Lime Ears Incognita VS Fir Audio E10

Youtube Video Summary

Lime Ears Incognita arrives as part of the brand’s Power Trio with Terra and Maris, carrying a $1,700 tag and build that feels suitably premium. The shell isolates well, grips tips securely, and wears a striking, lava-flecked faceplate; the leather case looks and feels durable. The included cable on this sample appears non-final but is notably supple and well-behaved.

Sonically, the tuning hits that sweet overlap of impactful, detailed, and lively. Bass is rich and thick yet controlled—elevated without turning the mix muddy—while a tasteful dip around 4–5 kHz keeps upper energy in check and contributes to an easy, coherent tonality. Versus Terra, Incognita trims some “sparkle/air,” yielding a slightly more bass-forward and less fatiguing listen that still carries incisive detail and a fun swing.

Comparisons underline the balance: “graph twins” like the Jazier 61T can look similar but don’t match the Incognita’s resolution and texture; Truthear Nova and Binary Dino Quattro bring more upper-air energy with quirks; EM10 reads more V-shaped; Dunu Glacier impresses but can come off a bit shouty. At a similar tier, Symphonium × Elysian Europa trades blows, while Acoustics Lab Apostle offers extra sparkle and mid focus—Incognita counters with fuller low-end weight and a slightly V-leaning balance. With excellent fit, strong isolation, and a tuning that stays engaging without fatigue, Incognita stands out as a fantastic all-rounder that warrants a serious demo for veteran listeners.
