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 E3000, not creating a range that is emphasized makes for high definition and a vast sound stage. With well-balanced sound reproduction from low through to high frequencies, you can experience the same kind of sound spread you would if you listened to music in a concert hall. With this product, we've aimed at natural sound quality 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.
