We've carried out the sound design of this product based on the latest acoustic engineering and psychological research results. Using the usual method of sound creation whereby certain high frequencies are emphasized, you're given to feel vivid sound when you first listen, but because of this, other ranges become clouded and hard to hear. With E2000, not creating a range that is emphasized makes for clear sound quality. Added to this, giving high frequencies the slightest distinctiveness has you experiencing the same sense of realism you would if the music were played right in front of you. With this product, we've aimed at sound quality that makes the music resound pleasantly for a "standard" whose value you feel the more you use it over time rather than just in its appeal when you first listen to it.

We've carried out the sound design of this product based on the latest acoustic engineering and psychological research results. Using the usual method of sound creation whereby high frequencies are given a sharp peak and certain high frequencies are emphasized, you're given to feel vivid sound when you first listen, but because of this peak, the anteroposterior ranges are masked and hard to hear. With the E series, making the arc of the frequency response smooth overall ensured that no bands were masked, and we achieved high resolution.

With their swing fit mechanism, the earpieces can be swung left and right and tilted towards the audio canal for a perfect fit. These 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.
