Audio headphones, especially portable ones, need to be sealed against the ear at low frequencies to reproduce bass. They also need to be "open" enough in the midrange to hear traffic and people for safety reasons.
Can you think of a passive design (as opposed to electronic feedback) which would allow the reinforcement of bass, yet allows voice and warning sounds to be readily audible?
