1. A portable listening device comprising: a speaker;
a wireless antenna;
a rechargeable battery;
one or more electrical contacts arranged to couple power to the rechargeable battery;
a housing defining a back volume behind the speaker and a front volume in front of the speaker, the housing further defining a nozzle acoustically coupled to the front volume, wherein:
the nozzle forms an acoustic port arranged to direct sound generated by the speaker into an ear canal of a user;
the nozzle includes a tip and a distal portion opposite the tip; the
distal portion is coupled to the back volume; and
the nozzle is continuously tapered from the distal portion toward the back volume; and
an accelerometer positioned within the housing, and configured to detect a user input on the housing.
