The "SednaEarfit" series features a basic design and shaft structure based on analyzed data, enabling a high level of fitting and fixation to the earphone nozzle, while also improving sound insulation, and improving high-frequency characteristics along with natural tones. These are high-grade replacement ear tips. ■ Uses the highest-grade German premium LSR SednaEarfit Crystal uses the highest-grade German premium LSR (Liquid Silicone Rubber), which has the characteristics required of ear tips at a high level, as a result of long research and repeated prototyping and testing to achieve the Pressure ZERO Design. ■ Acoustic design specialized for 3D surround In terms of acoustics, we designed and tuned for clear sound and rich tones. The interior adopts a horn shape to ensure a wide sound stage and clarity due to the directivity of the sound. In addition, we have designed it to express a punchy, true deep bass, rather than emphasizing the general bass band. This allows it to demonstrate high acoustic performance in content. ◆ About the Condition ◆ I purchased the wrong size, so One pair has only been tried on, and one pair is completely unused. ◆ From the Seller ◆ I am selling these because I have no opportunity to use them.
