Tiny but mighty
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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!

Compact and good sound
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Easy to pair. Good sounds. Compact. Controls are easy to find. Mine do not come with a charging cord but I have a dozen so that was not an issue. I use this to boost my TV speakers while doing treadmill workouts. I place this in the water holder and it prevents blasting out the house.

BIg sound sMALL support
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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!

Posted .Thank you for your awesome review of the Ultimate Ears WONDERBOOM 4! We're stoked to hear it feels like a "mini concert in your pocket" and that its portability, floating design, and 14+ hour battery life are perfect for your hikes, beach days, and backyard chills. It’s great to know the compact size and clip-on feature make it such a reliable adventure buddy! We hear you on the lack of app support and EQ customization. It’s a fair point for audiophiles looking for more control. We’ll pass that feedback along to our team. Still, we’re thrilled you’re loving the punchy sound and worry-free vibe for on-the-go use. Thanks for the recommendation, and let us know how it holds up on your next outing!

Doesn’t disappoint
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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!

Finally a Prodcut that Lives Up to the Hype
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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!!

Wonderboom pair
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Already owned a single Wonderboom, when the new version went on sale, bought a pair so sync up for stereo. Sound quality is great, these are even louder than the earlier version. Good bass considering the size, long battery life, easy to operate. Highly recommended

My daily speaker
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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.

Adding to my Wonderboom 2 Sound
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased a Wonderboom 2 device (looks the same) for a few years now. I love the sound quality, the Bluetooth wireless convenience, and the longevity of the battery while using the device without it being hardwired. Since the device can be paired with a 2nd unit, and it is compatible with a Wonderboom 4, I purchased and paired the 2 devices on my laptop. The sound is absolutely amazing! It totally provides the surround sound effect, and the bass is terrific. I am very satisfied with my purchase, and I highly recommend the speaker to everyone. You will love the sound & the ability take it with you wherever you go!

VERY GREAT PRODUCT
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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!!!

Pretty good speaker!
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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!
