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. This means the bass can be enhanced while still managing to produce high-pitched vocals.

Best value for money

Clear sound and long lasting battery. There is all you need from tiny little speaker. The only cons is difficult to see buttons at low light. Thanks!

Looked at JBL, Bose and this earfun UBOOML

Was very pleasantly surprised with this speaker, my son has a Bose unit and this speaker is every bit as good sound quality wise as the Bose with a better battery and shorter charging time. Will be using this poolside next summer for sure!
