Adverts with HEAR or LISTEN and clickable sound clips HOW?

[8556017]

I want to sell CD's, records and tapes. There are lots of adverts listed with HEAR or LISTEN and they have clickable sound clips in them. Would somebody please tell me how to do it as I can not find anything about it on ebay or the internet in general.

Not something I've come across or know about, but I would expect such options to be available only to registered business sellers.

Then why is there nothing about sound clips restricted to business customers only?
