Foldable headphones

Foldable

— the ability to compactly fold the headphones during non-working hours. This feature greatly simplifies storage and transportation: folded headphones take up a minimum of space and can often fit even in a pocket, and the likelihood of damage is minimized.

Note that almost all folding models are overhead — regular or full-size (see "Design"); in-ear "ears" and liners are quite tiny in themselves, they usually do not need to provide a special folding design.
