The impedances and levels are likely to be incompatible between the
phone earpiece output and the stereo headphones. The microphone is
even more difficult as the phone could be expecting a moving-coil or
electret condenser microphone, of widely varying impedance, output and
(in the case of condenser) bias voltage.
On older phones, using the handset socket, the phone could even be
expecting a carbon mic, or an electret substitute.
The headset base adapters that connect into the handset socket of
phones usually contain active electronics to adjust the levels and
impedances to work on a wide variety of phone types. Headset
manufacturers make different versions to work directly off different
