The used genuine Sony case at $43.99 is the cheapest replacement option, while the new official case at $49.98 costs about $6 more for guaranteed new condition. The full WF-C710N earbuds in black at $80.93 are a separate product entirely — a complete noise-cancelling headset. For case-only buyers, the used option offers the best value if condition checks out; for new-condition peace of mind, the $49.98 listing is worth the small premium.
