I agree it's probably easier to fence individual stolen items.
OTOH, I think your argument assumes criminals are lacking creativity... and that the police care and/or have the resources to track $8K worth of headphones. If $8K of headphones are stolen, how many % of total headphones sold on eBay/CL/FB/etc. per month is that? Also, who says they have to offload all the headphones immediately? What's to prevent a "criminal network" or a single person from creating 20 different eBay accounts, each selling one pair - location: obviously not near where they were stolen from. Repeat process once per x months or just wait a few months until the heat is lower. Or perhaps pass the headphones on to a larger "criminal network" who can resell them all over the US. Also on eBay one could just say "shipping from northern California" when in fact they are located in Southern California - who will verify that? Also you could take a few pair to pawn shops... some might even take multiple pairs at once. Also someone could gift a bunch to friends/family. I'm sure there are tons of tricks criminals use to offload stolen goods.
