I know we're going to get some people saying "why pay £60 for a set of headphones"?! But these are Bose, and that means quality, as far as I'm concerned. I tried these out with a friend, and they are brill. Use one of the £10 discount code attached below, they have free delivery at the minute as well, making these £59 delivered.
Quidco.com - might be 5 - 8% cashback as well, not sure what category these fall into.
Blurb: Enjoy full, rich sound with distinct clarity and warmth with the Bose© in-ear headphones. They incorporate Bose© Triport technology for greater low-frequency output and a more balanced, lifelike sound.
