Ultimate Ears WONDERBOOM
Crutchfield Customer Review (What's this?)
Great sound and my wife loves the color.
Pros: Surprisingly good sound quality in a small package
The WONDERBOOM floats on the surface of the water and cranks out your tunes.
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 lake...it even floats! With a 100-foot Bluetooth range, you can keep your paired smartphone safe and dry away from the water.
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.
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.
Great sound and my wife loves the color.

Average Customer Review(s):
Great sound and my wife loves the color.
Pros: Surprisingly good sound quality in a small package
Works great and surprisingly loud for its small size!
Great sound from a device just slightly larger than a coffee mug. Very easy to use and pair up with your devices.
Love it. Sounds great.
Great speaker! Easy to get set up and use. Great sound for my audiobooks.
Outstanding sound quality from such a small device. Lacking in deep bass but what do you expect. Clarity of sound great, no muddiness at all. Does not overextend itself trying to reproduce frequencies it has no right to attempt.
These are great. They are highly portable, and sound especially good when you pair two for stereo sound from your Bluetooth source. I use them when out on the deck, working in the yard, or working in the garage. In fact I keep inventing ways to use them.
Pros: These are solid.
Cons: They have very good battery life. It's always a bummer to need to plug them in because I didn't start the day with a fresh charge. (Operator error.)
Wonderful little speaker one can use anywhere and not have to worry. Great sound quality from rich highs to solid bass. Various color options allow this speaker to blend with the environment or add some splash.
Pros: Small, portable, great sounding bass.
Cons: None at this time.
Quality built speaker. Big sound from a small speaker. Especially the bass. A little on the expensive side though.
Pros: Great sound. Good bass from such a small speaker
Cons: Expensive buy on sale
I did not want to believe that this little thing can do such a great quality of sound!!
great little speaker that you can take anywhere. add a carabiner and you can easily clip it to your bag.
Pros: small, convenient, good sound quality, battery life, waterproof (though we haven't tested that yet!)
Cons: none really
Excellent product , I will recomend it.
Pros: Excellent sound, water proof
Rugged, but has its negatives. Good sound, misses some mids. No battery gauge like some provide. Instructions are minimal. Long time for a complete charge. Skip/pause button can be finicky. Paring two together is only linking, not stereo, why UE? Good sound, but not at full price. I bought mine on cyber Monday. Buy it on sale and it's ok, by itself. If you want stereo with two, it won't happen.
Pros: Good sound Size Portable
Cons: No battery gauge No stereo pairing of two Pause/skip button can be tough to activate
I love my little Wonderboom! Toss it in my luggage for local and international trips -- it's great to be able to listen to music or the radio without having to always use headphones. The sound quality is really nice. Yes, it starts to distort as the volume increases and more complicated music can confuse it. But that's only to be expected for such a tiny unit. For pop, rock and jazz, it's pretty great. Charge lasts a long time. A terrific gift for the student or road warrior in your life.
Good sound quality for the size! The size, shape and construction made these speaker very appealing to me for use in a camper van. The internal lithium ion battery using a USB mirco cable for recharging is easy since I have numerous other devices using the same cable. The packaging is simple but rugged with the minimal instruction printed inside. However, there was no information on how to pair two Wonderbooms together, even though UE highlights that feature in their sales pitch. I had to call Crutchfield's excellent and very helpful tech support (Chris) to find out that there is another button under their logo to pair the two speakers.
Pros: Size, build, sound quality.
Cons: No instruction included for pairing with other Wonderboom speakers.
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.
Pros: Great sound, waterproof and floats.
Cons: None so far.
It doesn't float It does sink to the bottom of the lake if placed on water.
Pros: Pretty loud for a small speaker
Cons: Sink to bottom of lake if placed on water
Awesome sound for its size. Very rough and tumble just throw it in the bag and go. Perfect for the beach or the boat
Small package big sound. Use on my boat and they rock when both are synced together.
Great sound for this small speaker. I could not believe the sound that comes out of this;it's so clear. I have no regrets in purchasing two of them.
Pros: Portable yet powerful speakers. The sound reproduction is simply great nay awesom. I highly recommend it.
Muy buen sonido para el tamaño, buen material de construcción, excelente
Arrived on time and in perfect condition. Very easy to sync to my iPhone (Bluetooth). Fantastic sound!! Take it with me in the afternoons when the weather is warm and sit by my garden. I love it!!!
Pros: It syncs easily to Bluetooth. Fantastic sound. Lightweight and easily portable. Can change volume without touching my phone. Would make a great gift.
Cons: There are absolutely NO cons with this item.
An excellent product. It is a lot louder than it looks and the battery lasts a long time!
Pros: It's loud, it sounds good, and the price is right.
Cons: None that I've found so far.
Overall this unit is pretty good. I Purchased two of them to get more of a stereo feel for my back patio. Crisp clean sound and they have a decent higher volume distortion threshold. My only minor gripe would be that they're not quite as "Bassy" as I thought they would be. Especially with a name like WONDERBOOM. I have a cheap $25 Bluetooth speaker that seems to put out a bit more bass. That being said, I'm happy with the purchase. Neat design, easy to use, and easily transportable. Would recommend.
Pros: Clean sound Good design Portable
Cons: Not quite enough bass
bought this for the wife for her office. she loves it and also brings it home and listens to it while she is washing her car and working out in the yard.
Pros: great sound from a small package
Cons: none as of yet
After two week's use paired with an iPhone 5s I found the sound very satisfying. I found heavy thumb pressure was required on switches for pairing and other functions.
I was pleasantly surprised that the reviews I read about this speaker were utterly correct. It's a great little speaker that has some weight and has a great sound for it's size. Most impressed with it's bass tones. Thanks Crutchfield you guys came through again with offering a great product at a very respectable sale price.
Great sound! Great service from Crutchfield as expected!
Great sound (at a reasonable price) packed in a tough, portable, water resistant unit that takes input from bluetooth sources. Pretty cool! Be sure to buy plug for faster charging!
Pros: good sound, good look, portable, waterproof/resistant, reasonable price, easy setup, strong Crutchfield support
Cons: for this price and functionality there are no cons.
Great BT speaker and even better price from Crutchfield. Early use is has been great. Awesome sound from a small package. I have not gotten it wet as of yet, so have to wait to see how it holds up.
Bought for my daughter. She loves it! Good sound.
Great sound! Love this speaker! I've had some other cheaper Bluetooth speakers and the sound quality doesn't compare. Great product!
Pros: Good, loud sound Waterproof Long battery
Cons: Can't think of any....
Couldn't be happier with the product performance combined with the reasonable price. Thankful that Crutchfield was able to provide all the "how to" info that the manufacturer apparently felt was unnecessary. My tech skills are limited to which end of the wheelbarrow do I need.
I bought this for my son. He absolutely loves it. Excellent speaker.
Easy to use. Got one for Christmas and bought another in January. Instructions on how to pair were sketchy. Looked at an online video site and found the pairing button is in the center of the top. They sound great outside with Accu Radio app.
Pros: Easy to use. Good sound. Long battery charge.
Cons: Sketchy instructions.
Amazing the sound of UE wander Boom produce, for the price of it and as good of higher price brand
The UE Wonderboom is definitely an upgrade over my previous bluetooth speaker. The bass is great for its size and the fact that it is water resistant is awesome. I can not wait until it is used by the pools this summer
Pros: Sound Quality Bass Portability Durability
Cons: Not USB-C No charging unit for the cord
big sound, little package!
This speaker has fantastic sound for its small size. If anything bad should happen to this speaker I will purchase another identical one.
Great sound for a little package and Daughter can rock out in the shower!
Purchased as a gift for a co-worker. Size is perfect to tote around. Paired on first try. Truly awesome sound for a unit this size.
Just gave it to my daughter for Christmas. Solidly built and water safe. The sound quality is good and comparable with as others within the same price point. Sharp and attractive, portable and good battery play time per charge makes this a strong product for those that want an affordable and fun speaker to take with you are keep it at home.
Pros: Portable Good bass response and decent high end Simple and functional and a great price
Great sound from such a small unit! Love it!
Pros: Awesome sound, very portable.
my wonderboom is awesome, I'm outside a lot and it comes in very handy, no cord to get in the way and it has great sound!!!
This small "take along" waterproof speaker puts out a vibrant and amazing sound for a small speaker; great product at a reasonable price. Highly recommend.
Pros: compact, great sound
Works and functions as advertised
Pros: Water proof and links to cell phone
Great product. I highly recommend buying two of them as you can link them up.
Great sound, price and size!
Pros: Sound quality Size Waterproof
Very good sound out of such a small unit and very easy to pair with a cell phone.
Pros: Good sound, small, light and easy to pair with a phone/Bluetooth device.
Great speaker for the cost. Used it on a 3 day camping trip and it held charge great and had no problem handling the rough and wet conditions.
Pros: Small, waterproof, and doesnt weigh too much.
Cons: Battery life degrades a little quicker at full volume but that is to be expected.
This little speaker is impressive. The sound it puts out is astonishing for its compact size. It puts out sound in all directions, making it useful in so many situations - home or travel. I'm so pleased I bought this - it is just the right portable speaker.
Pros: Sound quality, size, ease of use, durability
Good things come in small packages. I would have given it a 5 but for the lack of instructions. You have to google the product to get a manual. And yet the inside material doesn't even tell you that. Sound is a little muffled sounding, but bang for the buck, you can't beat it. Haven't tried throwing it into a bucket of water to try out its waterproof rating. Buy it!
Pros: Value Sound Power Ease of use
Cons: Lack of instructions and where to get it.
I bought this product for use while on vacation. For its size, the WONDERBOOM puts out a very nice and full sound with a solid amount of bass. For use at the beach or in a cabin or even at the office, this unit is ideal, especially given its compact size. I also found the battery life to be as advertised.
Pros: Sound quality and size
Good sound! Cannot get the app to work. It wants me to connect to my phone to start app. It is connected to my phone app will not start.
Pros: good sound
Cons: App doesn't work
Es uno de los mejores que he comprado y lo mejor es contra el agua flota en tu alberca tiene un sonido bastante decente y el estilo es lo mejor yo recomendaría comprar otro
Pros: El precio es muy bueno y el sonido es muy bueno
Cons: No le encuentro nada malo por el momento
These speakers are excellent. They have a big sound for a small speaker. There are two minor things that could be better. The pairing button is very well hidden under the UE logo on top of the speaker and at first I tried pairing them by pressing the Bluetooth button instead and that was a little frustrating. The other very minor issue is the loop for carrying or hanging is too small for any real useful purpose. I do like these speakers and would very much recommend them.
Pros: Great sound for the size.
Cons: Pairing button is very well hidden.
Great sound in a small package! Very easy to sync! Extremely happy with this purchase, may pick up a second one for a family member!
Pros: Great sound. Easy to Sync. Great portable device. Long lasting battery
Cons: None so far!
I have bought several portable Bluetooth speakers in the past and I would say this one is the best! Crutchfield is the most knowledgeable company I have ever bought thru. Lee
very cute and well designed. rough and loud poor sound quality no instructions manual charger provided incomplete too expensive
Pros: cuteness roughness loudness
Cons: poor sound quality poor bass inability to create stereo sound whe. placing a second speaker too expensive
This small speaker has excellent clarity and bass. I bought two of them for my daughter and son. They loved the speakers! They also like the fact that they could use them around the pool, beach, etc. In addition, we found out that both speakers could be linked from one source so you could have two speakers running for more sound. Simple to use and it took only 30 seconds to set up the speaker. I would recommend the UE Wonderboom to all who want good sound for a great price.
Pros: Compact, waterproof, shock resistant, ease of operation and great sound.
Great sound for the price. Easy to use once you know what to do. I use it for golf and any other outdoor activities. Should have bought 2. Crutchfield is my go to for all electronics. Great communication and quick delivery. Too easy! Plus I got mine on flash price sale........
Pros: Price, ease of use, rugged
Excellent sound and long time of use without having to recharge this mark UE is of the best in the market In terms of best price, sound quality, durability in time of use
Pros: Portability, long life, waterproof
Cons: not any
Very good for its price. Surprisingly loud for its size, but the mids are not very clear.
Pros: good sound quality good base
Cons: mids are not very clear
Fantastic !!!!! Very pleased with performance . The sound awesome , the amount of bluetooth items that can hook up to the wonder boom is great . I believe it is 8 phones or iPads to whatever will match up . Thank you for the expedient delivery . In other words very satisfied .
Pros: All good in every aspect of item

Good sound and nice volume. Very durable.
Pros: Compact size, waterproof
Cons: Charges with a micro USB, raspy sound when played really loud
good sound for their size & price point, which is the main thing... would've given it 5 stars if the instructions for pairing multiple speakers weren't so cryptic. why no mention of the button beneath the logo? at least they have customer service reps...
Pros: good sound, surprising bass response & volume for the size
Cons: needs better instructions for pairing multiple speakers

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.
- 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.

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 ]

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 ]
