    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.

    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.

    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!

    I use these speakers for work as a dance and music teacher because they’re compact, and light. Perfect for transporting around with great sound pay-off.I bought my UEBoom2 in 2018 and it is still going strong to this day, even though it’s been kicked around, but the connectivity between UEBooms means I can get 2 or more speakers going together which is great for dance classes.I bought this speaker with the view that it would have the same accessible connectivity as it’s predecessor which hasn’t been the case. I find it’ll connect to the ‘newest’ unit, and not play everything it’s needed too on these devices. I use both a Mac, and PC (as well as iPhone) for work and cannot trust this new speaker to play between Spotify/YouTube and Apple Music seamlessly. Often it just won’t play sound from browsers at all and it isn’t as easy to adjust the sound. The sound is by far superior, but the accessibility i’ve come to love with UE2 is not the same with UE3. I actively choose my original speaker if i only need to use one in all scenarios, because I can rely on it.Connecting both speakers creates an awesome sound when I teach, and because the sound quality is better on the UE3, i keep that at the back of the room to really fill the space, and keep my weedier one nearer me.Overall, great speaker, but i can’t help but comparing it and feeling it falls short.

    Having ordered various speakers and mini hi-fi systems from Think Assemble in the past, I was a bit wary that this was going to be like the others and a disappointment compared to the glowing reviews. I need not have worried, it’s an amazing little speaker.It feel solid and well made, not too heavy but in no way could be described as flimsy or plasticy, in fact it’s just right. Sound wise it’s got good bass and projects a decent wide stereo sound stage. It definately has a “front” and “back” to the sound, so if you’re “behind” it you can tell it’s not quite as good, but still far better than you’d normally expect for this size of speaker. The waterproof capability seems to work well, even though I’m not sure you’d want to try to listen to it if it was floating around in a pool as the sound is muffled by the water. But for something to listen to outside at a typical BBQ (i.e. it’s raining), or use on the beach or by a pool without worrying then it’s excellent.Bluetooth connectivity seemed reliable and battery life was very good.Only thing I wasn’t so keen on was that the connect/disconnect/power off/on beep from the speaker is a bit loud if you’re somewhere quiet (e.g. camp site late at night) but that’s about it.Overall a great little speaker and worth every penny.

    UE3 & iPad The Perfect Match
    The UE3 is a fantastic speaker that is a go anywhere product and is easily synced with the iPad! As long as I have a cell connection or a WiFi link I’m wired for quality sound. It’s worth the money!
