For sure Greg, "caveat emptor" . I haven't read of counterfeit 7506 HPs thus far, but that doesn't mean they don't exist
Good price though.. . The street price at the usual suspect shops are $89-$99
OTOH, the (genuine Sony) MDR V6 (consumer model) are essentially the same for lower yet. I recall seeing them on-sale for $50 USD last X-mas season.
