Earbuds pack in a pocket and leave room for a hat, a hood or a cheek weld. They seal only if the tip fits your ear canal.

In heat, under a hood, or with a rifle stock tight to the cheek, earbuds stay out of the way. They also go under earmuffs when you need both layers, as NIOSH recommends at firing ranges.
