sound setting -start up and power off noise is loud. No way to adjust that. What more can I say. It sounds great compared to other speakers in this category and price range. Basic, no frill, no overly complicated speaker. It gets to the point. Great speaker when it's on sale. Still great even at the non-sale price.

Great sound, travels well, long-lasting battery, and connectivity is always immediate. I’ve lost a lot of faith in Bluetooth, especially headphones, but I’m very happy with this unit.

This speaker could have been great. I still use it, but I wouldn't buy it again and wouldn't recommend it to others, for two reasons. The primary reason is the volume of the voice that speaks when the sound mode is changed. To others it may be a minor thing and not at all a dealbreaker, but it has not yet ceased to be very jarring to me. When in the shower, I use this speaker to listen to audiobooks, so every time I turn it on, I switch to "Podcast Mode". I suppose because it is waterproof, it only has sealed buttons that must be repeatedly pressed to cycle through options, rather than switches that one can "set and forget". I wish the speaker had memory for the last configuration used, because without that or toggle switches, this means that every time I turn it on I have to press the button on the bottom of the speaker twice so that it cycles to my preferred sound mode setting. Which in turn means that every. single. time. it shouts out "OUTDOOR BOOST!", "PODCAST MODE!" Because no matter how low the volume is turned down, the sound mode is completely independent and has one volume level: SHOUTING. Okay... maybe it's not truly shouting, but it's very loud and cannot be altered. As I said, it's quite jarring. The secondary reason I'd hesitate to recommend it to others is that I've noticed the sound cuts out every once in a while. This is with the paired source only a foot or two away, and I've never had the sound cut out like this with any other bluetooth speaker, so it seems like the issue is with this speaker itself. It's too bad, because if it wasn't for those two complaints, I could really love this speaker. It's waterproof, which obviously was a big selling point for me and my "I don't want to waste listening time with such mundane things like a shower" attitude. It's compact and has a small sturdy loop at the top which makes it easy to carry around and hang--you guessed it--in the shower (from a sturdy in-shower towel rack, using an S-hook). It's not a cheap lightweight speaker, so I wouldn't trust a suction-cupped device to hold it. And despite its small size, it is easily loud enough, with no distortion, to hear clearly over noisy things like the shower or running fans. I wish I could give it another half-star, because listing all these positive qualities almost makes me think three stars is not enough. But I wish the review that led me to buying this speaker had warned how loud that sound-mode announcer voice is, and with that and the sound cut-outs, I just can't give it four.

Best investment ever. Loud and waterproof

This is a great speaker. It gives out really good sound. I find if you want more bass to put it in front of a wall or something like that. Haven’t used outdoor boost mode or podcast mode yet so can’t comment on that!

Easy to hook up to this device Bluetooth wise. Great sound. I use this in a large room during a group circuit session and the volume is fantastic.

This product is good for just small room sound

Sounds amazing. Can be used as an indoor speaker as well. If you are still contemplating whether to buy this speaker or not. You can go ahead and buy it. Its worth it!!
