A head-worn sound reproduction device is provided in the form of left and right earphones, which can either be clipped to each ear or mounted on other headgear. The earphones deliver high fidelity audio to a user's eardrums from near-ear range, in a lightweight form factor that is fully “non-blocking” (allows coupling in and natural hearing of ambient sound). Each earphone has a woofer component that produces bass frequencies, and a tweeter component that produces treble frequencies. The woofer outputs the bass frequencies from a position close to the ear canal, while the tweeter outputs treble frequencies from a position that is either close to the ear canal or further away. In certain embodiments, the tweeter is significantly further from the ear canal than the woofer, leading to a more expansive perceived “sound stage”, but still with a “pure” listening experience.
