päälaite
Päälaite is a generic Finnish term used to describe any device that is worn on the head or functions in close relation to the head. The word is formed from pää meaning “head” and laite meaning “device,” and its use is typically contextual, spanning fields such as safety equipment, medicine, and consumer electronics. In product documentation and technical writing, päälaite often refers to the head-worn portion of a system, with other components (like a body unit or control module) described separately.
Applications and examples of usage vary by field. In consumer technology, päälaite commonly denotes head-worn devices
Usage notes and limitations. Päälaite is a broad, somewhat generic label that can be ambiguous without context.
