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.

Fantastic

Great sound at great volumes. Drowns out the awful music that a colleague plays at work. Tha bass response is exceptional, and fiddly music is clear as a bell. Tone is perfect. I was fully engaged once the speaker had bedded in, and i'm thinking of buying another. Setup is very easy.

Tuned by Oluv ensures an excellent sound.!

A superb recommendation, especially for this price. However, the speaker should be tuned to the latest firm update by Oluv to make it an excellent product.

Good product and service

The service process for ordering and delivery was very good and was delivered earlier than expected.
Ease of connection and sound quality are very good.
I have not put the waterproof to the test yet!
Overall good value for money and would recommend.

Fantastic sound

Out of the box this speaker sounds ok but once updated to the latest firmware (tuned by Oluv) it sounds absolutely fantastic! Really balanced and detailed sound and for a speaker of this size and price it really is outstanding. I assume later deliveries will have the latest firmware already loaded.
The speaker is well made with a satisfying weight. Couldn’t be happier with my purchase.
