Softears Enigma VS Unique Melody Mason FS Soleil Tomb

The Softears Enigma is a flagship tribrid IEM using a 12-driver array (2DD+6BA+4EST) with a hybrid 5-way/4-way crossover and an aluminum shell; the package also includes a premium Effect Audio cable. Street pricing centers around $3,699 USD and multiple reviews note the surprisingly comfortable fit despite the larger shells.

Tonal reports describe a warm-leaning, neutral-with-bass-boost balance: essentially an RSV-like midrange with extra low-end weight and smooth lower treble, extending well up top. Show impressions from Precogvision characterize it as “RSV with a dynamic driver and some extra bass,” which aligns with long-form reviews calling the Enigma warm, full, and balanced rather than aggressive.

Technical performance is a strong suit: reviewers note clean separation, high detail retrieval, and stable imaging; the EST tweeters can benefit from capable sources, while isolation is average. Factoring in its high MSRP, the Enigma’s execution is impressive but its value proposition is challenged by lower-priced alternatives (including Softears’ own RSV) that deliver broadly similar tonality at a fraction of the cost.

The Unique Melody Mason FS Soleil Tombé delivers a neutrally balanced sound signature characterized by a smooth, analog-like tonality across lows and mids, paired with naturally resolving treble. Its bass presentation stands out with deep extension and textured rumble, leaning toward mid-bass emphasis for a fuller, warmer impact that defies typical BA limitations—thanks partly to the innovative BC-Turbo Micro Booster enhancing the FreqShift bone conduction driver. This results in cohesive bass-to-mids integration without bloat, while upper mids maintain clarity and vocal forwardness.

Technically, the IEM excels with an expansive soundstage that stretches proportionally in width, depth, and height, though layering and separation prioritize blend over surgical precision. Its imaging remains accurate, placing instruments and vocals holographically—a trait amplified by the included First Times Shielding Pro cable, which deepens background blackness and enhances spatial cues. Source pairing is critical: warmer DAPs like the Cayin N30LE (Classic Tube/Class A) elevate its organic texture, while leaner sources may skew treble energy.

Tonally, the Soleil Tombé shines with natural timbre and richness, particularly in acoustic genres like jazz or classical, where its textured bass and organic mids convey instruments authentically. However, its laidback decay and subdued treble air make it less suited for EDM or highly synthetic tracks demanding razor-sharp transient speed. While tip selection can fine-tune bass weight (Symbio W tips heighten detail retrieval), the IEM’s coherence and non-fatiguing profile cater to extended listening—despite its steep price.
