Give your smartphone an audio port without sacrificing power. The RockStar USB Type-C to USB Type-C & 3.5mm Audio Adapter from Belkin is an ideal accessory for smartphones with a USB Type-C port and no headphone jack. Simply plug the RockStar into your USB Type-C port and you gain a 3.5mm audio port and a USB Type-C port. This solution lets you charge your phone while enjoying music through wired headphones, your car’s auxiliary input, and more. Belkin even built-in a DAC (digital-to-analog converter) to help improve the audio by working to eliminate static feedback.
