Ultimate Ears WONDERBOOM 4 Portable Bluetooth Speaker - Cobalt Blue (984-001883) is rated 4.8 out of 5 by 16.
Rated 5 out of 5 by from Best Investment Ever!!! [This review was collected as part of a promotion.] I bought this a few months ago to use for rowing training and at the Athletics track. And let me tell you right now it is one of the best investments I have ever made. Firstly, when it was first taken out on the boat it was accidentally dropped in the water. Everyone got so scared we had lost it in the river, however to our surprise, it was just bobbing along the top and still playing the music. We were all very happy!! Lastly, we took it down to the track to do our warm-up and a 10km run. The sound was great from the front of the pack to the back of the pack, even more so when the outdoor boost was turned on. Thank you so much for making such an awesome product!! My whole team is keen to test out all the other features that we have not found yet and can't wait to use it when we are at the pool without being worried.
