XY-19 wireless earphones with ENC noise-canceling function and LED display. I won these at a festival raffle, but since I already have other wireless earphones, I haven't even opened them and have been storing them at home. Therefore, I haven't checked if they work. Please be aware that I cannot provide any warranty for initial defects or malfunctions. Feel free to ask any questions. I am open to price negotiations, but I may decline extreme offers or repeated inquiries.
