Abstract
An acoustic device with a housing with a central portion and first and second leg portions that depend from the central portion, a first acoustic driver carried by the first leg portion, a second acoustic driver carried by the second leg portion, and an audio signal control system that directs audio signals to each of the first and second drivers, where the drivers transduce the audio signals to output sounds. The audio signal control system is arranged to apply first and second equalization modes to the audio signals in a first and second listening mode, respectively. The second equalization de-emphasizes frequencies below a first threshold frequency and boosts frequencies above the first threshold frequency.
