Big Sound, Small Package
The Ultimate Ears Wonderboom 4 is a compact bluetooth speaker you can fit in the palm of your hand, but don't let its size fool you -- this thing pumps out loud, clear 360° sound with satisfyingly thumpy bass and greats mids and highs. It's sturdy, waterproof, has a forgivingly long wireless range, and it even floats in water, making it perfect for any situation from camping trips to pool parties, or just casual listening. I like that Ultimate Ears chose a simplistic look with bold colors for these speakers, and the silicone base helps ensure that they stay put. My only gripe is that the Outdoor and Podcast EQs kind of sacrifice some clarity to push the volume in their respective directions, but the standard EQ is so rich and the speaker is so outspoken that either problem these modes attempt to solve are really non-issues, and the fact you can pair up two of these speakers for full two-channel stereo is a big plus. In addition, the regular sound signature is so clear that you can crank the volume with no noticeable distortion. I also wish you could skip back a track with the onboard controls, but doing it on your device isn't that much of a hassle. For this price range and size, I'd say the Wonderboom 4 should be your first choice for a portable bluetooth speaker.

RICH SOUND & WATERPROOF
Was looking for a portable speaker that could take being used while gardening and this is the ONE!. Bought one for my husband (black) and he tucks it into his golf bag plus one for me (hot pink so I can find it in the yard easily). Like that it is waterproof, so if I forget to bring it in and it gets wet- still works. Very rich sound even at high volume. Its a little bubble of a speaker with long battery life, light weight for how much sound it puts out. Charges quickly. Took it out of box and started using right away with no problems pairing with both of our phones. Easy instructions. Comes with a charging cord. It was on sale. Much less expensive than my Bose which I have had for several years and a better sound and longer battery life. Built like a tank. Has held up to being dropped, left outside overnight.

Excellant quality product, sounds terrific! Fantastic buy!
Works great, the sound quality is fantastic! projects exceptionally well. Has a podccast setting. The standard setting is a little heavy on the base, but I missplaced the manuel so I don't know if It can be adjusted. It turns off when not in use, its the perfect size, really like that you can hang it up. Cennnectivity is easy, stays connected all the time you don't have to keep connecting every time it turns off like cheaper speakers. The battery lasts for days, it works while charging that a bonus and they have color options. Its very well designed and made. Good value for the money, you get what you pay for this speaker is definatly worth the price, its a high quality product. You will not be dissappointed.

A very decent, sturdy speaker.
For the price I paid I am very pleased with the wonderboom. It is easy to connect and very intuitive to use. It seems sturdy and holds a charge well. The fact that it’s water and drop proof makes it great for our purposes (camping, kids, pool parties). The sound quality is good and assuming it doesn’t go to put it on me I will be recommending it to others.

The wonderboom BUMPS!!
I was looking for a smaller speaker to replace my old UE Roll 2. Based on what i read about this, and the great price on Prime Day, I can tell you this does not disappoint! For such a small speaker, this little thing BUMPS! I usually like to play some music and mostly podcasts while I work around the house. The sound is great. I am no audiophile, but this speaker certainly suits my needs. It has a minimal footprint, and it looks great—just the right amount of buttons for functionality. Although there isn't an eq via an app, that's fine with me, as I'm mostly a podcast or audiobook guy. I'm thrilled with this little speaker. I haven't tested it outside yet, it's too hot here in TX. Even if it weren't a prime day deal, I'd still buy this great little speaker, given the great sound and intuitive controls. Outstanding speaker! A++

Great speakers but one major annoyance for me
These speakers are splendid but my one ick is the loud start up and turn off sounds. They're cute but I really wish I had the option to turn it off. It's a little bit too loud for my liking and brings unnecessary attention when I want to play some music softly. Apparently the other UE speakers have the option to disable it on the app but the wonderbooms aren't compatible with the app. Sigh.Otherwise, these really are great speakers and great value for the money. I just can't use them as freely as I want to. If this isn't a non-issue for you, I think you'd be happy with them.

The best capable speaker to buy
This speaker connects to Bluetooth very quickly and the range is a great distance when staying connected. I absolutely love this speaker, first for its great volume like a really big speaker. Second the battery life for it playing is very long and I picked the perfect look and color. It’s easy to function the buttons. The capability for this Bluetooth is amazing and you won’t be disappointed.

Love it!
This is my second purchase, the first one still works great after approximately 5 years, I needed a second one for another location. The sound is great, it works well, great value, charges quickly, easy to use, and it's a convenient size.
