I have some headphones that use 3.5 but the connector plastic is quite thick and won't fit through the hole in my phone case.
I believe I am looking for a female to male slim 3.5 adapter. I've seen a couple on TradeMe and in Dick Smith but they are only a few $, worried about the quality / reduction in sound quality.
Where would be a good place to buy one? I'm not familiar with audio stores.
Also I'm wondering if the adapter could get caught in my pocket and bend the pin or damage the phone, would I be better carving a bigger hole in my case perhaps.
