NEPTUNE

Optimized Auditory Reproduction:

With the help of our patented digital signal processing correction technology, Neptune not only equalizes both the frequency and phase response of Apple EarPods & AirPods (1st & 2nd Gen), but also features a crossfeed algorithm to simulate realistic loudspeaker listening.

Specific Technicalities:

Without crossfeed processing (which applies to all headphone users without a software like Neptune or Crossfire), headphone listening, and specifically the stereo field, sounds unnatural. This often leads to a hyper-localized soundstage and exaggerated stereo separation. Crossfeed distinguishes speaker from headphone listening. In headphones, each ear receives its respective stereo channel directly. With speakers, low and mid-frequency sounds from both channels leak into both ears with a slight delay, known as the Inter-Aural Time Difference (ITD). When crossfeed processing is applied, headphone listening sounds more natural and comparable to speaker listening. Specifically, low and mid-frequency sounds with stereo information will not give the impression of strict separation between the two audio channels.
