E4000

Sound design for the E4000 is based on the latest acoustic engineering and psychological research results. It delivers clear sound quality across all bandwidths and a sense of real, true-to life sound. The small-aperture 6.4mm diameter dynamic driver unit boasts an extraordinarily high level of precision for this price range.

With E4000, no particular sound ranges have been emphasized, and this, together with a commitment to detailed sound expression, results in a realistic sensation that sounds as if it were being played right in front of you. In addition, the E4000 uses an MMCX connector that can be re-cabled, in the event of cable breakage.

To heighten the resolution across all ranges, acoustic pressure has been lowered. When you listen, the sound appears laid-back; turning the volume up gradually while assimilating this subtlety affords the user a comfortable listening experience.

The rear housing features an acoustic resistor that controls the low mid-range frequency characteristics. At the end of this, there is a pipe bent into an L-shape (acoustic chamber) which is necessary for tuning; this achieves a balance between the volume of low frequencies and clarity.

The MMCX connector was developed in-company. It features a soft, flexible coated material to help reduce touch noise. When using ear hooks also, it moves flexibly, making for a good fit.

With their swing fit mechanism, the earpieces can be swung left and right and tilted towards the audio canal for a perfect fit. These features prevent changes in shape owing to the aperture of the earpiece coming into contact with the audio canal. The sound is transmitted directly to the eardrum, delivering clear sound.

Compared to a plastic housing, this housing machined from aluminum with a alunite finish firmly supports the driver unit and suppresses unnecessary vibrations.
