These are ear-cuff type earphones. They didn't fit my ears, so I stored them in a dark place with little use. They have been disinfected. Operation has been confirmed! (See images 3 and 4 for the lamp lighting up) I am not responsible for any defects due to accidents during shipping (ᴗˬᴗ) The box contains a Type-C charging cable and instructions. Please consider purchasing only if you don't mind that they have been stored by a private individual. Immediate purchase is OK. I want to sell them, so please feel free to negotiate the price!
