In terms of sound production both are the same no difference & beast in their class. Onyx 3 has a function where you can pair two of them via built in Bluetooth to have a stereo setup .
AVME Videos thank you very much.. another question.. is it okey if i plug the charger as long as i use this speaker.? would it damage the battery life..?
Hi , Very good question . No it would not damage the battery , if plugged in , once its fully charged the battery is designed to stand the current supply & speaker keeps running on power supply.
