Product Features

• 4-Mic and ENC Call Noise Reduction

  Each earbud is equipped with two built-in microphones and Environmental Noise Reduction (ENC) technology. This system effectively suppresses up to 80% of background noise, intelligently enhancing your voice for clear and lossless calls. This ensures efficient communication even in noisy environments.

• Bluetooth 5.3 and Fast Auto Pairing

  Utilizing the latest Bluetooth 5.3 technology, these earbuds offer lower latency and stronger anti-interference capabilities. Audio delays are significantly reduced, and disconnections in complex environments (e.g., crowded places) are minimized. Thanks to the hall switch, the earbuds will automatically connect to your device as soon as the charging case is opened after the initial pairing.
