Abstract: A computer-implemented method comprises identifying an audio playback device configured to reproduce audio content based on an audio input signal, wherein the audio playback device has a previously measured characteristic frequency response; retrieving the previously measured characteristic frequency response associated with the audio playback device; generating, based on the previously measured characteristic frequency response and a preferred frequency response curve for a plurality of users, a frequency response filter that modifies the previously measured characteristic frequency response of the audio playback device to a modified frequency response; processing the audio input signal with the frequency response filter to generate a filtered audio signal that differs in relative amplitude from the audio input signal in one or more frequency bands; and causing the audio playback device to play back the filtered audio signal.

Abstract: A memory stores a linear model predicting a preference rating for in-ear headphones. A processor is programmed to display a user interface for measurement of headphones; perform a sweep test of the headphone to create a headphone response curve defining a frequency response of the headphone responsive to selection of a measure control of the user interface; and isplay a preference score for the headphone to the user interface computed using the linear model according to the sweep test.

Abstract: A headphone system includes an audio output device, an ear pad coupled to a first side of the audio output device, and an inflatable pouch coupled to a second side of the audio output device. In some embodiments, the inflatable pouch inflates in at least a direction away from the second side of the audio output device.

Abstract: In some embodiments, an apparatus includes an audio generating element; a sleeve including a longitudinal channel, an outer surface of the sleeve including at least a first portion that is expandable in a cross-sectional size in at least one direction; and a rigid insert configured for insertion into the longitudinal channel. At least the first portion of the outer surface of the sleeve expands in the at least one direction when the rigid insert is inserted into the longitudinal channel.
