1. An earphone, comprising:
a speaker housing;
a speaker positioned in the speaker housing;
a stem extending from the speaker housing;
a conductive object disposed within the stem;
a flexible circuit positioned between the stem and the conductive object;
a material positioned between the flexible circuit and the conductive object operable to move when a force is applied to the stem;
a first sensor electrode disposed within the flexible circuit facing the stem;
a second sensor electrode disposed within the flexible circuit facing the material; and
a shield disposed between the first sensor electrode and the second sensor electrode.

11. An earphone, comprising:
a speaker housing;
a speaker positioned in the speaker housing;
a stem extending from the speaker housing;
a conductive object disposed within the stem;
a flexible circuit positioned between the stem and the conductive object;
a spring member positioned between the flexible circuit and the conductive object operable to allow the flexible circuit to move toward the conductive object when a force is applied to the stem; and
a force sensor electrode disposed within the flexible circuit facing the spring member.

18. An earphone, comprising:
a speaker housing;
a speaker positioned in the speaker housing;
a stem extending from the speaker housing;
a conductive object disposed within the stem;
a flexible circuit positioned between the stem and the conductive object;
a moveable member positioned between the flexible circuit and the conductive object;
a force sensor electrode disposed within the flexible circuit; and
a controller operable to determine an input to the earphone using a change in capacitance detected using the force sensor electrode.
