Our take on the Ultimate Ears WONDERBOOM

The Ultimate Ears WONDERBOOM portable speaker is easy to carry — it's about the size of a softball. But this compact Bluetooth speaker kicks out powerful 360-degree sound with solid bass. And it's completely waterproof. So take it into the shower or out on the even floats! With a 100-foot Bluetooth range, you can keep your paired smartphone safe and dry away from the water.

UE WONDERBOOM portable Bluetooth speaker

The WONDERBOOM floats on the surface of the water and cranks out your tunes.

Big sound you can hold in your hand

The Ultimate Ears WONDERBOOM portable speaker is easy to carry — it's about the size of a softball. But this compact Bluetooth speaker kicks out powerful 360-degree sound with solid bass. And it's completely waterproof. So take it into the shower or out on the even floats! With a 100-foot Bluetooth range, you can keep your paired smartphone safe and dry away from the water.

Built for outdoor fun

The WONDERBOOM can be submerged down to a meter for up to 30 minutes, and still rock the party when you fish it out of the drink. The protective covering is dirt-proof, so you can use the WONDERBOOM at the beach. When it gets sandy, just wash it off with water.

Tap to play

When your smartphone or tablet isn't close by, you can use the super simple control buttons on the WONDERBOOM. Those big plus and minus signs on the side aren't decorative — they're the volume controllers. Tap the top of the BOOM 2 to play or tap twice to skip the song. It's that easy.

This thing is AWSOME. Could not believe how much sound this baby puts out. Use it on the boat, dingy and dock. It hasn't went in the drink yet, but it's nice to know that it won't sink to the bottom. If your around the water pick one up. I think you'll be happy.

Product Research


360-Degree Sound: The UE Wonderboom Bluetooth speaker is equipped with two 1.5" drivers and two 1.8125" x 2.5" passive radiators wrapped around the speaker enclosure for an immersive 360-degree sound.

Water & Drop Proof:  The Ultimate Ears Wonderboom Bluetooth speaker is IPX7 rated and has been tested to withstand up to 3.3' (1 meter) of submersion for up to 30 minutes. Make sure the weather door for the microUSB port is on securely before taking the speaker near water. The Wonderboom is drop proof tested from up to 5' and sports a hanging loop on top so it can easily attach to almost any bag, bicycle, or backpack.

Note: While the speaker is waterproof, the chemicals and salt in your pool or the ocean can damage the waterproof seals over time if not rinsed off after use. It is highly recommend that you thoroughly rinse the Wonderboom with fresh water after using it in a swimming pool or the ocean. Once clean, allow the speaker to air dry completely before charging it.

Bluetooth Audio Streaming: With built-in Bluetooth A2DP/AVRCP, you can wirelessly stream stored music and music apps from your Bluetooth source device such as a smartphone, tablet, computer, or laptop to the UE Wonderboom speaker. The Wonderboom has an extended wireless Bluetooth range of 100'. The UE Wonderboom offers music playback control and multi-device pairing with dual connection.

  • Music Playback Control: You can control the music directly from the Wonderboom speaker without picking up your smartphone, tablet, or other Bluetooth source device. Control functions included Play/Pause, Volume Up/Down, and Previous/Next Track.
  • Multi-Device Pairing & Connection: The Wonderboom can pair with up to 8 Bluetooth source devices and simultaneously connect with up to two devices. When you have two devices actively connected to the Wonderboom, you can easily switch between the two devices by simply starting the music from the second connected device and it will then become the source.
  • The UE Wonderboom does not support Bluetooth hands-free phone communication.
  • The UE Wonderboom does not support auto-reconnection.

Double Up: You can connect two Wonderboom speakers together for bigger sound. The Wonderboom cannot connect with any other speaker.

Rechargeable Battery: The Wonderboom is powered by a built-in rechargeable battery that provides up to 10 hours of music playback. To recharge the built-in battery, plug the included microUSB-to-USB cable into the Wonderboom's microUSB port located inside the weather door and into a standard USB port on your laptop or computer. You can also use an optional USB/AC power adapter (sold separately) to recharge the battery. Charging time is approximately 5.5 hours from a standard USB port and 2.8 hours from a USB/AC power adapter.

Note: The micro-USB charging cable included with the Wonderboom is not waterproof. Never charge the speaker if the micro-USB port, charging cable or connectors are wet, dirty or damaged. Always charge the speaker with a clean, dry micro-USB connector. If you think the cable or connector has been compromised in any way by water or other contaminants, do not use it to charge your speaker.

Why did you buy this?

Floats in the water and cheaper than boom 2 [ Cacimar  Jun 17, 2018 ]
Thought it might be a little more fun [ james  Jun 10, 2018 ]
Looked as good as Bose but $20 less. [ Chuck  Apr 15, 2018 ]
Great review. We are beach and pool people. [ Robert  Mar 29, 2018 ]
My older bluetooth speaker battery died. Heard this speaker playing in a co-workers office. It sounded great for such a small speaker and Crutchfield's price was good. And free shipping! [ Mark  Mar 03, 2018 ]
For playing Spotify off my Samsung cellphone. It's sound it okay but not great. I got two so I can have stereo sound. [ Gregory  Mar 02, 2018 ]

i have a wonderboom and the sound is great! [ Lynne  Dec 06, 2017 ]
Good price and reviews [ MICHAEL  Dec 06, 2017 ]
I got one in October and loved it. I decided to get another so I could sync it together and not have sound blasting from one location. Even better that it gives out sound at 360 degrees. [ Roland  Nov 23, 2017 ]
needed a good, durable bluetooth speaker to replace my old one, and this product had pretty good review's, time will tell! GAME ON!!! [ Eugene  Oct 07, 2017 ]
Own other UE products [ DAMIAN V  Oct 05, 2017 ]
I really had a difficult time between the JBL Flip 4 and this UE Wonderboom. What finally made me choose this items were 2 things. If dropped in the water, it would float and the fact that it could be dropped from 5' and still work. Great!! [ Roland  Sep 21, 2017 ]
I choose this because of the size, durability and the reviews that were posted. Most of all, I trust Crutchfield products and customer service. [ JOSEPH  Jul 27, 2017 ]
Wife listens to music out by the pool [ Rich  Jul 18, 2017 ]
Subtle color matches my Cape Cod deck. Place to configure for stereo operation. Will hang from wall mounted hooks, when in use. [ william  May 06, 2018 ]
Great reviews for a speaker this small and within my price range [ Jeffrey  Apr 13, 2018 ]
good reviews, good sale price plus using reward points makes this purchase from Crutchfield excellent. [ Darrell  Mar 26, 2018 ]
Good reviews and a good fit for a teenager! [ david  Mar 08, 2018 ]
Price, gift, reviews [ Kenneth Lloyd  Feb 25, 2018 ]
Went back and forth between this and the JBL Flip 4. Went with the UE product because it overall looks cooler, and it floats. [ Preston  Jan 05, 2018 ]
read about it in AARP [ Janis  Dec 11, 2017 ]
Heard good things about the UE brand and received an email with a $20 savings on this product. That and a good return policy, what's not to like! [ Lad  Oct 06, 2017 ]
It seems like a good speaker [ Sean  Jul 27, 2017 ]
Price and sound. [ U  Jul 04, 2017 ]
I have heard these speakers and think they sound great and wanted one. [ Ken  Jul 18, 2018 ]
Waterproof and overall reviews that I read on the UE brand. [ New User  Jun 10, 2018 ]
I was looking for a Bluetooth wireless speaker for use on the beach this upcoming summer. With the knowledge that Crutchfield products and service has always been what I expected from a company that I can trust, its a no brainer for me to make a purchase that comes highly recommended and priced so reasonable. [ Dave  Mar 02, 2018 ]
Price, gift, reviews [ Kenneth Lloyd  Feb 25, 2018 ]
I think it is really good idea [ william  Jul 30, 2017 ]
Like the size & the color [ Claudia  Jul 30, 2017 ]
This is our second Wonderboom. The first one sunk in Smith Mountain Lake (we were careless because we thought it would float), but we really liked it so I bought another one before we head to the beach. :-) [ T  Jul 04, 2017 ]
My daughter has the bigger one, and it's great... [ ej  Jun 11, 2017 ]

Loud [ ZACK  Mar 14, 2018 ]
It's pretty and matches my iphone 7 rose gold [ Elliott  Aug 09, 2017 ]
It is such a nice fashionable colour. Not too many speakers range outside the black-gray-white spectrum. [ James  Jun 09, 2017 ]
To hear music on and in the lake. [ M  Sep 03, 2018 ]
Wanted waterproof speaker for shower. [ Aaron  Jun 12, 2018 ]

5 questions already asked

Hi Robert, sorry but I never tried to use my speaker in the water. [ Christopher  May 13, 2018 ]
Don't know why mine does. [ WILSON  May 13, 2018 ]
Hi Bob, I haven't tried your exact application, but the way Bluetooth seems to work in my experience is when a Bluetooth device links up with a source, it takes over and becomes the sources only output. [ Christopher  Jan 16, 2018 ]
You could. I just don't think I would. It is still electronics. The natural elements including temperature changes and moisture are going to be harsh on it. [ RONALD G  Jul 25, 2017 ]
I haven't done so yet . The only way I would leave it is because i forgot to bring it in the house . It is small enough to carry in and out of the house so I choose to not leave it out . Besides I like to use it in the house since the sound is great compared to anything else that I have at this time . Thank you . I highly recommend this product . [ Carl  Jul 25, 2017 ]
I have left it out for a few weeks but it doesn't rain much here in palm Springs. [ Mario  Jul 25, 2017 ]
Make sure the volume is up on your phone, or whatever you are streaming with, and then + is up and - is down [ ej  Jun 23, 2017 ]
The giant plus and minus symbols on the speaker. + turns it up, - turns it down. [ DAVID  Jun 22, 2017 ]
The plus sign on the front and the minus sign below it. [ jas13  Jun 22, 2017 ]
"+"and "-" buttons on front of speaker. [ Scott  Jun 22, 2017 ]
Push the big plus button for up and the straight line for down. [ Mario  Jun 22, 2017 ]
The big + and - buttons on the front (you can see in the picture) [ Mathieu  Jun 22, 2017 ]
