This US retailer is selling the Sony's for only $385, which should be less than £300 landed, including shipping and import tax.
The only place I noticed the Sony's still for sale in the whole of the EU (including UK) was a couple of places in Poland for £350 ish.
Yeah they are marked as discontinued on the Sony UK website. They are fairly expensive and I have a pair of IEM's on order as well so the yamahas are sounding very appealing! But I will read up on the Sonys a bit more.
