Just want to recommend these. They are excellent and are one of the best earphones around even for the price of under £30. There are many reviews on: http://www.head-fi.org/forums/f4/review-…

Free worldwide shipping and no customs taxes etc. They can be bought from Jaben.net

Excellent customer service and great products.

XBi is more bassier and thats the only difference however the x3i has enough bass for most people
What countru are you in? This will determine the shipping time!!!
