I don’t know how strict the policy is for you but - i position my tablet behind my head, airplane mode, do not disturb mode, screen off. No radio waves, no light, no sound (well, technically the ultrasonic sub is a sound but it is not audible for most people.) In my opinion it creates zero distraction. However, your idea to listen while you work should work well since the listening time is so short with this generation subs.
