You will be able to but these direct from USA for www.earphonesolutions.com @ 399.99/USD (210/GBP) - ignore the price displayed @ 499/USD, click the link for 'special' prices to see real price
& on www.discountheadphones.com who advised me they hope to sell for 360/USD (190/GBP) - not listed in stock yet..
* bought E4C previously from them, very good/efficient to deal with and you get real replies to any queries, as opposed to preformatted templates etc + they allow you to rtn them if not happy with sound quality for a small restocking fee - can't go wrong.
50% saving against your expected price; if you have the patience, which is always hard when you decide to buy something, or for me at least
The same rules apply to all authorised distributors, including DiscountedHeadphones, which is Paul @ iDealSound.
There are ways around this if you have friends or relatives in the USA, but direct shipping will only be undertaken by non-authorised dealers, and you'll void your warranty that way, which isn't really worth it on a pair of cans this expensive, if you ask me.
Still, you pays your money and you takes your choice. Just thought I'd point out a few things worth knowing.
There's a fair degree of people accusing the regional distributors of profiteering. I've bought E2s, E3s and E5s from these places before, but it seems to have happened once the E500 came out. The whole thread on Head-Fi raises these points, but you're welcome to try your luck ordering anyway.
Shure did honour pre-orders as customers weren't forewarned, but orders going forward will, supposedly, be rejected if they're outside of designated territory.
