Conical structure design

Narrow Bore version features a completely new internal structure with a conical design. After repeated testing and modifications, this structure complements the Narrow Bore's characteristics, and adjustments to the hardness and length of the tube ensure the precise path of sound waves at the speed of sound. Besides the internal structure, the Narrow Bore version also has a different appearance from the previous two versions, designed with a double flange-like shape for deep insertion.

Special Ear Tip Texture Design

- Pressure release grip system.
- The unique patterns on the ear tips serve a dual purpose: efficient pressure release and a secure, comfortable fit for long listening sessions.

Narrow Bore

- The diameter of the bore or the hole plays a crucial role in sound balance and performance. During the development process, we conducted analysis, experiments, and tests to achieve the ideal sound target effect. While maintaining sound clarity, the Narrow Bore version enhances the low-frequency quality and reduces high-frequency harshness.
Medical-Grade Hypoallergenic Material
- In terms of both sound and user experience, Tang San Cai uses medical-grade silicone material to minimize any possibility of allergies.
