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.

Great gift - good quality and price!
I purchased this Bluetooth speaker for my 12 year old grandson for Christmas. He loves it! The sound is good and size is perfect for his bedroom.

Awesome Speaker!
We have several of these and I bought this one to add to our collection. They all link together and are truly great sound! We use them both indoors and out and in all weather. Good battery life, great quality! We love them!

Great sound
This has been a very good speaker. We love the sound it produces. The volume is great. Fantastic how you can connect multiple speakers together to create surround sound in a room. The speakers connect in good unison.

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.

Quality, not very effective equalizer (mixer) in the App.
I bought one, liked it, then bought another for true stereo sound. Good sound (for me it is fine, but maybe not the very best). I am satisfied and enjoy them. Can move them around, and strong enough for filling our apartment living room. 4 stars though - when using two it can be finiky to get them both operating together. A bit of playing around that prevents me from freely using them as I don't have a lot of patience for technology. But the do connect. Also, they have an APP where you can adjust the sound (mixer for bass, treble, etc.) but not nearly as effective as I would like. But I am happy with them as they are. If you really want to equalize sound and are particular, you might want to spend more money. It is minimalist - you have to know where the control buttons are and how to use them. Could have a better instruction manual for non-tech buffs like me.

I have used a JBL Flip 5 for a few years and am still happy with it. I wanted another bluetooth speaker to use in my workshop. The sound samples from Flip 6 were good in the bass but sounded too hot in the treble for me. The Wonderboom 4 also sounds like the high end has too much sizzle for my taste. The Flip 7 sounds a lot better but is $50 more expensive than the current Boom 4 at $139 CAD. Note: The Boom 4 price has moved back up to $199. Flip 7 might be the better deal at this price point. Boom 4 seems to really shine in the clear and dynamic presentation of a natural midrange. The Boom 4 low end rolls off a bit more than the Flip 5 but retains a punchy presence. The Boom 4 really outshines the Flip 5 in its clarity and dynamics. This little speaker seems very well suited for my listening tastes of classical, jazz and other laid back styles. The UE app has battery indicator, a nice remote power on feature and a simplified EQ adjustment. It can also control playlists from Apple and apparently some others. This speaker will please people with similar tastes but probably not satisfy younger beach party listeners whose contemporary playlists appreciate the boosted bass and treble frequencies of other designs.
