Product Details

↓ Details provided by DD ddHiFi

The optimized sound tuning

The 4.4mm balanced DAC dongle has gone through the first generation TC44B, the second generation TC44C, and the current TC44Pro, and the sound tuning has been optimized once more. The brand-new internal wires and soldering make the tuning orientation more balanced, and the alignment of digital plugs and analog sockets has been further streamlined.

Pro-level shell craftsmanship

The aluminum alloy is integrally formed, and the wavy surface reflects the delicacy of the titanium color, a new color matching exclusive to the Pro series.

True balance achieved via dual DACs

The TC44Pro features dual CS43131 DACs. For more stable signal-to-noise ratio and dynamic range, the mainboard is symmetrical and designed without openings, and the headphone socket and USB socket are manually soldered with silver solder.

Carbon fiber panel

The back of the TC44Pro is covered with a special 1800D carbon fiber panel, a flexible and lightweight material with a low coefficient of thermal expansion and high thermal conductivity, which effectively protects the internal PCB board.

Thoughtful lanyard hole

The provided leather lanyard is not only a good decoration but also allows you to carry the device around easily and avoid losing.
