Review: Great for the Beach! - 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.
Review: Wonderboom speaker - 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.

### ⭐⭐⭐⭐⭐ Definitely in the "You Can't Go Wrong With It" category.
*by R***M on August 13, 2026*

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.
