Wearable headset

An earphone is disclosed that is used in connection with reproducing audio sounds that are supplied from an audio-frequency source. The earphone includes a housing that includes a boot assembly positioned in the housing. A first audio driver is positioned in the boot assembly such that a first output of the first audio driver is in acoustic communication with a mixing chamber. A second audio driver is also positioned in the boot assembly such that a second output of the second audio driver is in acoustic communication with a chamber in the boot assembly. A tubular needle is positioned in the boot assembly having a first end in acoustic communication with the chamber and a second end in acoustic communication with the mixing chamber.

A balanced armature apparatus is disclosed that includes dual transducers for generating sound waves in response to electric audio signals. The dual transducers include a motor assembly coupled to a diaphragm. A housing defines an interior chamber and the motor assembly and the diaphragm are positioned within the interior chamber. A pair of acoustic output ports is located in a respective end of the housing. A low pass acoustic filter is in communication with one of the acoustic output ports that is operable to attenuate a predetermined range of frequencies from an audio signal produced by one of the diaphragms.
