Earphone Adapter for Dopod 585 (amadeus)

[Guest csc12345678]

Hi !

I have a Dopod 585. I don't know which variant it belongs to. I think it's a amadeus (if such an variant exist).

I have a question regarding the earphone adapter. Can I use a 2.5mm to 3.5mm adapter to connect a "normal" earphone (3.5mm without mic) to the smartphone ?

If the answer is yes, then when the earphone is connected, would I still be able to speak through the mic on the phone ?

Thanks.
