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.

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.

Bought my first Wonderboom 4 a week earlier – I was shocked such a small speaker could produce such levels of volume incl deep bass – Hats off to Logitech :0 The waterproof aspect pushed me over the edge to buy one. Turns out It’s a great coffee table speaker – and packs an impressive sound footprint. The size makes it easy to place locally for any sitting-reclining situation – allows keeping the sound levels lower so that you impact others less – and yet get great bass performance. Alternately you could crank it up and be amazed or take it outside and adjust one of the 3 EQ settings to “Outdoor LOUD mode”. Although default mode is better for bass. After a week of owning one I “had” to order another to get the full stereo support. It was totally worth it, and would recommend these speakers to anyone looking for a super big sound in a tiny package.

Great portable speaker ! So far, it has surpassed all the other ones I’ve tried. Very good sound with good bass for it’s compact size. It’s also waterproof and falls proof, and it floats, which is great. It seems very well made and it looks good too! Definitely my favorite speaker, I would recommend and I liked it so much I bought a second one to pair with the first one I bought. You want a solid speaker with great sound, that you can bring anywhere with you, this is it! FYI it’s been a year that I bought the first one and I use it regularly (in the shower, the car, doing the dishes…) and it still looks brand new and performs as well as day 1!

Overall this thing is super. Great sound, easy to pair & use, tremendous volume & decent battery life.
The one unbelievable idiotic feature is battery charging. There’s no light or sound to tell you ACCURATELY how full the battery currently is. If you press a button it will say “Normal Battery Level Enjoy The Music” when the stupid thing is somewhere between 36% & 100%. Are you kidding me? 36% is barely 1/3 full & there’s nothing to indicate if it’s actually 40%, 57%, 84% or 100%. What kind of engineer came up with this & how did it possibly get all the way into production with no one saying, “this is the dumbest thing we’ve ever made”.
I had a rechargeable speaker for my 2nd Gen iPod in 2002 with 4 little red lights, 1 light meant 25% charged, 2 lights 50% & so on. Simple, clear & easy, didn’t need to talk to tell me absolutely nothing. So now 24 years later & these rocket surgeons can’t pull this off with all the advancements in tech over the last 2 decades?

The media could not be loaded.
It’s easy to pack around and has pretty good sound for such a little guy. Primary uses are music and audiobooks and the sound quality good enough that I’m satisfied. It’s not Bose, but it sure ain’t bad.
I use it in the shop, out by the pool and when I’m gardening. Outdoors the sound travels a bit better if there is a wall or something solid behind the speaker. The loop makes it easy to carry or hang up and the 360⁰ sound means less fussing around with location and direction.
Connected to my Android, playing on Spotify, I can crank it all the way up with no distortion or crackling. But, I only did that this one time, so I could note it in the review. It’s pretty freaking loud.
It’s solid with a rubber cap on both the top and bottom. In case of a drop, those could be lifesavers. I’ve never tossed it in the water, so cannot attest to it’s water resistance.
It connects quickly and easily to any Bluetooth device and the buttons on top provide easy access to pairing, pause and power. It will power down if left unused for a few minutes to preserve the battery. That’s a nice function. I’m not wild about the HUGE volume controls on the front. I think they’re ugly and detract greatly from the overall appearance of the speaker.
Overall, good value for the money.

These speakers are friggin awesome. Got one for each of my parents for their birthdays this year. The audio is crystal clear and it also gets very loud for its size without compromising the audio quality. Great for both music and podcasts etc. Also love that you can attach a carabineer to the speaker so you can hook it onto your pants or backpack etc and have the speaker effortlessly follow you around. The different settings/features are also really cool and handy. Would definitely recommend this product and honestly any product from the Ultimate Ears speaker line as in my personal opinion this line of speakers is the best line of portable speakers I know of or have ever heard. They’re priced well too. I mean they aren’t super cheap but they aren’t overly expensive either, it’s kinda right in that sweet spot. If you’ve got the money and you’re looking for a portable speaker, look no further than this line because the sound quality and loudness (without distortion) you really won’t find anywhere else especially for these prices. I know I’m starting to sound like a UE shill at this point lol but honestly I just really do love and admire their speakers and don’t think they get the credit they deserve. Anyway hope this helps!

The Ultimate Ears WONDERBOOM 4 is built like a friendly little bean and sounds like it does CrossFit and drinks black coffee for fun. I turned it on and my house said, “Oh. We’re doing this now.”
The bass showed up uninvited and started rearranging the furniture emotionally. The 360-degree sound is real. I walked in a circle around it like an idiot and the music followed me like a curse. I put it in the shower. Loud. I put it by the pool. Louder. I dropped it in the pool. It floated. Still yelling.
I walked away from my phone. Then I walked farther. Then I forgot where my phone was. Music never stopped. This speaker is loyal to a fault and clearly doesn’t respect personal space.
Battery lasts forever. Pairing takes half a second. Survives water, dust, and my playlist decisions. Five stars. If this thing gets any louder it’s going to start paying rent.

L’enceinte est vraiment de bonne qualité, de même que le son. Elle est discrète et ne prend pas beaucoup de place. Le seul bémol serait le son à l’allumage qui ne peut pas se régler, donc le toudoum est vraiment fort. Aussi, il n’y a pas d’indicateur visuel de batterie. Lorsque l’on appuie sur le bouton dédié, l’enceinte nous indique si elle est chargée ou non, mais ne nous dit pas le pourcentage de la batterie. Tout est parfait en dehors de ça, la batterie tient bien !

I love this speaker! Small size makes it super portable without compromising sound quality. The added bass you get by pressing g the button at the bottom gives you great sound when watching movies. Very easy to use and set up! Lasts quite a while on a full charge! I already had one for my classroom and this is my second one for home. Definitely recommend. I bought a case for it afterwards for travelling.

For this price range and size, I’d say the Wonderboom 4 should be your first choice for a portable bluetooth speaker.

The media could not be loaded.
It’s easy to pack around and has pretty good sound for such a little guy.
Primary uses are music and audiobooks and the sound quality good enough that I’m satisfied. It’s not Bose, but it sure ain’t bad.
I use it in the shop, out by the pool and when I’m gardening. Outdoors the sound travels a bit better if there is a wall or something solid behind the speaker.
The loop makes it easy to carry or hang up and the 360⁰ sound means less fussing around with location and direction.
Connected to my Android, playing on Spotify, I can crank it all the way up with no distortion or crackling.
But, I only did that this one time, so I could note it in the review. It’s pretty freaking loud.
It’s solid with a rubber cap on both the top and bottom. In case of a drop, those could be lifesavers. I’ve never tossed it in the water, so cannot attest to it’s water resistance.
It connects quickly and easily to any Bluetooth device and the buttons on top provide easy access to pairing, pause and power. It will power down if left unused for a few minutes to preserve the battery. That’s a nice function.
I’m not wild about the HUGE volume controls on the front. I think they’re ugly and detract greatly from the overall appearance of the speaker.
Overall, good value for the money.

These speakers are friggin awesome. Got one for each of my parents for their birthdays this year. The audio is crystal clear and it also gets very loud for its size without compromising the audio quality. Great for both music and podcasts etc. Also love that you can attach a carabineer to the speaker so you can hook it onto your pants or backpack etc and have the speaker effortlessly follow you around. The different settings/features are also really cool and handy. Would definitely recommend this product and honestly any product from the Ultimate Ears speaker line as in my personal opinion this line of speakers is the best line of portable speakers I know of or have ever heard. They’re priced well too. I mean they aren’t super cheap but they aren’t overly expensive either, it’s kinda right in that sweet spot. If you’ve got the money and you’re looking for a portable speaker, look no further than this line because the sound quality and loudness (without distortion) you really won’t find anywhere else especially for these prices. I know I’m starting to sound like a UE shill at this point lol but honestly I just really do love and admire their speakers and don’t think they get the credit they deserve. Anyway hope this helps!

The Ultimate Ears WONDERBOOM 4 is built like a friendly little bean and sounds like it does CrossFit and drinks black coffee for fun. I turned it on and my house said, “Oh. We’re doing this now.”
The bass showed up uninvited and started rearranging the furniture emotionally. The 360-degree sound is real. I walked in a circle around it like an idiot and the music followed me like a curse. I put it in the shower. Loud. I put it by the pool. Louder. I dropped it in the pool. It floated. Still yelling.
I walked away from my phone. Then I walked farther. Then I forgot where my phone was. Music never stopped. This speaker is loyal to a fault and clearly doesn’t respect personal space.
Battery lasts forever. Pairing takes half a second. Survives water, dust, and my playlist decisions. Five stars. If this thing gets any louder it’s going to start paying rent.

L’enceinte est vraiment de bonne qualité, de même que le son. Elle est discrète et ne prend pas beaucoup de place. Le seul bémol serait le son à l’allumage qui ne peut pas se régler, donc le toudoum est vraiment fort. Aussi, il n’y a pas d’indicateur visuel de batterie. Lorsque l’on appuie sur le bouton dédié, l’enceinte nous indique si elle est chargée ou non, mais ne nous dit pas le pourcentage de la batterie. Tout est parfait en dehors de ça, la batterie tient bien !

I love this speaker! Small size makes it super portable without compromising sound quality. The added bass you get by pressing g the button at the bottom gives you great sound when watching movies. Very easy to use and set up! Lasts quite a while on a full charge! I already had one for my classroom and this is my second one for home. Definitely recommend. I bought a case for it afterwards for travelling.
