I'm not sure if this is a pricing error, but the skullcandy crusher headphones are currently being sold by next (online only) for £30. Available in both white and black.
They retail everywhere else at the cheapest £70 and go up to £110.
Currys currently have them at £69.99, whilst argos and john lewis are £89.99.
I only stumbled across it as I had vouchers to spend at next and didn't need any clothes. I guess Next would be the last place to look for headphones?
I picked a white pair of them up yesterday using their next day in store delivery and they are truly exceptional. At £90 they are a great, but at £30 they are superb. I can also confirm they are the latest model (not the skullcrusher).
The cable control where you can pause music and even answer your phone is great, plus the in built amp with the bass sensation slider truly provides a great listening experience.
Here's a breakdown of the full specs.http://uk.skullcandy.com/crusher
Customer user reviews seem to be great too.
Edit: I should add if you don't choose free store delivery, it's £3.99 home delivery.
Possible quidco too.
