how loud is the Onyx mini compared to a onyx studio? Like I am a basketball player and would use it for the gym. I really like the mini and want to know an opinon for it?

Asked by: ZCCCC10
Hi! The Onyx studio is louder than the Onyx mini. The mini has a fair amount of audio strength but if it is compared to the Onyx Studio, there is a huge difference in power. This is because the speaker driver on the Onyx Studio are bigger and has more range than the Onyx mini.
