I have a pair of Boom 2’s, several years old, that I’ve been using in the shower and also for travel. After about 8 years, the batteries are getting old, and the speakers are also a little bit heavy for travel. After reading the review on Rtings.com, and seeing the great Black Friday pricing, I’ve ordered a pair of these.
I’m happy to report they sound essentially equivalent to the Boom 2. If there’s less bass, it’s mostly imperceptible. The battery life is better even than the brand-new Boom 2. They’re smaller and lighter to carry, they pair more easily, they can be put in stereo mode without using an app, and they’re plenty loud enough for the shower, a hotel room, or for background music when the family gathers at an AirBnB.
The overall sound quality is very good. No deep bass, of course, but enough so the music sounds balanced, and male voices on podcasts sound natural. Highs are extended enough for natural-sounding cymbals and strings, and the sound is clean and not distorted if the speakers aren’t pushed.
And exceptional travel speaker, even if you need two (and nothing beats stereo when you can separate the speakers properly).

Was looking for a portable speaker that could take being used while gardening and this is the ONE!. Bought one for my husband (black) and he tucks it into his golf bag plus one for me (hot pink so I can find it in the yard easily). Like that it is waterproof, so if I forget to bring it in and it gets wet- still works. Very rich sound even at high volume. Its a little bubble of a speaker with long battery life, light weight for how much sound it puts out. Charges quickly. Took it out of box and started using right away with no problems pairing with both of our phones. Easy instructions. Comes with a charging cord. It was on sale. Much less expensive than my Bose which I have had for several years and a better sound and longer battery life. Built like a tank. Has held up to being dropped, left outside overnight.

The Ultimate Ears Wonderboom 4 is a compact bluetooth speaker you can fit in the palm of your hand, but don’t let its size fool you — this thing pumps out loud, clear 360° sound with satisfyingly thumpy bass and greats mids and highs. It’s sturdy, waterproof, has a forgivingly long wireless range, and it even floats in water, making it perfect for any situation from camping trips to pool parties, or just casual listening. I like that Ultimate Ears chose a simplistic look with bold colors for these speakers, and the silicone base helps ensure that they stay put. My only gripe is that the Outdoor and Podcast EQs kind of sacrifice some clarity to push the volume in their respective directions, but the standard EQ is so rich and the speaker is so outspoken that either problem these modes attempt to solve are really non-issues, and the fact you can pair up two of these speakers for full two-channel stereo is a big plus. In addition, the regular sound signature is so clear that you can crank the volume with no noticeable distortion. I also wish you could skip back a track with the onboard controls, but doing it on your device isn’t that much of a hassle. For this price range and size, I’d say the Wonderboom 4 should be your first choice for a portable bluetooth speaker.

These speakers are splendid but my one ick is the loud start up and turn off sounds. They’re cute but I really wish I had the option to turn it off. It’s a little bit too loud for my liking and brings unnecessary attention when I want to play some music softly. Apparently the other UE speakers have the option to disable it on the app but the wonderbooms aren’t compatible with the app. Sigh. Otherwise, these really are great speakers and great value for the money. I just can’t use them as freely as I want to. If this isn’t a non-issue for you, I think you’d be happy with them.

Great sound where you don’t expect it from such a device. Stable and fast bluetooth connectivity, very portable.
Also bought another one as a present, happy owner as well.

For the price I paid I am very pleased with the wonderboom. It is easy to connect and very intuitive to use. It seems sturdy and holds a charge well. The fact that it’s water and drop proof makes it great for our purposes (camping, kids, pool parties). The sound quality is good and assuming it doesn’t go to put it on me I will be recommending it to others.

Man, this speaker packs a punch! The Wonderboom 4 blew me away with how much bass and volume it puts out for such a small device. It has three sound modes—Standard (deep bass and loud), Outdoor (boosted volume, less bass), and Podcast (voice clarity)—and each one does its job well. I mostly kept it on Standard for that rich sound.
I bought it mainly for kayaking since it’s advertised as waterproof and floatable—and it delivered. Had it playing for 5–6 hours, and it easily filled the area around my kayak (about 130 feet) with solid sound. Toward the end of the trip, I actually flipped my kayak and the speaker got fully submerged. Pulled it out, let it charge back up, and it still works perfectly. I did grab the extended warranty just to be safe, but honestly, it’s built tough.
Only regret? Not buying a second one so I could pair them. This thing is a beast for the size.

Works great, the sound quality is fantastic! projects exceptionally well. Has a podccast setting. The standard setting is a little heavy on the base, but I missplaced the manuel so I don’t know if It can be adjusted. It turns off when not in use, its the perfect size, really like that you can hang it up. Cennnectivity is easy, stays connected all the time you don’t have to keep connecting every time it turns off like cheaper speakers. The battery lasts for days, it works while charging that a bonus and they have color options. Its very well designed and made. Good value for the money, you get what you pay for this speaker is definatly worth the price, its a high quality product. You will not be dissappointed.
