Thanks for the advice regarding the travel case. I called the hifiman online store and asked the question about storing the he-400's without removing the cables and was told that it was possible. Can you please clarify your statement regarding this? Is it only possible by forcing the headphones...

Thanks for the info ninjames. I was also deciding on the e17 or the upcoming e12 which has much more power than the e17. Wondering if I should wait for the e12
