Here's how they stack up: **Prices:** itaobuy was cheapest by about 87% **Shipping Speed:** oopbuy was fastest (11 days) **QC Quality:** cnfans had the most detailed photos **Customer Service:** itaobuy responded quickest Overall verdict? For headphones specifically, I'd go with itaobuy. The spreadsheet feature made finding good sellers much easier. Your mileage may vary depending on what you're ordering and where you're located.
