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!

Great little speaker.
Really fun speaker. A breeze to set up and has great sound for its size. Good for kitchen, den, bathroom or any small area, but also versatile and works great in small outdoor areas too. Will play anything on your phone or other Bluetooth source. I may buy one or two more. Highly recommended.

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!

This Speaker Is Possessed by a Much Larger, Angrier Speaker
The Ultimate Ears WONDERBOOM 4 is built like a friendly little bean and sounds like it does CrossFit and drinks black coffee for fun. I turned it on and my house said, “Oh. We’re doing this now.” The bass showed up uninvited and started rearranging the furniture emotionally. The 360-degree sound is real. I walked in a circle around it like an idiot and the music followed me like a curse. I put it in the shower. Loud. I put it by the pool. Louder. I dropped it in the pool. It floated. Still yelling. I walked away from my phone. Then I walked farther. Then I forgot where my phone was. Music never stopped. This speaker is loyal to a fault and clearly doesn’t respect personal space. Battery lasts forever. Pairing takes half a second. Survives water, dust, and my playlist decisions. Five stars. If this thing gets any louder it’s going to start paying rent.

GREAT BUT BATTERY RECHARGING IS RIDICULOUS
Overall this thing is super. Great sound, easy to pair & use, tremendous volume & decent battery life. The one unbelievable idiotic feature is battery charging. There's no light or sound to tell you ACCURATELY how full the battery currently is. If you press a button it will say "Normal Battery Level Enjoy The Music" when the stupid thing is somewhere between 36% & 100%. Are you kidding me? 36% is barely 1/3 full & there's nothing to indicate if it's actually 40%, 57%, 84% or 100%. What kind of engineer came up with this & how did it possibly get all the way into production with no one saying, "this is the dumbest thing we've ever made". I had a rechargeable speaker for my 2nd Gen iPod in 2002 with 4 little red lights, 1 light meant 25% charged, 2 lights 50% & so on. Simple, clear & easy, didn't need to talk to tell me absolutely nothing. So now 24 years later & these rocket surgeons can't pull this off with all the advancements in tech over the last 2 decades?

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.

The Perfect gift for a Teen or golfer. Our third one! We keep giving that as gifts.
This is the third Wonderboom we have bought. We love giving them as gifts for teens. Mine goes with me everywhere. I love listening to a book while in the bath, or music outside while gardening. My husband takes it out with us on the golf course. The sound is so much better than my phone. Good base and clarity. The price is great for the quality. I rarely lose connection unless I forget what I am doing and step outside.

Bought my first Wonderboom 4 a week earlier - I was shocked such a small speaker could produce such levels of volume incl deep bass - Hats off to Logitech :0 The waterproof aspect pushed me over the edge to buy one. Turns out It's a great coffee table speaker - and packs an impressive sound footprint. The size makes it easy to place locally for any sitting-reclining situation - allows keeping the sound levels lower so that you impact others less - and yet get great bass performance. Alternately you could crank it up and be amazed or take it outside and adjust one of the 3 EQ settings to "Outdoor LOUD mode". Although default mode is better for bass. After a week of owning one I "had" to order another to get the full stereo support. It was totally worth it, and would recommend these speakers to anyone looking for a super big sound in a tiny package.
