Sound quality design based on the latest acoustic engineering and psychological research results. Clear sound quality that makes music resound pleasantly. 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.
