    The sound is good given the size and is surprisingly loud. The battery life, usb c connector, ease of use, and the water resistance with the ability to float make this a great choice. I am happy with this purchase.

    Adding to my Wonderboom 2 Sound

    I purchased a Wonderboom 2 device (looks the same) for a few years now. I love the sound quality, the Bluetooth wireless convenience, and the longevity of the battery while using the device without it being hardwired. Since the device can be paired with a 2nd unit, and it is compatible with a Wonderboom 4, I purchased and paired the 2 devices on my laptop. The sound is absolutely amazing! It totally provides the surround sound effect, and the bass is terrific. I am very satisfied with my purchase, and I highly recommend the speaker to everyone. You will love the sound & the ability take it with you wherever you go!

    Love the look and sound of this bluetooth speaker! I got two of different colors for the stereo effect. The sound is really good and they are easily transported. The range and battery life seems to be good. I rated them 4 instead of 5 because sometimes they are hard to connect to my Roku player. I have to make the attempt a couple of times in order for them to connect. Of course, that may have to do with my learning curve as I just recently purchased and started using them. Overall, they are great!

    I drive semi trucks and the stereo system in mine is unlistenable. Horrible. So I rectified the situation by getting two of these bad girls. So my review is going to be based on running a pair. They get loud and you can hear them outside the truck when it’s idling. So tackling wind/road noise was no problem. Here’s the problem. I was going to return them after the first two days because they sounded so shrill and easily distorted. I decided to give them a few more days and now that they’re broken in, they are crystal clear and natural sounding with no distortion (so long as you don’t straight up max the volume). I recommend these to all my trucker friends and honestly everybody. Just buy two and you won’t be disappointed!

    I love the UE Wonderboom. Its small and the sound is great. Battery lasts longer than expected and its easy to pair up with iphone as well. Of course, before buying you need to establish what your main use will be. It’s awesome for the patio or garage, or to use while cooking. It might not be the go to speaker for a party, though. For the price, its tough to beat.

    Really cute bluetooth speakers. I got the pink and blue one for the stereo effect. The sound is awesome and they are very convenient, especially when wanting to listen to the program in different rooms. So far, the range and battery life seems to be good. The only reason I rated them 4 instead of 5 is because sometimes they are hard to connect to my Roku player. I have to make the attempt a couple of times in order for them to connect. Of course, that may have to do with my learning curve as I just recently purchased and started using them. Overall, they are great!
