The ddHiFi TC44Pro M3 (Mountain3) is a T-shaped USB-C DAC/amp with an integrated 3.5mm + 4.4mm socket, dual Cirrus Logic CS43198 DACs, 120mW balanced or 90mW single-ended into 32Ω and native DSD256, in an 11g striped aluminum-alloy shell. It suits IEM listeners who switch between single-ended and balanced cables on a USB-C device.

Who the ddHiFi TC44Pro M3 is for

  • Mixed cable collections: The integrated socket takes both 3.5mm single-ended and 4.4mm balanced plugs, so one dongle covers either cable.
  • Plug-in carry: The T-shaped body plugs straight into a USB-C port, weighs about 11g and has a lanyard hole for the included leather lanyard.
  • Hi-res and DSD files: Dual CS43198 DACs decode PCM up to 32-bit/384kHz and native DSD64/128/256, and a side light shows blue for PCM and green for native DSD.
  • Android DSD playback: For native DSD on Android, ddHiFi says the player app must enable USB exclusive mode and set DSD output to Native.
  • Skip it if: You need high power for demanding full-size headphones: ddHiFi rates it at 120mW balanced and 90mW single-ended into 32Ω.
