Ear Phones that don't fall out

[Euro_Hunter]

After a good set of in ear phones that don't fall out easily whilst I am working to be connected to my Sony MP3 player.

Sound quality not too important as there is always something going on in the background.

Looking to pay no more than £20 but would pay more for something very special.

Thanks.

So far looked at KOSS Spark Plug & SkullCandy Smokin & Full Metal Jacket any others I should be looking at?

I have quite small ears.

I have the original Sony ones thats are pretty high quality except the rubber pads fall off easily and they still fall out of my ears at every opportunity

These are the sort of thing that I would like but not paying £70:

Mine didn't come with EX71's, mine are noise cancelling earphones don't know the model number though but the MP3 player is the NW-S706F.
