When my 13yr old wears his Beats I do not hear anything, they appear to contain all the noise. I suppose it would depend on the volume, but if your childs heart is set on them for xmas maybe limit the time they are used for. I haven't heard of any health and safety issues, but am concerned for my childs hearing, due to the type of music listened too. There is not much room for adjustment in the headset, so they might be a bit big. I hope this helps.
