Neptune

Unprecedented Sound Quality, Straight to your apple EarPods

Neptune

Accurate Audio Reproduction

Our patent-pending headphone correction process featured in Neptune transforms your Apple EarPods into a world class audio reproduction device. Using digital signal processing, Neptune linearizes the frequency and phase response of the headphone drivers and implements a realistic stereo crossfeed emulation. Neptune is configured exclusively for your Apple EarPods (wired 3.5mm).

Our most commonly asked question is Why Does Neptune only work with Apple EarPods? Simply put, the technology behind our patent-pending algorithm works best on in-ear headphones, and Apple EarPods (wired 3.5mm) have world class distortion performance. There is not a better headphone in the world for digital signal processing to correct. If you are still skeptical this article breaks down all the science behind why we selected this headphone.

How Neptune Works

Frequency Response Correction (Part 1)

When it comes to high-quality audio reproduction, the frequency response reigns king. In an ideal world (one like Neptune) the frequency response would be linear through the entire audible range (from 20Hz to 20kHz). With our unique headphone measuring system and patent-pending headphone correction procedure, Apple EarPods (3.5mm) paired with Neptune measure completely flat (+/- 1dB) from 60Hz to 3kHz and (+/-5dB) from 47Hz to 20kHz.

Realistic Crossfeed Emulation (Part 2)

From a psychoacoustic perspective, the way sound travels from speakers to our auditory system differs from how it’s delivered by headphones. When listening in the free field with speakers, sound from the left channel will be heard first by the left ear and then by the right ear at a slight time delay and vice versa. It is important to note that the sound that travels to the opposite ear will arrive at the eardrum filtered with mostly low and mid-frequency energy, a phenomenon known formally as the shadow effect of the head. The perceptible difference with crossfeed is an enhanced and natural sounding stereo field and soundstage.
