I’m selling my Sony NW-ZX507 with defective 4.4mm port. All other functions work well but the balanced output doesn’t. It’s hit or miss, so I’m selling as-is. Use it for parts, fix the 4.4mm port, or use it as a streaming Walkman with single-ended output only. The device will ship in retail packaging, and I’ll also include a Miter case. Buyer pays for shipping. I’ll pay for the fees. More pictures upon request.
