This is potentially a great idea. A cable tidy for headphones is just what is needed for some equipment, like my Sony headphones. However, the item is tiny and is clearly designed with ipod ear buds, or similar, in mind and not anything more substatial than that. The space to wind the loose wiring is not very deep so you can't really get much wire round it. If a larger unit could be designed to encorporate those of us with 'grown up' head phones - this would be great, but as it stands this should be marketed as an ipod accesory and not for the wider headphone market, at the very least it should clearly state that it is not for larger makes/models - maybe I've missed something in the description? Disapointing but with the potential for development.
