Non-intrusive ear buds for iPod Nano

Hi,

I'm afraid that I just can't get on with the type of ear bud that burrows into your ear canal, so I realise it will mean a drop in performance, but I'd like a pair that sit in your outer ear, like the originals supplied by Apple.

Budget, around £30-£40. Music, embarrassingly middle-of-the-road.

Any suggestions gratefully received.

Thanks.
