WILL NOT GET BLOWN OUT (will last decades)
Ive used UE Boom products for years now and they’ve never disappointed. Every other speaker brand gets blown out, or isn’t water proof, this is the speaker for the whole family. I love taking a shower with the speaker, it makes it feel like I’m at a concert how loud it is. It’s just as loud as the Mega Boom, I have a very old version of this one, and when I bought this Boom 4, it was a seamless transition. I love how I can bring it in and out the shower to change songs and get it wet without worrying about ruining it. I’ve ruined so many phones and laptops like this over the years until I was fortunate enough to buy this speaker. It is on the pricey side, but it’s so worth it. These speakers are really loud, and I listen to music with tons of base in it, I was afraid the speaker would blow out. My sister got this model I wanna say about 5 years ago and after a month, the speaker started to sound corse like there was sand in it. I was afraid this would happen to this one, but they’ve made significant upgrades. I feel like this speaker is as loud as the old model or the Mega Boom I had if not louder. It’s a lot smaller than the Mega Boom which is nice, I thought it wouldn’t be as loud I’m very pleased. It has a portable design, it’ll fit in your cup holder, if you have big enough pockets it’ll even fit in there. I love this speaker. I bet the smaller version is even just as loud too. You can add a feature where it automatically plays your playlist if you hold down the center button without touching your phone. It only works for SoundCloud and Apple Music at the moment which is a little lame because Spotify for the win, but still cool, I bet they’re working on getting it anyway. If you’re looking for a waterproof durable speaker get this one. I believe the Mega Boom I mentioned is about 10 years old and still works like a charm. The only reason I bought a new one is so I wouldn’t had to share anymore. The color I got is adorable, the speaker is cuter in person. It connects to my phone in a matter of seconds, if you have an Apple device (I don’t know about any other devices) it makes it super easy to turn on and off your Bluetooth with this new update. Eveything is so easy. The play time lasts forever. I primarily use it in the shower, and if I don’t use it as loud, I won’t have to charge it for weeks. If I’m using it in my room for low ambience music or some white noise for my baby sleeping, it’ll last a long time as well. It does not die fast when you listen to loud music, but it speeds up the process. This will turn a week of charge into a couple of days. Either way I love the speaker, it’s amazing. Forgot to mention the new speakers don’t use the terrible android charger anymore that constantly broke inside the speaker. They switched to the type-C charger which makes things so much easier. I can use the charger for my phone, the speaker, and my baby’s sound machine. They’re all in one area, and the type C charges so fast. Just very very convenient. This is the speaker. It’s definitely worth the money and will literally last you decades. The video I attached shows how good it sounds just through my phones speakers, the video keeps glitching because I’m holding my baby lol. UE BOOM ROCKS.

Red is beautiful, but it's a soft coral, so pretty! I love UA
New Boom 4 red (coral): My Boom 3 was wonderful but was unable to take a charge after about 7 years. Just got the Boom 4 ad can't speak to issues up the road yet but it paired easily, has great sound, and looks like the same build which is terrific - I dropped the 3 many times, it fell in the bathtub ad was fine, I'm a potter and clay dust never phased it, insanely durable. Mostly reviewing early to praise the color of this one. It's actually a really lovely soft coral with a quiet pink trim and a pale blue loop. Sounds ridiculous but honestly it's the prettiest speaker I've ever seen, kind of Pottery Barn colors. I also like the big raised buttons - I listen at night and it's very easy to perform all of the stuff by feel in the dark. I'll edit this review if problems arise but I love everything UE.

Convenient and portable Bluetooth UE Boom Speaker
Enjoy using this speaker with my tablet. It allows me to walk away, even into another room, without carrying the tablet or even the phone and still listen. Just turn up the volume and you're hands free. If I go a greater distance into the kitchen I'll carry the speaker there. It will start fading in and out when I've gotten too far from the tablet or phone and I just reposition it. It's nice to hear music in the car because the quality is better than the phone when I connect the speaker to it. Very convenient and very portable.....gives a greater listening distance to what it's connected to and the audio is an improvement from the devices' speaker with nicer tones. Really like the convenience of it. Used it during the holidays. Connected it to my phone and played dinner music....guests enjoyed it and were curious how it worked. It uses a simple Bluetooth connection to pair. There is an UE Boom App that can be downloaded that will help with pairing also, if needed. I enjoy that I can move around or drive and don't need to have something in my ears to listen and it's light enough to move and sit on a table or the seat of the car. I haven't tested how water proof it is but I did spill some water on it and just wiped it off with no problems. Durable speaker and the sound is deeper and richer for something so portable. Hope you enjoy the speaker if you decide on one.

Clear, powerful sound. Fun design and easy to use. Extra app features.
As a speaker, the Boom 4 is great, nice clear, well balanced sound with decent bass. Obviously for something this size the bass is not particularly powerful but it is still adequate. I particularly like the design, the outer surface has a nice almost clothlike texture and the big bold volume buttons are fun and functional. The app adds some nice extra features like EQ and a very convenient ability to remotely turn the Boom 4 on or off. The remote power option is really nice but it doesn't always work as smoothly as I would like. I often have to try to connect with the Boom 4 in my phone settings before trying to power it on remotely but it does eventually work. Battery life is solid too, standby mode barely drains it at all. Other than that, the Boom 4 is a very enjoyable speaker with a lot of power for its size and nice, clear sound quality.

Completely Dissatisfied….
This is by far honestly probably one of the worst speakers, and worst investment into a speaker, that I’ve ever made. I understand if maybe I got a faulty speaker, maybe the internals are just not properly set up and I just can’t see it. I will say though, total waste of money. I spent $150 on a “high quality” speaker, that’s got choppy connection to the device playing music, and it has YET to last me longer than 3 1/2 hours even being charged for 8-10 hours at a time. Wouldn’t recommend to anybody honestly, again, unless my speaker is just malfunctioning. I do not like leaving bad reviews, I love to support the companies I support by buying their product, I’m just absolutely as dissatisfied as I could be in full honesty. Expected so much more. Not sure I trust to buy anything from this company at this point. Used to be good, everything collectively seems to be going downhill.

It's okay. I use a Chinese knockoff in one spot in my house and it's just as good
It's ok. A little lag on the Bluetooth between TV and speaker. Sound is ok.
