This product is an audio quality-improving seal for optical discs, utilizing an organic polymer hybrid damping material with the highest level of vibration-absorption performance. Simply apply the 0.3-mm thick ring-shaped seal to the center of a CD, DVD, or other optical disc to absorb the minute levels of unnecessary vibration generated during playback with amazing efficiency, and greatly attenuate the physical and electrical noise caused by this vibration. This makes the sonority, spread, thickness, and subtlety of the sound extremely true to life, dramatically improving the ability to reproduce the original sound. Additionally, the center (remaining) portion of the ring-shaped seal can be used to remove remaining adhesive, or to tune the device.
The number of DS-25 rings has been increased from 11 to 18, thus reducing the unit cost.
Not only that, but further advancements have enhanced the sound quality and enabled a higher level of fidelity.
