ddHiFi TC03 OTG Cable | USB-C to USB-C

Exuding "Portable Synergy" at its Core, the ddHiFi TC03 Forms the Perfect Bridge Between Smartphones and High-Performance Portable DAC/Amps

• USB OTG audio decoding cable
• Durable AL6063 aluminum housing
• High-purity OFC conductors
• Three connection styles: Back-Wrap Mode, Dangling Mode, and Side-by-Side Mode

Metal Housing and Braided OFC

The main cable adopts a four-core structure with a mesh sleeve, offering excellent tensile resistance and durability. The conductors are made of high-purity oxygen-free copper and wrapped in Kevlar fibers. The mesh-sleeved cable is soft and skin-friendly, ensuring a burden-free connection experience.

The housings of the USB plugs are crafted from aerospace-grade AL6063 aluminum alloy and precisely machined via CNC technology, striking a perfect balance between a premium feel and robust durability.

Compact Yet Durable

Compact yet durable, the TC03 features a short plug design that minimizes interference when using your phone in a pocket or bag, while reducing the risk of cable bending during daily use. Its smartphone-matched thickness offers a secure, easy-to-grip connection—unlike flat, slippery plugs—making plugging and unplugging effortless and reliable.

Versatile Connectivity for Every Scenario

With "Portable Synergy" as its core design philosophy, the TC03 creates the perfect link between smartphones and portable DAC/amps. 

Back-Wrap Mode
The cable curves along the phone's back to eliminate tangling, delivering a clutter-free experience for gaming or music.

Dangling Mode
Plugs naturally into your phone, hanging freely to avoid palm obstruction, ideal for one-handed commuter use.

Side-by-Side Mode
The angled plug minimizes interference at the phone's bottom, while the straight plug connects to the DAC/amp, aligning earphones in a straight line.
