These are SONY WH-1000XM4 headphones. I purchased them at the beginning of this year and used them about three times, but they didn't suit me, so I'm selling them. I bought them from the official SONY online store. Since I haven't used them much, there's no dirt or odor, but as you can see in the fourth image, there's a very small scratch. The design is cute and can be used as a fashion item, and the sound quality is also very good, so you can enjoy music.
