Well I think this may be the deal of the day (better than any Prime deals I have found!)
These are apparently the best noise cancelling headphones you can buy - comparable to the Bose QC35 which cost £330
The price is £330 at Currys
£280 at Amazon
However Currys are offering an amazing 50% off! The discount code is SONYWBW - however this did not work at the checkout.
If you get the same issue just speak to someone on the live chat (pops up automatically) and ask them to generate you a new code.
Hopefully other sites will price match - but I got my order in before the offer is pulled!
This is a great offer and you can see from the reviews here:
