I know their supposed to be 'close enough' but actually it's driving me crazy.
An 1/8" plug is actually 3.175mm, ever so slightly smaller than 3.5mm

This causes headphones with a 1/8" plug to not fit snug enough into my Japanese
radio headphone jacks, which in turn causes the headphones to only work in one
ear unless you maintain slight pressure on the plug to make proper contact.

Anyone else have this prob? Any solutions? Did a Google search and there are
no 1/8" to 3.5mm adapters.

thanks
