Query: Clunky and useless!

I'll make this short and sweet - this case would only be marginally OK (clucky, heavy, and difficult to open) if I could use it, but since any set of earphones/headphones/earbuds that has a connector larger than the standard tiny Apple earbuds renders this case completely useless, as the headphone plug will not fit through the case opening. So my Grados, Sennheisers, Shures and everything I else I have in the house won't work with this case. You have been warned!
