TANGZU Tang San Cai In-Ear Balanced EarbudsNarrow Bore Version
Conical structure designUnlike the previous two versions, the
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.
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 DIAMETER
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.

Four strands of high-purity oxygen-free copper silver-plated wire
Du Fu is composed of 4 strands of high-purity oxygen-free copper silver-plated wires mixed with each other. The signal transmission speed is fast and will not cause distortion and attenuation to the signal. The sound of the silver-plated copper wire is excellent, delicate and moving. Under the protection of the black sheath, the wire stretches freely and is durable.
