↓ Details provided by DD ddHiFi

"Eye", second generation

The eye is ddHiFi's wired variant of USB DAC Amplifier dongles. The design has only one interface, and the shape is centered like an eye. The wires of the second generation Eye sport all pure silver shielded conductors, similar to the entire 07 series of pure silver conductors used on TC44Pro E2, which is solid and durable while ensuring resolution and detailed performance.

DD ddHiFi TC44Pro E2 USB DAC to 4.4mm Balanced Adapter Overview

Tuning, not just high power

TC44Pro E2 uses two CS43131 decoding chips and two ES9603Q independent operational amplifiers. The chip's nominal power is more than that of TC44Pro, and the output amplitude is limited to 80% to ensure overall listening comfort.

Use materials to make 4.4 sound better

The socket features the Pentaconn 4.4 mm plug from NDICs, coupled with the circuit board developed using a double-layer stacking process, and is manually assembled using lead-free solder containing 3% silver. The top of the socket is enhanced with a reinforced metal ring, which is beautiful and protective.

DIY, take up the leather rope

A simple arrangement can make it look shorter, and the cowhide rope paired with the metal shell is more pleasing to the eye. In addition to the already tied leather rope, the package also comes with a 30cm leather rope. Scanning the QR code on the packaging bag allows one to try to DIY one's own "snake knot".

Status indicator light

There is an indicator light at the front; the light is gentle, with blue representing PCM output, green representing native DSD decoding output, and TC44Pro E2 supports up to DSD256 native DSD decoding.
Reminder: Due to the limitation of iOS output current, at a higher volume state (greater than 85%), it may cause the iPhone to stop playing. You can restore it by re-plugging the tail and adjusting the iPhone to a lower volume state.
