JumboBass™ TECHNOLOGY
EarFun's JumboBass technology is a one-of-a-kind bass boost algorithm. Developed exclusively for enhancing bass frequencies and power by integrating the customized digital signal processor and multiple dynamic range controllers.

My JBL flip got blown out bass speaker and an almost dead battery, so I did an extensive research about the available speakers.
Uboom was one of the ones which popped out everywhere. From what I gathered, I had to buy the JBL charge (around 160 EUR) to surpass what this one can do.
Used it for week or so for casual background music while cooking in the kitchen.
I would say that it is great, but possibly for the average user might be too neutral. It does not sound 'fun', but it sounds great.
I had the discount code they had for the sale and for that price and income tax-free delivery to Europe was amazing. Should've bought another one, to do a full stereo setup.
