1. A headphone device comprising:
an earpiece;
an amplifier configured to drive a speaker;
a capacitive touch sensor assembly configured to detect a touch-based user input, the capacitive touch sensor assembly including:
a capacitive sensing electrode at least partially integrated into the earpiece, the capacitive sensing electrode comprising a base portion and a plurality of elongated, spaced-apart conductors that extend from, and are coupled to, the base portion, and
a capacitive touch circuit coupled to the capacitive sensing electrode, the capacitive touch circuit configured to deliver a capacitive sensing signal to the capacitive sensing electrode;
a near-field communication (NFC) circuit electrically coupled to a loop electrode, the NFC circuit configured to deliver an NFC drive signal to the loop, wherein the loop electrode and the capacitive sensing electrode are co-located such that magnetic flux generated by the loop electrode propagates through the capacitive sensing electrode;
at least one processor coupled to the capacitive touch circuit and the NFC circuit; and
at least one non-transitory computer readable medium comprising program instructions that are executable by the at least one processor such that the headphone device is configured to:
play back, via the amplifier and the speaker, audio content,
during playback of at least part of the audio content, detect, via the capacitive touch circuit and the capacitive sensing electrode, user input associated with a command to modify playback, and
after detection of the user input associated with the command, modify playback of the audio content.
