Sounds like a pretty big shakeup, despite the "it's all for the best" tone of the email they are sending to customers. The full email has been posted on head-fi, long story short they aren't accepting orders until next year. I'm not interested in waiting.
For me it's while I mow, while I ride, while I snow blow, etc, etc, so it's not hard to justify a little bit of money thrown that way. Basically, the only time I used closed headphone is in a pretty damn noisy environment and also when an over the ear design wouldn't work. IEMs or customs are the best choice.
