Westone UM1 (you'd have to import them from the US) - price depends if you have to pay tax or if you don't have to.

Since I don't know the Jays I don't know how they sound - so no recommendation by me.

Anyway.. to give you a clear recommendation we would have to know your listening habits (which music, where are you listeing to music, which headphone style do you want etc.)
