The TANCHJIM LUNA is a balanced USB DAC dongle that runs dual CS43198 chips, one per channel, into a single 4.4 mm balanced headphone output. Pocket-sized and powered by the host device, it fits IEM owners already on balanced cables or planning that move.
Who the TANCHJIM LUNA is for
IEMs on balanced cables: Its one headphone jack is a 4.4 mm balanced output, so balanced-terminated sets plug straight in.
Planning the switch to balanced: Enthusiasts who own more than a couple of sets often end up on balanced cables, and the LUNA is built for that destination.
Phone listening with nothing to charge: It is pocket-sized and draws power from the host device, so there is no charging to remember.
Balanced-first purists: Each channel gets its own CS43198 converter feeding one 4.4 mm jack, instead of effort split across several outputs.
Skip it if: Everything you own is terminated in 3.5 mm; the LUNA has no single-ended output, so a dongle with a 3.5 mm jack is the better fit.

TANCHJIM LUNA vs similar options
vs FiiO KA17: The KA17 adds a 3.5mm output plus a USB-C power input for Desktop Mode; the LUNA is 4.4 mm-only and host-powered. Pick the KA17 if you want either of those.
vs Shanling UA4: The UA4 drives both 4.4mm and 3.5mm outputs from an ES9069Q DAC, while the LUNA gives each channel its own CS43198 and a single 4.4 mm jack. Choose the UA4 to cover both plug types.
vs FiiO BTR17: The BTR17 is a battery-powered Bluetooth DAC/amp (LDAC, aptX Lossless) that also works over USB; the LUNA is a host-powered USB dongle with nothing to charge. Pick the BTR17 to cut the cable.
