Fiio FH19 VS TangZu Tian Peng

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.

TangZu Tian Peng arrives as a 1DD + 6BA + 1 bone-conduction hybrid around $630–$650 with a striking, oversized shell that still wears comfortably. The build feels premium: sturdy two-pin sockets, a handsome 4.4 mm cable with a reliable chin slider, and a generous accessory spread including Sancai/Noble-style tips and a genuinely luxury case. Packaging is a highlight—easily in the top tier of unboxings and a big part of the product’s appeal.

Sonically, performance sits in the “fine but middling” camp. The graph promises tasteful bass and controlled upper mids, but in practice the low end lacks impact—coming across a bit flabby—while the mids and treble are merely decent rather than crisp or pristine. Extra energy around 4–6 kHz and ~8 kHz can add hiss/edge, and the overall tone could use more warmth (think earlier bass rise near ~200 Hz). It’s an improvement over the discontinued Baji in air and detail, yet still feels short of expectations at this price.

In comparisons, alternatives like Symphony Ears Prestige (clearer tuning with better balance), Mangird/Xenns Top Pro (more pristine, better controlled treble), Shuoer YU9 (smarter bass rise), or even fun picks such as Punch Audio Martillo and the Zigge Crescent offer stronger value or more engaging sonics. The Tian Peng’s bone-conduction implementation brings some charm but doesn’t transform the experience; given the price-to-performance mismatch, this is a hesitant recommendation—worth a demo if the aesthetics and packaging allure, but not the go-to for pure sound quality.

Youtube Video Summary

The Tanchjim Fission presents a neutral, balanced, and clean sound signature that is also described as smooth and full. It offers a very natural and laid-back listening experience, making it a strong option for those seeking a safe, non-fatiguing tuning. The technical performance is solid for its price, with good detail retrieval and instrument separation, though it isn't the most dynamic or sparkly set available.

Tip selection is crucial, with recommendations for the Tri Clear or Final E tips to open up the sound, while the Spinfit CP155 can add a touch more bass. The included tuning switches are largely seen as a gimmick; only the middle silver setting is recommended, as the others introduce a significant sub-bass roll-off. The Fission excels with genres like rock, indie, acoustics, and classical at moderate volumes, but its lack of sub-bass rumble and extension makes it a weak choice for hip-hop, EDM, or rap.

Its greatest strength is its value proposition, as it is essentially a cheaper version of the Tanchjim Origin, sharing the same driver and sound profile for a lower cost. This makes competitors like the Moondrop Kato seem less relevant. However, when compared to other all-rounders like the Juzear 4U or Simgot EW300, the Fission faces stiff competition. The EW300, in particular, offers more bass, tuning variety, and similar technicalities for half the price, making the Fission a tougher sell unless its specific brand of smooth, neutral tonality is exactly what you're after.
