DD ddHiFi TC05M3 2-in-1 USB-C Charging & OTG Decoding Cable

Eliminate Battery Anxiety

When using a phone with a decoding DAC for music playback, the charging port is occupied, which can lead to battery anxiety over prolonged use. The TC05M3 solves this issue with its integrated charging plug. Simply connect the two cables of different lengths to your OTG device and power bank respectively, allowing you to enjoy music while charging.

Note: Due to differences in USB interface protocols among various brands of Android phones, certain phone models may experience compatibility issues when used with the TC05M3.

Dual-Way Power Supply for Enhanced Audio Quality

TC05M3 seamlessly connects your smartphone, DAC/amp, and power bank, enabling simultaneous device charging while delivering stable power to the DAC/amp. With consistent voltage and current output, it unlocks the full potential of audio decoding and operational amplifier chips for superior sound performance.

Reinforce Construction with Longer, Thicker Cables

Simultaneously connecting audio decoding devices and charging constitutes a high-intensity usage scenario. Only a robust and durable cable can ensure uninterrupted power and seamless music playback. The TC05M3 features oxygen-free copper cores twisted together, wrapped in a double-layer shield of aluminum foil and a cross-weave braided mesh. The outer layer is made of aging-resistant, highly transparent PVC insulation.

Enable 10W Charging

The end labeled "10W" is designed for connecting to chargers, power banks, and other charging devices, supporting up to 10W charging. When connected to a charging device, the simultaneously connected audio output device consumes almost no power from the phone*.

*Testing Notes: 

Scenario A (Power bank + Samsung S25 Ultra + TC05M3 + TC44Pro E3): recorded a max. output of 10.5W. 

Scenario B (Power bank + Samsung S25 Ultra + TC05M3): recorded a max. output of 10.0W.

Boost Durability with Lightweight Plugs

The cable requires three plugs to operate simultaneously, making plug weight a critical factor for user experience. To address this, the TC05M3 features a newly developed lightweight USB-C mold. It is injection-molded with high-strength PC+ABS and reinforced with an aluminum alloy outer ring, achieving a lightweight build without compromising durability
