Summary: The subwoofer is decent, it can get very loud and is precise and tight. That's were the Pros end. The mute button is combined with the power button. The power/mute button doesn't fully turn off the speakers, sound can continue playing when it's turned off. A weird, high pitched vibrating sound is emitted when certain mid ranged frequencies are played. The speakers crackle and pop at times Edifier support was impossible to contact when I had issues.
