Best Wireless Headphones - £300

[Kanpai]

So I was looking to buy a pair of wireless headphones this xmas and had my sights set on the Bose QC35, however thought I'd ask to see if anyone had any other recommendations at the £300 mark price range?

I am quite keen on them having noise cancelling technology and a good enough lasting battery.

Thanks

Cheers fellas, it's gonna be either the Sony or Sennheiser I think, but a package is under the Christmas tree which looks like it could be a pair of wireless headphones, so I will wait until Christmas day to see what fate lies ahead .

I have the P7 Wireless. I really love them. If you buy direct you have a 60 day trial.

What sound signature would you say they have?

Thanks for all the suggestions guys, think I'll head into store and have a listen of all the suggestions and take a viewpoint from there.
