Abstract: Items such as enclosures may be provided with hidden magnets. An enclosure may be formed from a flexible housing layer. The flexible housing layer may be configured to open and close by folding around fold axes. Portions of the flexible layer may include a flexible base layer with openings. Flexible magnets may be embedded within the openings. The flexible magnets may be used in forming a magnetic clasp for the enclosure. The flexible magnets may each have a height and durometer value that closely matches the height and durometer value of an adjacent portion of the flexible base layer, thereby helping to hide the flexible magnets within the housing layer.

Abstract: A wearable device includes a support and a cushion that is coupled to the support, the cushion including a first portion and a second portion, the first portion having a first stiffness, the second portion having a second stiffness, and the first stiffness is at least four times greater than the second stiffness.

Abstract: A head-mounted device may have a head-mounted housing containing rear-facing displays that display images for a user when the head-mounted housing is worn by the user. The head-mounted device may have an adjustable-tension headband coupled between first and second sides of the head-mounted housing. The adjustable-tension headband may be operable in a stretch fabric tensioned mode in which tension for the headband is provided by stretching a length of stretchable fabric in the headband and may be operable in a cable-tensioned mode in which tension for the headband is applied by a tensioned cable. A knob or other adjustable cable tensioning mechanism may be used to adjust cable tension.

Abstract: An electronic device such as a pair of headphones may be configured to be worn on a head of a user. The headphones may have a headband and earcups that are coupled to the headband. The headband may have a frame and a headband frame cover that is removably attached to the frame. The cover may have protrusions, may be inflated using a pump, may include a battery and other components, and may include sensors. An earcup movement synchronization mechanism may be used to synchronize movement of a left earcup with a right earcup. A torsion spring with a stop mechanisms or other bend limiter may be configured to prevent overbending of the headband.
