When one photo isn't enough, take up to five. Here: three photos of a gaming headset at a flea market, then the seller's price.
Three photos of the headset — the side, the logo and the headband — and a seller's price of $10. FlipTip identifies it as a ROCCAT Elo gaming headset (78% match, with the two closest alternatives) and asks for one more photo that would settle the exact model.
Real sold prices: $17–49 from 16 completed eBay sales, with the new price for comparison. The verdict is SKIP: it sells slowly (30–77 days) and the margin is thin.
Below that: what to check before buying, a negotiation range ($9 → $16), where to sell it and a listing tip.
