Title: Excellant quality product, sounds terrific! Fantastic buy!
Review: 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.

Title: Exceptional Travel Speakers
Review: 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).

Title: Small but mighty speaker!
Review: The Ultimate Ears WONDERBOOM is such a great little speaker! I was impressed right out of the box. The sound quality is amazing for something so compact—rich, clear, and with surprisingly powerful bass. The 360-degree sound really fills the space, whether I’m indoors or outside.It’s also super durable and waterproof, which makes it perfect for the pool, the beach, or just hanging out in the backyard. I’ve even dropped it a couple of times, and it’s held up without a scratch. The battery life is solid, lasting through long playlists and hours of use.What I love most is how portable it is—it’s lightweight and easy to toss in a bag for trips or adventures. Plus, the pink color is so fun and stylish! If you’re looking for a speaker that’s compact, reliable, and sounds fantastic, I can’t recommend this one enough.

Title: Just has described!
Review: It’s soooo cuteee 
and my fav color too. People tryna steal it from me lol. This boom box was definitely worth it. It’s a travel size(fits perfectly in my hands), very loud (bass is really nice) and it looks exactly as shown in the photo. It was hard for me to decide how to turn it on but YouTube was helpful. The quality is top notch, it’s very strong. Fell a few times and it was nothing! Material it’s made from is just perfect (giving sturdy rubber-typed) I haven’t tested the water proof theory as yet tho but will update once I do. It connects and work well. However, I had issues connecting to a new device after pairing with another before and had to reset the box in order for it to pair with another device (YouTube helped with that too). After using it more, it doesn’t seem to have any issues pairing with new devices, hope it continues. I hope that helped!

Title: Lightweight, portable, easy to use
Review: It’s a good speaker and pairs well with another one, sound quality is decent. I feel like the sound quality could be a little better but only if you are really picky. Otherwise a great purchase

Title: Boom 
Review: This is my second wonder boom and my first lasted 8 years. Wonderful product. Use for music, audiobooks and even my white noise sleep app!! I use every day and night so a very worthwhile purchase. Plus can set by the shower and not worry about getting it wet. Highly recommend.

Title: Keep the tunes going.
Review: Our family owns three versions the boom, 2 and boom 3. They keep making them better! We probably have room for one more. I wish they linked more than 2 and I wished they linked with the other models. But totally worth it. Holds a long charge, sounds great and totally bomb proof (rugged).

Title: Powerful Sound in a Compact Package
Review: I couldn’t be happier with my Ultimate Ears WONDERBOOM Bluetooth Speakers. The set of four speakers delivers robust, immersive sound with deep bass and impressive 360-degree audio that fills any room or outdoor space.One of the standout features of these speakers is their portability. They’re lightweight, easy to carry, and, best of all, waterproof and dustproof. Whether I’m at the pool, the beach, or just at home, I know these speakers can handle it all. The fact that they float is an unexpected but fantastic bonus!The 131-foot range is another major plus. I’ve wandered all over my house and yard without losing connection, and the battery life is equally impressive, offering hours of uninterrupted playtime.The sleek black color looks stylish and modern. Overall, these speakers are a fantastic investment for anyone who loves high-quality, portable sound. Highly recommend!

Review: I planned on getting this UE WONDERBOOM 4 back in September 2024 and just recently decided to get it.I used to use a JBL Clip 3, but the sound quality wasn’t what I wanted so I decided upon this UE WONDERBOOM 4 after doing a bit of reading around.And yes, the sound quality is *much* better than my old Clip 3, especially with bass and overall clarity.And the “360 degree sound” isn’t marketing, try spinning the speaker or moving around, it’ll sound the same wherever you are.There is one small problem that you can thankfully solve on your own though…Just after getting the speaker the sound would stop every few seconds, and so I looked up how to fix it (On Android at least…)Go into your phones “About phone” section in System settings, tap “Build number” 7 times and developer mode will turn on. Then head into Developer options and make sure “Turn off A2DP hardware offload” is switched off. This will stop the audio dropouts from happening.Other than that one small issue, which take 1 star off of a 5 star rating, I’d highly recommend that you pick up this speaker if you’re looking for something small with great audio quality.And make sure to keep a look out for a sale price while you’re at it!
