Ultimate Ears WONDERBOOM 4 Portable Waterproof Bluetooth Speaker with Big Bass and 360-Degree Sound, Dustproof Floating Speaker with 40 m (131ft) Range - Cobalt Blue

Amazing quality

This is one of the best sounding portable speaker available out there. Especially with the feature to connect 2 to create a stereo effect. I have already bought 3 of them.

Very bessy and loud nice speaker wonderboom love it

It's really the best if clean and clear vocals with maximum noise filtered is the priority. It has a larger bass feel so the beats are more pronounced and the volume is not very loud but pleasant to the ear. It has a sturdy build and very compact and easy to carry around. And thevwolaterproof cover is another plus. Even though price is a bit high it's worth it for the overall value it provides.

Ultimate Ears Wonderboom is class apart! I had an older version which lasted me a lifetime... Crisp sound, reliable sound, water proof, extremely portable! I personally recommend this brand and this product to everyone! It can seem pricey but trust me it's worth every penny. Ps. It's made of recycled plastic (yay!)

बहुत ही दमदार म्यूजिक स्पीकर with Ctype charging

Nice excellent, 👌

The product demonstrates excellent performance, providing exceptionally clear audio quality. While the bass response is not as pronounced as some competitors, it still delivers a satisfying impact. Utilizing a pair of these units would likely enhance the overall experience. The purchase price was 6.5k per unit, and I am pleased with the acquisition.

I’ve been using the Wonderboom 4 for a while now, and it’s one of the best compact Bluetooth speakers I’ve tried, especially for outdoor use. 🔊 Sound quality: • Surprisingly loud for its size with 360° sound • Bass is strong and punchy for a small speaker • Fills small to medium rooms easily 🔋 Battery & performance: • Up to around 14 hours of battery life, which easily lasts a full day • Stable Bluetooth connection with good range 🌊 Durability (big plus): • Fully waterproof and dustproof (IP67) • Even floats on water → perfect for pool or beach • Feels very rugged and drop-resistant 🔥 Pros: • Strong 360° sound for the size • Excellent outdoor performance (Outdoor Boost mode) • Very durable and travel-friendly • Easy to carry with built-in loop ⚠️ Cons: • No app or EQ customization • No AUX input • Not the loudest option for big parties 📌 Final thoughts: This is an excellent portable speaker for everyday use, travel, and outdoor activities. It’s not the most advanced in terms of features, but the sound quality, durability, and battery life make it one of the best choices in its size category.

My niece brought hers to a family gathering and we had it on as background music and sounded good. I was so impressed when another cheap speaker I had died I bought this one. Very happy with the sound for its cheaper price (than my JBL Charge for example which has a more superior bass but is more directional - this UE is great all round sound)

Great little unit. Works very well with good sound.

Amazing sound, easy connection, great size for kids, good battery life and water protection... So perfect for around the pool.

Bought this with the purpose of hanging it in the shower. Brilliant quality sound, even under water. Very happy.
