"Sony engineers and music artists identified the critical 30-40Hz sub-bass region that is signature of today’s music styles and developed an enhanced Beat Response Control design for the new MDR-1 headphones, featuring a closed back for maximum isolation and exceptional bass response. With enlarged air vents at the back of each driver, music lovers experience a quick and rhythmic low frequency response."
and price and release date:
"will be available in November 2012 at Sony Stores, including online at http://store.sony.com, and other authorized retailers nationwide at the following pricing: MDR-1R, about $299, MDR-1RBT, $399 and MDR-1RNC, $499. "
