Investigation Report

This listing is for a used Sony Walkman NWZ-M504 MP3 Music Player (8GB, 90% New), sold by the eBay seller "usamzing" based in Shenzhen, China. The seller has a 100 feedback score and a store with about 96 items, mostly used or refurbished electronics from well-known brands like Sony and Apple. The listing was popular, with 24 units sold and 29 watchers before going out of stock. Free shipping and a 14-day return window (buyer pays return shipping) are offered. Payment options include PayPal and major credit cards, providing basic purchase protections. No immediate red flags of fraud or counterfeiting are detectable here, but caution is still important when buying used electronics internationally, especially from a seller without hundreds of detailed feedbacks. The price ($99.99) for a used model is on the higher side compared to some market listings, though no direct evidence of counterfeiting is found. eBay's platform is known to have fake reviews and occasional counterfeit challenges, but as of now, this seller does not seem to have the classic signs of a scam operation (e.g., brand new accounts, ultra-low prices, or missing item shipment complaints). To reduce risk, check the seller's feedback page for recent, detailed reviews and confirm all functions upon receiving the product. Take advantage of eBay's Money Back Guarantee if any issues arise.
