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.
Enjoy deep, punchy bass sound with EarFun innovative JumboBass™ technology UBOOM L speaker. Dual passive radiators work together with the 55mm dynamic bass booster speakers to enhance low-end tones, giving a clearly punchy bass sonic experience.
The layout of the side passive radiators has been optimized to reproduce clear bass sound.
Pair two UBOOM L speakers together for stereo and bigger sound, so everyone dances to the same beat.
With an IP67 rating, your speaker is waterproof and salt-water-resistant -- so you've no worries using it by the sea or the pool -- and there's no problem washing it either. Plus, it floats too. So if you drop it in the pool, it will pop to the surface in seconds–ready to rage.
The speakerphone function offers a convenient way to talk hands-free, whether it's a conference call for work or a chat with friends.
