ddHiFi TC19BC 95cm USB OTG Cable

Sound Quality, Elevated Once Again
When using a smartphone, tablet, or computer as a digital playback device, the impact of the USB cable on sound quality is more pronounced than data transfer speed. Audio decoding and amplification devices typically employ USB 2.0 interfaces, with a sealed shielding layer ensuring stable transmission speeds and protection against electromagnetic interference.

The TC19 features pure silver conductor material for its data negative and positive poles, equipped with an independent mesh shielding structure. The positive and negative poles are arranged in parallel with equal signal transmission distances, ensuring superior accuracy in system signal transmission.

Four-Wire Parallel Design, Yet Exceptionally Flexible
The all-new TC19 series data cable arranges the four conductors-power positive, data negative, data positive, and power negative-in parallel.

The cable's width matches the socket size of a smartphone. This neatly aligned conductor structure demands extremely stringent production requirements for twisting equipment, with slow and precise weaving and insulation wrapping to ensure uniform thickness and a supple cable body.

CNC Metal Seamless Shielding Shell Design
The Signal Interference Terminator, Born from Precision Structural Aesthetics
Signal interference from smartphones and computers often originates from electromagnetic leakage at plug joints and soldering points. The TC19 adopts a CNC-machined, one-piece metal upper and lower casing with high-precision interlocking seals, forming a zero-gap fully enclosed shielding cavity that completely isolates internal signal circuits from external interference, eliminating electromagnetic crosstalk at the source.

Curved Ergonomic Design for an Enhanced Plugging Experience
The tail end innovatively incorporates a curved protrusion structure that aligns with the natural arc of finger movement, making plugging and unplugging more effortless and intuitive. The collision of rigid metal texture and soft curved lines blends functional practicality with visual aesthetics, offering a dual sensory experience of craftsmanship and design with every touch.
