Product Design - Hyunsoo Choi , Jung Kim

OD is a wireless earphone with Bluetooth functionality. OD is designed to be able to wire each piece with a string to prevent users from losing the earphones when removed from ears.

A hook-and-ring set structure is applied which can also be usually seen as a fashion accessories, which breaks from the general image of electronic goods.

The design is compatible with the users’ fashion. In addition, the circular serration patterns and rings are reminiscent of the image of earrings when worn on the ears.










OD bears the appearance of an earring. The ring can be adjusted at fixed angles.






It is safe to use the earphones by linking each piece with a hooked string when doing in-door and out-door activities.






OD is designed with various colors and materials to add to the flexibility of incorporating it as a fashion accessory.



OD can be safely attached to a charger and external battery by using D-shape ring.
