Great sound, solid little but hefty system!
Excellent speaker system! I wanted a sound as good as an Alexa, but without the internet snoopin...errr connectivity. This speaker faithfully picks up the bluetooth from your devices and plays with rich tones--high and low. I found the white Plus and Minus a bit conspicuous so I painted them black to match the speaker. One charge on the system lasts a good deal of time..I haven't found out how long yet..on my 3rd day of use!

Audio Perfection
These speakers are friggin awesome. Got one for each of my parents for their birthdays this year. The audio is crystal clear and it also gets very loud for its size without compromising the audio quality. Great for both music and podcasts etc. Also love that you can attach a carabineer to the speaker so you can hook it onto your pants or backpack etc and have the speaker effortlessly follow you around. The different settings/features are also really cool and handy. Would definitely recommend this product and honestly any product from the Ultimate Ears speaker line as in my personal opinion this line of speakers is the best line of portable speakers I know of or have ever heard. They're priced well too. I mean they aren't super cheap but they aren't overly expensive either, it's kinda right in that sweet spot. If you've got the money and you're looking for a portable speaker, look no further than this line because the sound quality and loudness (without distortion) you really won't find anywhere else especially for these prices. I know I'm starting to sound like a UE shill at this point lol but honestly I just really do love and admire their speakers and don't think they get the credit they deserve. Anyway hope this helps!

Fantastic speaker, easy to use, good sound quality
Love this speaker. Have it in my office. Holds a long charge. Sound quality is good. I like that it powers down (or goes into standby) when it sits idle for a bit.

Great value and a fine speaker.
This speaker is a great value for the money. It has good sound and the volume can be cranked up when listening outside or in a large room with no decrease in quality. I've been looking for a speaker like this and I'm glad I found and purchased this one.

Solid sound, Easy Pairing, Great Value
Great little speaker with impressive sound for its size! The bass is solid, the audio is clear, and pairing with devices is quick and easy. I grabbed it at a Prime discount, which made it an even better deal. It’s compact, portable, and pairing it with another Wonderboom really boosts the volume and fills the house with sound. Easy 4/5 — highly recommend!

Good value for the price
I wasn’t overwhelmed by the sound, but for the price it’s totally worth it. Sounds great, easy to connect to. Not quite as much bass I would like, but it’s a small speaker. Great little speaker for the beach or the campground and if you forget it or lose it, you don’t feel too bad about it because it’s not an expensive speaker.

Powerful Mini Speaker. Great Value. Looks Great.
This speaker is quality in a greatly packaged size. The play time is superb on one charge. The design is also very aesthetically pleasing. The sound is so enormous, you would never think such boom is coming from this compact device. I recommend the WONDERBOOM 4 to anyone looking for a speaking that packs more than it suggests.

Great sound, weatherproof
Replaced our echo dot with this and could not be happier. Sound quality is excellent and it's compact, outside proof and easy to move around. Only downside is having to press a button to connect to it, but that's the trade off for using something on BT and not wifi like the dot.
