Abstract
A headset apparatus having a headwear member () e.g. an ear shell, possessing a surface formation to which a separate attachment device () is reciprocally shaped to attach by a push-fit (e.g. by sliding, slotting or clipping) into engagement with the surface formation. In this way the attachment means may be fitted to the surface formation on the headwear member without requiring the use of through-holes passing through the body of the headwear member.
