Review: GREAT SPEAKER - I ordered this speaker before I went away on holiday. First impressions are very good. I have had a lot of Bluetooth speakers, even though this isn’t the best for sound quality I have heard, this is the best for price. Don’t get me wrong this speaker sounds great for its size, vocals are crystal clear base is okay but could be better. But then you also have to look at the many other things this speaker has, like waterproof, drop proof and good battery life. If you want a speaker that has great sound quality for its size, something you can chuck around and dump in a pool this is definitely the speaker. All throughout the holiday this speaker was being chucked in bags, thrown around a pool, floating in the pool, continuously being submerged battered and Beaton and it’s come back looking as good as the day I purchased it. The only thing that’s a minor disappointment is the base, some songs it’s there, others you can hear it struggle and it lacks the thumping of the ground. But I love my base so I don’t think this would affect many people as the speaker sounds great anyway. Truly the most compact, tank of a speaker I have had. I’m in love with it, and I will be staying with UE for a while. Not to mention the app that comes with it, where you can pair many more speakers together. Let other people connect at the same time so you can all play music together. Turn the speaker on and off when it’s in your bag, adjust the EQ settings and so much more, honestly all the features of this speaker out weighs the small lack of base.
Review: The money paid is worth it - Probably the best speaker I’ve bought, I’m glad I listened to online reviews. It can go super loud and the sound quality is great, I’m afraid to let it loose on full volume as I’d definitely mess with my neighbours. Battery life is good so far, I’ve only charged it once since I’ve had it and with light use the battery is slowly going down. The feature to turn it on remotely is a great feature.

### ⭐⭐⭐⭐⭐ Excellent
*by S***. on 5 April 2025*

Sound quality didn't seem great out of the box for me, but that was quickly solved through the equaliser in the app and now it sounds fab. It's also very loud! Love that you can switch the speaker on and off from the app, and that it can store playlist that you can choose via the "magic button" at the top of the speaker. Battery life so far is great - I've used it for a few hours a day the past week and have only needed to charge it twice. All in all a great speaker and definitely recommend!
