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 Bluetooth Speaker Under $200

Compared this to my family members who have the JBL charge 5 and the Ultimate Ears Boom & Megaboom. This has better sound quality with Oluv's equalizer settings. Does need to be upgraded to firmware 1.2.7 (link on https://www.speakerranking.com/small-medium-size/).

Amazing sound (only on fw 0.4.3)

The good:
Sound quality is the best I've heard (but only on firmware 0.4.3, apparently after that they changed the sound and it's more close to their competition, not too good and not too bad)

Build quality
Portability

The bad:
You have to manually change the firmware
The latency is not very good for movies (you can always adjust a delay but it's not plug and play)

Best audio experience of my life!

I have nothing to say other than that this box delivers the best possible sound for the price and portability, I'm using Oluv's version 0.43 and the difference between the 0.50 is huge, look for a tutorial on YouTube!
