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.

Smooth dark, and enjoyable.

Youtube Video Summary

Hisenior Mega5-EST +Bass comes as a custom set with personalized shells and a straightforward Pelican-style case. The build is compact and comfortable with an easy tip-lip, though the color matching can look inconsistent in certain light and the stock cable feels a bit lackluster—thin, slightly stiff, and not as plush as expected at this tier.

Sonically, this is where it clicks: a tasteful bass shelf for proper foundation, pristine upper-mids for clarity, and airy EST extension that brings out detail without harshness. It tracks close to a personal target shaped by sets like the Elysian Annihilator and JM1—cleaner and more engaging than the stock Mega5-EST, which can feel like “clean water” to some. Comparisons paint the path here: the affordable Hexa shows the right upper-mid behavior; the Chopin is a fun benchmark under $200 with small quirks; Hype 4 offers a Mega-style tuning on a budget but with less bass; and Binary Dynaquattro scratches a V-shaped itch while being harder to drive. Mega5-EST +Bass blends these lessons into a punchy, articulate, and well-imaged presentation.

Value is strong for a custom with EST drivers under a grand—excellent channel matching, convincing technicalities, and a tuning that feels “just right” for modern music without turning strident. Caveats: the order process can be slow (think weeks) and communication runs through Hisenior/Facebook, so patience helps. Not the only answer at the price, but as a preference-targeted custom that adds the missing low-end weight to the original Mega5-EST’s clarity, this one earns an unapologetic S-tier.
