High-resolution playback earphones that connect directly to Lightning. The sound quality is significantly better than a standard 3.5mm headphone jack. Purchased for playing high-resolution audio from Apple Music. Selling because they are no longer needed. I think they are in good condition with little use. New price: Approximately 8,000 yen The sound quality is quite good. The included ear tips are unused, and expensive round-type ones are included. Please refer to reviews on SNS and e-earphone.
