Just FYI, is you were to cancel the order through us you'd have to deal with our cancellation policy, which is why @Joeybgood is listing this here.The cancellation would be minus a 25% cancellation fee per our terms and conditions. See here: http://www.zmfheadphones.com/headphone-faq/ A large part of this is that as we build our headphones to order, we order a lot of parts that are not cancel-able after orders come in. And as a small business we have to protect ourselves from losing money on parts that we can't return. Without this policy we'd have to sell our headphones for a lot more, which I don't want to do.The buyer will take over the warranty etc etc. It'd be just as if you ordered through us.If you want to change your order through us, from one model to another, the only cost or refund to you is the difference in price.Hope that all makes sense!
