Open-ear headphone 10 body 14 is coupled to acoustic module 12 and includes a first portion 16 that is configured to pass over the outer side of the ear (e.g., at least one of the anti-helix and helix and lobule of the outer ear), and a second portion 18 that is configured to be located behind the outer ear. Body 14 is generally “L”-shaped from the side (as shown in FIG. 2) with portion 16 running at about a right angle to acoustic module 12, connecting portion 17 running at about a right angle to portion 16 and leading to distal portion 18. In an example portion 18 can be generally cylindrical such that it is configured to hold a generally cylindrical battery power source (e.g., a rechargeable battery). Overall, open-ear headphone 10 is generally “C”-shaped, as shown in FIG. 2. In an example acoustic module 12 and body 14 are parts of a unitary molded plastic housing that is constructed and arranged to contain the transducer, the battery, and any necessary electronics for operation of the headphone.
