A very pleasing Colorization, but not exactly what I love.
Youtube Video Summary

Build and accessories are a clear win: a sturdy, comfortable, slightly translucent shell with MMCX connectors, a plush 8-wire cable terminating in 4.4 mm, and a premium magnetic case. As a 10-BA set around $1,000, it wears a tasteful black-and-silver faceplate and seals well without pressure issues. There’s a bass switch that nudges mid-bass upward; useful for taste, but not essential.

Sonically it’s a warm-tilted, cohesive presentation: male vocals come through full and rich, female vocals can sound a touch husky, and the mids avoid shout. Treble is clean and pleasant with a bit of 5–6 kHz energy that stays in check; overall clarity is good, though there’s slight hiss and the mid-bass can feel a little loose/flabby rather than tight. Stage and detail are solid, making this arguably one of FiiO’s better efforts, but the value is mixed—graded a strong A4 / S-: recommended if it suits the tonality, yet tough at retail amid fierce competitors; far more compelling on the used market or after a thorough demo.

It's like a Pilgrim OG with EST. It's kinda cool.
Youtube Video Summary

Build & accessories impress: a chunky yet comfortable shell with a secure 2-pin connection and a nozzle lip that holds tips firmly. The faceplate design looks premium, and the stock cable feels good in hand with a chin slider and swappable 4.4 / 2.5 mm terminations (though the modular plug can loosen under tug). The familiar Thieaudio case and standard tip set round out a solid unboxing.

On the graph and in practice, the Oracle MKIII takes a more neutral approach than MKII—less bass, tamer upper-mids. It shares territory with sets like Hype 4 (trading blows: better upper air here vs. stronger upper-mid presence there) and recalls the Pilgrim with added EST sparkle. There’s extra 4–6 kHz bite and energy in the 10–15 kHz region that can become fatiguing over longer, mixed-content sessions. In context, similarly priced options—Supernova, Noir, and Hisenior Mega5 EST—offer comparable performance with different tonal priorities, while budget picks like Hidizs MP145/MP43 or curve-match contenders such as Juzear 61T and the upcoming Binary Dino Quattro complicate the value equation where many ~$300–$400 IEMs trade blows.

Verdict: gorgeous build, good extension and upper air from the ESTs, and a generally chill-neutral tonality—yet the emphasized presence/treble bands make it a fatiguing neutral for sensitive ears. Rated a solid A for quality, but not a universal pick or a clear recommendation over peers; those who loved the Pilgrim are the most likely match, while others may prefer alternatives with either fuller bass or smoother upper-mid/treble energy.
