SORA-2 is a high-resolution canal-type earphone with the following features through the use of OTSEID's patented VST*1 technology (Vertical Support Tweeter), a high-quality graphene-coated woofer, and a stainless steel housing, and the introduction of HDDS*2 technology. The ability to reproduce the mid-to-high range. The ability to reproduce bass with a smooth feel and low distortion. Reproduction of an unimaginably wide soundstage from a small housing

VST Super Tweeter (Vertical Support Tweeter) … By using ceramic diaphragms, which are used in fishing rods and ultrasonic sonars, as tweeters, they have the ability to reproduce ultra-high frequencies that could not be achieved with electromagnetic diaphragms. By using a unique patented structure (VST) that directs the ceramic diaphragm in a vertical direction, we have created a super tweeter suitable for HiFi.

Graphene-coated woofer … By using a graphene-coated woofer, which is comparable to the hardness of diamond, we have achieved the reproduction of voices with a bright three-dimensional feel, maintaining the vocal reproduction capability of the previous “SORA”. In addition, by optimizing the double dampers to match the graphene-coated woofer, you can enjoy the smooth and soft bass sound that you would never have imagined from a graphene-coated woofer.

HDDS ... The HDSS technology, which excels in air rectification inside the box, has been adopted to achieve a complete sense of realism and low distortion across the entire sound range. This technology, together with the graphene-coated woofer, allows the reproduction of a wide range of mid and low frequencies.
