I went for a set of the BOSE quite comfort headphones. These are NOT noise cancelling ones,, they are the cheaper ones (about £140 odd IIRC).

I have to say, they are stunning! Very comfy, and they cut out noise by totally covering your ears. I used them on a Trans Atlantic flight relatively recently to great succuess - Wifey told me that there was a screaming baby most of the way back - I knew nothing!!!!
