Headphones for 8...11 y.o children.

I don't know what your budget is but I think you should consider the Sony MDR V6 headphones for the young ones. They can be had for under $100 and can take a pounding. I have them and use them for all sorts of listening when my other headphones aren't needed. They are not as pretty as Skull Candy or Monster Beats but IMO they sound a lot better. Excellent SQ and very flat. The only issue they may have is with perspiration if they wear them for a long time. There are velour pad replacements that help with this.
