When functionality is no longer the first priority for users to choose products, now young people want to express their attitude and personality more and more. Retro style has gradually become a trend. Is retro appearance excellent? Therefore, I have designed this headset with reference to some classic music-related products and combined their functionality. It can cut songs and pause playback by touching the top cover, and slide to adjust the volume. Replace the top cover to match different environments and show your personality. In order to ensure that it is not touched by mistake, a corresponding mechanism is also set up for protection. Compared with other earphones, the size is indeed larger, but a thing to be displayed may not be his destination in the pocket. Those classic and useful designs should not be abandoned because of the footsteps of history. They still shine.
