Noise isolating earphones

I know of a thread or two lying around, but this is to do with technology, so best keep up to date!

Any of you got recommendations regarding noise-isolating earphones, for us all to listen to our Katy Perry whilst biking on the motorways? My budget is up to ~£60, but there are SO MANY options that it's impossible to tell which is best looking online. Anybody got a pair that really blocks out wind noise?

Ones that fit your ears well.

May sound silly but I have a few sets that I use for different things.

I use a set of no fear headphones from sports direct that aren't the best at noise isolation. However, they are about £4 a set and I find with the amount of use they get on the motorbike and when cycling/running they don't last that long so I like that they are cheap!

The other good headphones I have are Skull candy that are built well and very comfy, good fitting and even without sound they act as great ear plugs.
