Abstract
An earphone device capable of achieving sound bandwidths beyond the 150-7000 Hz wideband range, and configured for supra-concha or supra-aural placement. The earphone comprises at least two frequency range receivers positioned within a housing. In at least one embodiment, the earphone is capable of achieving a super-wideband range by physically combining a low frequency range receiver and a high frequency range receiver in a space-efficient and acoustically advantageous manner.
