cue teenagers with "hearing problems" so they must wear the pods during classes in 3 .. 2 ..
Is it that teenagers sometimes have hearing issues? That's definitely true; many people are born Deaf or with hearing impairments. Some people get injured.
Is it that teenagers might fake having hearing issues in order to wear pods? Either they will be paying attention in class or they won't; this will be obvious from their grades shortly.
You can ignore lectures, not participate in teacher-led activities, generally be a nuisance, and still get an A such that your parents would never catch on to you.
