These are the cheapest these have been to date. I ordered a pair last night from Amazon for £13.34 for a birthday present and thought I would get myself a pair as I was undecided last night only to find they have dropped in price overnight! (I have asked for a refund of the difference considering the time frame, awaiting a reply).
Anyway, these have been posted no end of times but as I say these are the cheapest to date and thought it was worth posting again.
ALSO you can get a £2 credit towards MP3 downloads.*
Reviews on these are second to none.http://www.sennheiser.co.uk/uk/home_en.nsf/root/private_headphones_classic-line_cxseries_502737
