Wait a minute...
I do think this is a pretty good deal, but is it really incredible?
This is not Liberty+
60 pounds = about 80 dollars
Liberty in US retails for $100. It has been on sale for $80 before... so it seems to me that it is just the common 20% discount.
And keep in mind Liberty has had mixed reviews. They lack many of the flagship features of Liberty+ and I know many people (including myself) have had serious issues with regards to the fit and them staying in ears.
