Kirari I’d angle that silver deer-motif faceplate toward the light and go straight for a close-up. The embossed surface is the styling detail I want to photograph.
Nea The retro vocal tuning makes me want to revisit older CD- and cassette-era recordings. I’m curious how familiar voices would come across.
Snowsky FH3 LUMI is a wired in-ear monitor tuned around vocals and inspired by the character of classic CD players and cassette decks, according to FIIO. It launches in Japan on September 11, 2026, at an open price, with a Japan market estimate of ¥15,950. South Korean pricing and release timing have not been announced.
A hybrid arrangement built around vocals
Each earpiece combines a 10 mm cashmere-and-wood-fiber composite dynamic driver with two custom balanced-armature drivers for the mid and high frequencies. FIIO says it developed the vocal-centered tuning with input from audio enthusiasts.
The manufacturer also describes a fourth-order RLC filter and dedicated notch circuit intended to control sibilance between 6 and 8 kHz while preserving extension above 8 kHz. This is FIIO’s stated design goal, not independently measured performance.
How LUMI differs from the older FH3
FIIO’s comparison presents the older FH3 as an all-round model built with a beryllium-coated dynamic driver, two Knowles BA drivers and an MMCX connection. FH3 LUMI takes a vocal-centered direction, switches to a 0.78 mm 2-pin connection and adds a 3D-embossed deer-motif faceplate.
The detachable cable uses oxygen-free copper, and the earphones carry Hi-Res Audio certification. Independent listening impressions are not part of the available information, so how the retro tuning treats familiar CD- and cassette-era recordings remains a question for an eventual audition.
