FiiO
SNOWSKY OAK NANO
No Score
FiiO
The OAK NANO was supposed to be the FiiO FD17, the direct sequel to the 2021 pure-beryllium FD7. Supply chain trouble killed the pure-beryllium plan, pushed FiiO to a beryllium alloy driver, and moved the project under SNOWSKY instead of the main FiiO badge. Then it landed at $449. That badge-to-price mismatch drives the first reaction. Early coverage guessed $180 to $250 because SNOWSKY and Jade Audio usually signal the direct-to-consumer or experimental side of FiiO, not a flagship single-DD built as the FD7 spiritual follow-up. What buyers actually get is easier to pin down: a 13.8mm beryllium alloy dynamic in a titanium alloy shell, plus 22 tip pairs, a leather and suede case with drawers, a magnetic wire roll, and an accessory spread that borders on ridiculous (22 tip pairs will do that). Build is the easy part. Coverage keeps circling back to watch-grade tolerances, and the cable is not filler either: cryogenically treated silver-plated monocrystalline copper, 8-wire, modular, and terminated for 3.5mm, 4.4mm, or USB-C. That USB-C end matters. It carries hardware-level 8-band PEQ through the FiiO Control app, which much of the coverage treated as the real premium add-on buried under all the suede and drawers. Where the consensus splits hard is sound. Stage width is the cleanest divide: one camp heard an extremely narrow, intimate presentation, the kind of in-your-head imaging single-DDs can throw, while another heard a wide, open stage and tied it to the semi-open acoustic design. The tuning read is just as messy. Depending on the listener, this lands as Harman-adjacent and energetic, mid-forward and not especially Harman-ish, or a flat-out fun V-shape. Same IEM. Very different maps. There is one easy callout buried inside all that disagreement. The default black-ring nozzles are the stock tune, but the recurring recommendation was to swap to the red-ring set for more low-end lift and more detail, then leave the stock cable alone because FiiO clearly spent money there. After that, the shared language settles on the same traits: cohesive single-DD timbre, fast transient response, and a presentation that does not read dry or analytical. At 50 ohms and 112 dB/mW at 1kHz, the OAK NANO is not especially demanding, and the included USB-C termination makes the usual source-gear scramble less urgent. Hardware PEQ is already in the box. More than anything, the OAK NANO shows how much branding can distort a launch. The arguments about stage and tuning are real, but the first hurdle here was never driver tech. It was convincing people that a SNOWSKY badge could carry a $449 flagship at all.
