A sound output device includes a main device portion that incorporates at least a battery and that is positioned behind an auricle, a sound output portion that incorporates at least a speaker and that is positioned in front of the auricle, a connection portion that connects the main device portion and the sound output portion to each other and that is positioned to run up along an ear lobe, and a joint that is removably attached to the sound output portion, that has a sound emitting opening, and that guides sound output from the speaker to an external acoustic opening, in which the joint for one of a left ear or a right ear is mounted on the sound output portion.

A wearable sound system includes a microphone on a movable outer part of an earpiece to convert sound from acoustic input signals to audio input signals; a processing unit to process the audio input signals to generate audio output signals; a speaker on the earpiece to convert the audio output signals to acoustic output signals, wherein the outer part of the earpiece with the microphone is rotatable, wherein the outer part of the earpiece with the microphone is pivotable or laterally extensible and retractable to obtain an optimal audio input signal, and to minimize ambient noise and interference.

This disclosure includes several different features suitable for use in circumaural and supra-aural headphones designs. Designs that enhance user comfort and improve user control of the headphones are discussed. Various sensor configurations and electronic component positions are also discussed. User convenience features that include detachable cushions and automatically detecting the donning and doffing of headphones are also discussed.

A headset having game, chat and microphone audio signals is provided with a programmable signal processor for individually modifying the audio signals and a memory configured to store a plurality of user-selectable signal-processing parameter settings that determine the manner in which the audio signals will be altered by the signal processor. The parameter settings collectively form a preset, and one or more user-operable controls can select and activate a preset from the plurality of presets stored in memory. The parameters stored in the selected preset can be loaded into the signal processor such that the sound characteristics of the audio paths are modified in accordance with the parameter settings in the selected preset.
