Thank you for viewing. This is a digital audio player from SONY, compatible with high-resolution audio. As expected from SONY, the sound quality is extremely high. It's perfect for enjoying your favorite music at home in a relaxed atmosphere. I recently purchased it on Mercari, but I'm selling it because I don't have a chance to use it. I was concerned about the size, so I've never taken it out of my house. After purchase, I had the genuine leather case on it, so it's in pristine condition. The genuine leather case is included. There are some bubbles on the protective film, but there are no scratches, and it's like new if you peel it off. All the accessories that came with the purchase are included. Needless to say, there are no operational issues whatsoever. - Model Name: NW-ZX707 - Storage Capacity: 64GB - Connection Terminals: USB Type-C - Features: High-resolution audio support - Size: Compact Model Name: ZX Series ZX Series / Model Name: NW-ZX707 Audio Features: High-resolution audio, balanced connection, DSD native playback Network Features: Bluetooth Network Features: Streaming service support
