This disclosure describes electronic devices with charging contacts and data transfer through magnets. As an example, augmented-reality glasses can include magnets that are flush to the frame. In another example, a virtual-reality headset may include magnets that are flush to the display portion of the headset. Various other electronic devices could also implement the magnets discussed herein. The magnets carry data lines which are effective to decrease the number of electrical contact sites on the electronic devices (e.g., on a frame of augmented-reality glasses). Additionally, a USB cable connector is provided that includes magnets that protrude on the end to achieve sufficient surface-to-surface contact by the magnets. The magnets can have a thick metal coating for high conductivity and to reduce the impact felt by the magnets when in contact with each other.
