The Shure MPA expected to be released in August has arrived. It is now for sale at the Apple Shop and is marked as shipping within 24 hours. I know this has been mentioned in another thread, but for the sake of people searching, I thought this new accessory was worthy of it's own thread. For people with EC4 (or EC3)....I am going to call Shure and ask if they will convert them to a modular cord if I send it in (at my cost of course). As it is now, I'm not sure that I want the Shure adapter because there would be a lot of extra cord.
