TangZu Tian Peng VS Softears RSV MK II

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.

Softears RSV MK2 shifts from the OG’s vocal-centric tilt into a bass-forward all-rounder. The sub-bass and mid-bass hit with real slam and weight, giving drums and bass guitars a satisfying, dynamic punch. Upper mids (3–6 kHz) are tamed to avoid shout, while a gentle 1–2 kHz rise keeps vocals open and natural—slightly less pushed than the original but still clear. Treble is smooth with decent air; not super sparkly and there’s no EST “sauce,” but it stays clean and non-fatiguing.

As a package, MK2’s standout is the low-end texture—thunderous yet controlled—making it one of the more engaging bassy sets under four figures. Technical performance is solid for the tier, though some rivals at lower prices bring more raw detail and EST extension. Build and accessories get a tasteful, modern refresh. For best balance, the stock tips work well; bass-boosting or treble-opening tips can shift it toward a more V-shape at the expense of overall smoothness.

On genre fit, MK2 shines with hip-hop, pop, EDM, and R&B, where its punch and warmth bring rhythms to life; for orchestral or leaner acoustic picks, the bass can edge forward depending on the mix. It scales to mid–high volumes nicely (around the 70–80 dB zone) without turning sharp. Compared with the OG RSV—now likely affected by a silent retune in recent units—the MK2 is the safer buy: less shout, more authority down low, and a broader all-rounder appeal. Recommended, especially if found below full MSRP, for listeners craving tasteful bass with natural mids and relaxed, smooth treble.
