Out of the blue, a Sony PR agent dropped me an email.
"Sony has recently introduced the new high-quality Studio Monitor Series headphones that boast premium sound and technology, and I wanted to see if you are interested in reviewing them."
She referred to four headphones in her email (two full size sealed MDR-ZX700 ($119.99) and MDR-Z1000 ($499.99), and two IEMs MDR-EX600 ($199.99) and MDR-EX1000 ($499.99), but only had the inexpensive ones for review samples at the moment.
Oh .... okay. I'll take the cheap ones and have a listen. Glad I did.
