As long as beQUIET simple is running, your Mac’s internal speakers are disabled.
Meanwhile, you may still listen through your headphone jack.
Simply to say, beQUIET simple only disable your internal speakers in any condition.
beQUIETsimple is designed for journalists, teachers, students, and other Mac users who would like to hear the sound but do not want to disturb others, such as in meetings, classrooms, courts, lectures, theaters, etc.
Benefiting from your Mac’s high-end hardware design, beQUIETsimple guarantees that your speakers stay quiet and your headphones working no matter if you plug or unplug your headphones (the function that PC users can never dream about!)
This App is developed due to the request of a teacher who needed his computer lab to be quiet, but still, let the students enjoy the sound with their headphones.
