Headphone OCD 耳机强迫症

Headphone OCD is a condition where you want the two earphones on a headset on the correct ears, that is, the left side is on left ear and right side is on right ear. If you put them in the wrong ears, you would feel very uneasy and would stop what your doing at hand to make them right.

Headphone OCD（耳机强迫症）指用耳机时总想着要把L一边放到左耳里，R一边放到右耳里。如果不小心放错了边儿，你就会觉得特别不舒服，然后停下手里的活儿把它们给调换过来。

The OCD refers to obsessive–compulsive disorder, which is a mental disorder where people feel the need to check things repeatedly, perform certain routines repeatedly, or have certain thoughts repeatedly. People are unable to control either the thoughts or the activities. Common activities include hand washing, counting of things, and checking to see if a door is locked.
