Nice All BA set!
Youtube Video Summary

Fiio FA19 brings a premium feel: a sturdy, slightly translucent shell with visible BA packs, comfy fit, and a plush eight-wire cable that terminates in 4.4mm. The MMCX sockets aren’t ideal, but the shell is vented, holds tips well, and the magnetic case feels upmarket. Sonically, this 10-BA set leans warm-neutral with a rich, cohesive presentation—male vocals sound full, some female vocals come off a bit husky, and bass has quantity more than tightness. There’s a touch of 5–6 kHz energy and slight hiss; treble is clean and pleasant rather than showy. The bass switch mostly bumps mid-bass; the lower setting keeps things tidier. Overall it’s Fiio’s most well-rounded tuning to date, just shy of “exceptional” because of that soft mid-bass and a mildly flabby midrange.

Versus peers, FD15 sounds more neutrally tuned (if less special), while all-BA options like Supernova feel more natural and controlled down low. In the wider field, sets like Letshuoer Mystic 8 (a bit of a sleeper), ThieAudio Monarch MK4 (cleaner upper-mids, dual bass settings), ZiiGaat Luna (tighter, crisper for far less money), or even budget-friendlier picks such as YU9 can offer a stronger value proposition. At around $1,000, FA19 earns a solid recommendation for those who enjoy a warmer, airy BA take—graded roughly A4 / S-—but it’s a demo-first purchase and shines much brighter if found used around $300–$400. Not a new benchmark, yet a very good Fiio with treble finesse and a smooth, easygoing signature that many will simply enjoy.

Lack Bass Richness, but is a beautiful set.
Youtube Video Summary

Build and presentation hit above the price rumor: a dense, metallic shell with a sleek “cat” motif, excellent nozzle/fit, and a surprisingly handy case with a rubber lid that’s easy to pop open. The 8-BA array (Sonion + “NSBA” branded drivers) gives it pedigree, while the stock cable feels a bit chintzy despite a 4.4 mm termination and chin slider. Final pricing isn’t set (the placeholder listing is a meme), but the talk is roughly around $1,000, which frames expectations for the rest.

On tuning, Mystic 8 comes across reference-lean, very clean and clear, with extended upper-mids/treble and a lighter bass shelf. It’s a laid-back, chill listen with strong micro-detail, imaging, and stage, but the macrodynamics feel reserved and the bass lacks some rich, organic texture; hip-hop and slam-seekers may bounce. A small EQ bass lift (sub/mid-bass shelf) unlocks body and brings the set to life without breaking its neutral poise.

In context, it outclasses Cadenza 4 for naturalness and timbre, while Cadenza 12 (2024) offers richer bass but has an odd upper-mid quirk and a much higher tag. The FR echoes the Monarch Mk II; if Monarch felt light down low, Mystic 8 won’t fix that, though it crushes it on shell/build. Versus sets like Thieaudio Origin (bigger shell, weaker micro-detail), Canpur Verdandi (more bass/upper-mid bite), or DAA Mecha (fun but not neutral), Mystic 8 positions itself as a refined, mid-focused all-BA with standout technicals and an ownership appeal. As a ~$1k competitor, it’s compelling—just not the most visceral/engaging without that tasteful EQ nudge.
