T-500 Silicone IEM Earphone Ear Tips, Low-Frequency Enhance-2 Pairs (L) | Replacement Ear Pads with Patented Air Pressure Balance Structure, Comfortable Fit Eartips Suit for Most In-Ear Earbuds

High Sound Wave Guide Damping StructureAn acoustic innovation born from the compact High Sound Wave Guide. A V-shaped ring pattern is placed on the inner wall of the earpiece's sound hole. This geometric structure guides the phase of high-frequency sound waves, suppressing resonance peaks above 10kHz generated by the coupling between the ear canal and the earpiece, reducing distortion caused by interference.; High-Frequency Waveguide Damping StructureA V-shaped ring array is integrated along the inner wall of the eartips sound outlet, forming an acoustically optimized structure for high frequencies. This geometric design guides and aligns high-frequency sound waves, suppressing resonance peaks above 10 kHz that occur when the eartip couples with the ear canal.

; Dual Hardness Silicone Multi-Layer StructureOuter Cap: Low-hardness, high-transparency silicone (Shore hardness 0) improves fit within the ear canal.
Inner Tube: High-hardness silicone (Shore hardness 65 or higher) ensures stability of the wave guide structure.
Reinforcement Structure: The V-shaped waveguide surface on the inner wall of the outer layer functions as a radial reinforcement rib, preventing sound leakage caused by deformation during wear.; Sound Port Acoustic OptimizationThe Sound Port is designed with an outward-curving acoustic surface that smoothly connects the inner tube and cap section of the earpiece. This unique structure ensures smooth transmission of sound energy while suppressing
