Sorry for not responding sooner, yes it's an import /warranty issue, they are buying from oversea's & certainly aren't a Jay's authorised stockist. I'm not saying all of there range is like that, but you need to read the there Terms & Conditions of Sale and be aware.
For example Jay's direct offer a two year warranty, whilst if you read iHeadphones T&C's you'll discover that they only offer, & I quote "free from defects for 6 months from the date of dispatch".
Jay's direct informed me that firstly that iHeadphones weren't an authorised stockist and secondly, because I hadn't purchased from an authorised Stockist it's wasn't their responsibility to replace a faulty product, as my contract of sale was with iHeadphones not them.
When you make a purchase from iHeadphones, you're 'Contact of Purchase' under UK law, is with iHeadphones; not the manufacturer. Now remember iHeadphone only offer a six month warranty against faulty goods.
In other words, after six months you are either totally stuffed, or at the goodwill of either iHeadphones or the manufacturer should a fault develop.
