Perfect speaker for every occasion
I absolutely love the Ultimate Ears WONDERBOOM 3 speaker, and it's become my go-to for both personal use and gift-giving over the years. I’ve purchased several of these as gifts for friends and family, and they’re always a hit! This little speaker has everything I need: great sound, portability, and durability, and I honestly can’t recommend it enough. Sound & Performance: Even though it’s small and compact, the WONDERBOOM 3 delivers impressive 360-degree sound with surprisingly deep bass. It fills up a room (or a patio) with rich, clear sound without distortion, and I’ve been blown away by the quality, especially considering its size. Whether I’m listening to music while cooking, hanging out with friends, or lounging outside, it’s the perfect speaker for any occasion. Durability & Waterproofing: One of my favorite things about the WONDERBOOM 3 is how tough it is. I keep mine in the shower to listen to music while I shower every morning, and it’s held up beautifully—definitely waterproof! The sound doesn’t get muffled by steam, and I don’t have to worry about it getting damaged by water. Plus, it's dustproof and floatable, which makes it ideal for outdoor use, whether it’s by the pool, at the beach, or on a camping trip. Connectivity & Linking: Another feature I love is how easy it is to link multiple WONDERBOOM 3 speakers together. This is perfect when you need more sound for a larger space or outdoor gathering. I’ve linked a couple of them at backyard parties, and the sound is amazing, with no delay between speakers. You can set them up in different areas and create a full surround-sound experience without any hassle. Portability: It’s also super portable—lightweight but still durable—and the fact that it’s shockproof means I don’t have to worry about it getting damaged if it gets knocked over. The 131 ft range gives me the freedom to move around the house or yard without losing connection, and it’s so easy to just grab and go when I’m heading out. Final Thoughts: The Ultimate Ears WONDERBOOM 3 has been my favorite speaker for years, and it’s one of those products I can’t stop recommending. Whether you're using it for everyday music, gifting it to a friend, or taking it on an adventure, this speaker consistently delivers top-notch performance. It's waterproof, dustproof, portable, and, most importantly, sounds fantastic. If you’re looking for a small but mighty speaker, this is the one to get!

Great low-cost speaker. Incredibly durable and waterproof.
I purchased this 2 years ago. We use it quite frequently. Still has great sound, no noticeable battery degradation. Here's the kicker: I listen to it while I'm in the hot tub. I forgot about it, added chemicals closed the cover with the Jets running on high. 30 minutes later I rescued the speaker and found that it was still working. Incredibly waterproof.

Great sound that stays charged all day
I'm a medical massage therapist in a hospital and this is one of the best portable speakers I've ever owned. The base gives a very full deep sound to the music I'm playing and stays charged all day.

Impressively durable and perfect for loud showers
I bought this speaker in 2023 specifically to use in the shower because our shower is loud and I wanted something I could actually hear over the water. It’s been great for that purpose—clear, loud enough, and totally reliable with no issues at all over the last couple of years. For context, I keep it on a suction cup holder at the far end of the tub, positioned as close to outside the shower as possible so it’s not getting direct water or steam. Occasionally the suction cup does fall, which finally led to a real stress test. Last night, the holder fell without anyone noticing, and the speaker ended up in the tub during my toddler’s bath. I walked in about 10 minutes later to find it floating in the water. I fully assumed it was done and was just relieved no one was hurt. I took it out, laid it on its side to dry, and had zero expectations it would work again. This morning, I turned it on—and it works perfectly. I honestly can’t believe how well it held up. Between the sound quality, long-term reliability, and unexpected durability, I’m extremely impressed. If you’re looking for a shower speaker that can actually be heard and seems built to survive real life, this one absolutely delivers.

Difficult to pair 2, but good once you know the trick
Purchased two of these to use in my backyard. I liked that they were small, so I could move them around easily, but that they provide outsize sound given the small form factor. Key feature for me was the ability to to pair them together. The latter part was more difficult than I anticipated. I would connect one speaker, turn on the other, which would then 'steal' the music from the first. Pushed the button on the top of both speakers at the same time, as the instructions imply. This does not work, and actually disconnects both speakers from the input device (I'm using an iPhone to play Spotify, for what it's worth) and pauses the music. No way to reconnect without turning the speakers off and then on again, which gets you back to square one. I called tech support and even they couldn't figure it out, though they did share a video which gave me the 'clue' I needed to make it work. Here's the secret: 1. Once you've paired both speakers, turn them on; one will connect to the source, one won't, as noted above. 2. Then push the middle button on the top on the speaker that is NOT playing music, until it makes the beep-boop-beep sounds. 3. Release that button, THEN press the speaker on the other speaker until it beeps and boops. 4. Music will pause, but after a few more seconds of beeps and boops you'll be reconnected and can restart the music and both speakers will play nice together. Having figured this out I'm quite happy with the purchase- 5 stars if it wasn't such a hassle and the instructions weren't so inadequate. Lots of references to the app, which isn't even compatible with the Wonderboom 3. In general the instructions and support materials leave a lot to be desired. But it's a nice product once you figure out the 'trick' and get it working.

Best bang for the buck and for outdoors sound
Buy this when on sale around 60$, probably now the permanent price that the UE wonderboom 4 has come out (reviews say the only difference ios upgrade to usb C charging from usb) as far as ultra portable speakers go, this is as good as it gets, and aging more than gracefully. After much research i settled for either this or the jbl flip 6, bought both, returned the jbl flip 6. It really depends what you want this for. If you want something for a corner in the garden for BBQ or indoors portable speaker, for the shower etc something like that, the jbl flip 6 has more powerful and better sound, but highly directional, if you want this for outdoors activity, the UE packs a punch for the size, is super portable, and the sound is much more surround sound than the jbl flip 6 which is very directional and not stereo nor surround AT ALL. When you hand the jbl flip 6 it will invariably swing around and you'll hear the sound come and go as it twists on the built in hanger. I took both on a sailing trip, and the ue boom was the best sound on an open moving ship. The rest of the crew agreed. i'd imagine it's the same in any open environment, dynamic activities or picnic etc. it's also more portable/smaller/lighter than the jbl and though both are waterproof, unlike the jbl, the ue boom floats so it's the best for water activities without a doubt. anything when you might lose it to sinking: kayaking sailing going to the beach, lake, ue wonderboom without a doubt.

Has good sound
I tried to find the flat disk shaped Ultimate Ears that I got for my husband YEARS ago because it has great sound and it still works great! Evidently they stopped making it, I don't know why. So I got this WONDERBOOM and I like it too as it has good sound as well, however I think the Ultimate ears from years ago might have a slightly better sound. Yes I would recommend this speaker.

It's small but packs a punch
As an avid traveler, I've been searching for a compact speaker that delivers impressive sound quality without sacrificing portability, and this speaker exceeds all expectations. First and foremost, the size of this speaker is perfect for travel. It's compact enough to toss into my bag or backpack without adding extra bulk or weight, making it ideal for adventures on the go. Despite its small size, the sound quality is phenomenal, with big bass and 360-degree sound that fills the room. I'm also blown away by the durability of this speaker. Its waterproof and dustproof design means I can take it virtually anywhere, from poolside parties to beach outings, without worrying about damage. Plus, the fact that it's floatable adds an extra layer of convenience for outdoor adventures. The Bluetooth connectivity is seamless and reliable, with a range of up to 131 feet, allowing me to stream music from my device with ease. I love that I can control playback and volume directly from the speaker, making it simple to adjust settings on the fly. Overall, the Ultimate Ears WONDERBOOM 3 is the perfect travel companion for music lovers. It's small but packs a punch, delivering impressive sound quality and durability in a compact package. Whether you're lounging by the pool or exploring the great outdoors, this speaker is sure to enhance your experience. Five stars all the way!

Way better paired!
These are 100% worth the price when they are on sale. They out perform the majority of other small speakers for premium sound quality, long lasting battery life, and extreme durability. These speakers really can handle drops without fear of breaking, as my toddler runs off with the grey one all the time and only real worry I have about it is getting dirty. I purchased one speaker and it was plenty loud enough for my office. It was truly remarkable how clear and loud it was at 20 - 30% volume for the size they are. A great feature that is easily overlooked is the 360 sound coverage. Where ever you place it, you’re covered, no need of moving or adjusting things around to have the speaker facing directly you. It was so good I had to purchase the second one for paired mode, and this is truly how they are meant to use these WONDERBOOM 3’s. The party mode can easily cover the large open rooms for Loud booming music and you can also switch it easily to stereo mode by holding in the middle button. Only thing I can say is if you are purchasing one at full price for a large open room, for LOUD booming music consider spending a little more and get the MegaBoom 3 or purchasing two WONDERBOOM 3 on sale.

No sirve. No la compren
No lo compren. No sirve. Se batalla para que se conecte a cualquier dispositivo. Y al conectarse se desconecta al rato. Suena muy bajo. Caro para lo que da. Sale más buena una de 5 dólares.
