The ddHiFi DJ44B/DJ44C Mark II is a compact adapter that lets a 4.4mm balanced headphone cable plug into a 2.5mm balanced jack (DJ44B) or a 3.5mm single-ended jack (DJ44C), with a gold-plated copper shielding ring at the 4.4mm socket and a 19.4 × 20.8 mm body. It suits listeners with 4.4mm cables who still use players or dongles with 2.5mm or 3.5mm outputs.
Who the ddHiFi DJ44B/DJ44C Mark II is for
2.5mm balanced sources: The DJ44B ends in a 2.5mm balanced plug, so a 4.4mm balanced cable stays balanced on a player or dongle that only has a 2.5mm balanced output.
3.5mm headphone jacks: The DJ44C ends in a 3.5mm plug for the standard single-ended jack on a player, dongle or laptop.
Pocket setups: The body measures 19.4 × 20.8 mm without the plug and weighs 5.6 g (DJ44B) or 6.2 g (DJ44C); ddHiFi made this version lighter and smaller than the earlier DJ44B/DJ44C.
Noise-conscious listeners: ddHiFi added a gold-plated copper shielding ring at the 4.4mm socket to block interference at the socket gaps, and wires the inside with a mixed 6N OCC and 6N silver-plated OCC conductor.
Skip it if: you want balanced drive from a 3.5mm jack (the DJ44C runs a 4.4mm cable single-ended), or your source already has a 4.4mm output.
