Can a charging case power both left and right audio arms at once?
Traditional TWS cases charge each earbud with individual spring-loaded pogo pins, which demand accurate alignment and frequently suffer from contact issues.
This glasses-charging case uses two NFC transmitters to produce two uniform magnetic fields for NFC wireless charging of the left and right temple arms. Power is delivered to both sides concurrently with no need for precise contact alignment. It relaxes assembly-tolerance requirements and minimizes bad user experience and after-sales faults caused by poor contact.
