Customer Ratings & Reviews

I absolutely love this portable speaker! It’s great and easy to travel with, it doesn’t take up space and the battery life is perfect on it. I have a 1B1B apartment and the sound fills up the entire space. I also use the speaker at the pool and beach it gives plenty of sound and bass!! It also comes with a charger so you don’t have to purchase one. Best purchase ever!

Ultimate Ears Wonderboom 4 just blows me away every time I take it out—it's like having a mini concert in your pocket! The portability is next level; at just 0.9 pounds and super compact, it clips right onto your backpack or fits in a cup holder, perfect for hikes, beach days, or just chilling in the yard. I love how it floats also. Battery lasts forever too—easily 14+ hours on a charge, which is a game-changer for all-day adventures. That said, it's a bummer there's no app support at all; you can't tweak the EQ beyond the basic Outdoor Boost or new Podcast mode, which means you're stuck with the out-of-the-box sound if you want more customization. It's punchy with decent bass for its size, but without app tweaks, it might not hit the sweet spot for audiophiles. Still, for quick, worry-free sound on the go, it's a total winner—highly recommend if you're not chasing fancy controls!

It’s super portable, battery lasts, and it says it’s waterproof. I haven’t tried submersion, but it’s been splashed a little, hahah. At this price point, it sounds great. No regrets.

It’s compact, it has pretty decent sound, and I can take it in the shower rather than taking my phone in. I really like it, and I love the color. It lasted a long time on one charge, which I really like, so overall I am really pleased.

Wonderboom has roughed it out with me during work. Working long hours outside as a carpenter and also doing landscaping I like to have some music going. The Wonderboom lasts for hours and with it being waterproof you can’t go wrong. It’s a plus if you work manual labor! The sound packs a good punch too!

My second portable speaker and my last. This thing has amazing sound. 12-14 hour battery life, portable and waterproof. Don't know what else I could ask for.

This speaker is great for on the go and for personal music. Even though it’s small, this speaker can get loud. Sound is very clear, and the optional mode are a great tool, depending on where and what you’re listening to. Battery is on power to what is advertised and maybe more.

Super happy with a pair of these for the smaller rooms of my condo. Nice sound, which is the main thing. I mostly play popular music, podcasts, and cast Youtube or video streaming. No latency issue. Easy to use and pair. Attractive and easy to move from room to room. Really good battery life.

Love the size and portability. Sound is good and no problems with battery life.

We looked at several BT speakers under $120. Wonderboom 4 was the best of the lot for excellent sound, easy user interface and setup, easy to parallel units or go stereo for even better sound, rugged and waterproof for beach or boat. Others may have had a little better sound, but they were not suitable for outdoors or boat, nor had simple interface for setup and sound quality. We bought two of these - use with iPhone, and MacBook. Love them.

I love this speaker. I like that is produces a huge amount of sound with clarity and lasts a long time. The best part ia that it's compact and takes up minimal space, which also allows you to travel various places with it,i.e., work, outdoors, social gatherings, etc. Another great feature is when in large open spaces you can utilize the outdoor amplified booster fearure. I couldn’t be more happy with my purchase!!

Very good quality speaker , I use it all day at home and work i enjoy the portability easy connection, good sound quality . I have a clip 4 to compare it and i think that the bass in this speaker is slightly better . The only thing that i would knock on is the noises it makes when you turn it on and off its a little much but i guess you can get used to it . I was able to link it with another wonderboom which creates a nicer setup and sound . Overall i think is a worth it speaker.

Very good quality and the sound is amazing! There is also an outdoor setting for optimal sound without the bass that sounds amazing as well!! You can also sync 2 together for playing on dual speakers!!! Very great for the price! I use it everyday, on full blast most days and I get through a full work day without having to charge. It's also waterproof for outdoor adventures etc and won't break if you drop it! Very great product that they've almost perfected this time around especially with the USB C port !!! I HIGHLY recommend!!!

The sound is good given the size and is surprisingly loud. The battery life, usb c connector, ease of use, and the water resistance with the ability to float make this a great choice. I am happy with this purchase.

Pretty decent speaker! I was torn between this one and the next step up but that was twice the money. Glad I held out. I work in a loud machine shop and this little guy has no problem being heard. Plus it's resistant to basically everything. I can run it for 3 days before charging too. Good speaker!

Bought this speaker as a gift for my dad’s birthday, and he was absolutely happy with it! Worth the upgrade from an old sony speaker he decided to give me instead. Would def recommend if looking for a long lasting speaker with loud surround sound!

Wonderboom, easy to connect, clean sound even with high volume. Great portable speaker

Very happy with the purchase. Don't let this small speaker fool you- it's powerful, sounds great, and the fact that it's water and dustproof just makes it so versatile. The Bluetooth connectivity is easy and quick. My only minor complaint is the price being higher than other options, but in my opinion, it's well worth it.

Great sound. Portable. Good battery. Love the design.

Boom speaker best portable speaker I can take it anywhere and where I want fits perfectly in the palm of your hand speaker features good battery life works amazing indoors and outdoors performs better than more expensive speakers
