Do such converters exist at all though? I have been to quite a few phone
shops, showing them the 3.5mm 3-ring headset connector, as well as the
2.5mm 4-ring earplug. (The latter works, but the headset has better bass
and is more pleasant to wear.)
No phone shop seems to have such a connector. Of course, these people
doesn't actually seem to know that 2.5mm and 3.5mm plugs are
standardized sizes, they keep asking what brand of phone it is. :-(
