This may or may not be hot for people, depending if you are a audio enthusiast.
I do not own this headphone but I've seen nothing but positive reviews round the web. The debut price last year was over £250, and according to reviews it outforms any speaker sets at that price range.
The current price is cheapest in the UK after a brief search.
There is a possible £6.36 quidco cashback, depending on if the voucher voids the cashback.
Use voucher code AFXDEN for the deal.
I shall add that the voucher is for any Denon branded headphone, so if you don't like this one there are alternatives.
