Headphones for £20, noise cancelling any good ?

[Tampon]

I have just broke a pair of Panasonic headphones that I wear when watching the MotoGP and F1 to save the wife complaining.

The last pair cost me £15 an were great so now I am upping the budget to a heady £20! I can get sennheisers 201 and 205 for this price, but I have found some cheap noise canceling ear bud ones for £15. Now if they are any good I might use them on the motorbike when commuting into london. Right now I just use cheapy bud ones and turn the volume right up to combat the wind noise. Kill two birds with one stone.

So cheap noise canceling headphones do they work ( I don;t mean in comparision to expensive ones but in actually canceling some noise compared to other cheap non canceling headphones ). If not any recommendations for headphones ?

I bought a pair from 7DayShop just before flying to Canada this summer and was really surprised how good they were for the money. Certainly good enough for the flight movies (and on ipad/iphone for film/music too). Would I recommend vs £250+ for Bose.... yes!
