I got the sampler as well. I think it was sent to anyone who has purchased a Sony SACD player in the last 3-4 years and submitted registration with Sony via their website. This isn't the first time I have received a free SACD from Sony. It's ironic as I was thinking the ohter day how I don't have a good set of headphones and I should look into getting some and all of a sudden I get a promotional package in the mail promoting the very thing I was contemplating days before. Not sure if the headphones are any good however.
I got one in the mail yesterday. I almost threw it away. I took the headphone book out and as I was dropping the big envelope in the trash, I realized there was something else in there. I think it's rather befuddling that Sony is promoting a competor's product.
