Abstract

A head-mounted wearable device (HMWD) may be fashioned that includes temples that pass near each ear of the user. To accommodate different head shapes and sizes, a head contact piece may be mounted to the temple. Head contact pieces with different profiles may be used to improve user comfort, aid in retaining the HMWD on the user's head, improve performance of output devices such as bone conduction speakers, and so forth.
