Very dark sounding IEM. Very warm and thick. But decent treble extension.

Fun and bassy, v-shape, great low-end slam and texture, full, rumbly, solid tech imaging, and cool faceplate... but price is a bit high.

The FlipEars Legion makes a commanding entrance with its striking Roman legionnaire-inspired design, featuring jewelry-cast rose-plated brass faceplates hand-painted by master artisans in Bulacan, Philippines, ensuring each unit is a unique masterpiece. While the substantial resin housings may challenge smaller ears, the included Eletech Baroque tips and pliable cable contribute to a surprisingly secure and comfortable fit over time. Unboxing feels luxurious, with a premium leather case and meticulous packaging underscoring FlipEars' commitment to craftsmanship.

Sonically, the Legion leverages its innovative tribrid driver system to deliver thunderous, tactile bass via a custom dynamic driver and EarQuake bone conduction unit, creating visceral sub-bass rumble without muddying the midrange. The midrange remains lush and articulate, presenting vocals with natural warmth and instruments with rich texturing, while the SPARK electret tweeter adds refined, fatigue-free sparkle to the highs. This synergy results in a cohesive, immersive sound signature that prioritizes musical engagement over analytical sharpness, making complex tracks feel both powerful and nuanced.

Technically, the Legion punches above its price point, boasting a holographic soundstage with precise instrument placement and exceptional layering that rivals models costing twice as much. Its imaging is pinpoint accurate, rendering subtle ambient cues and dynamic shifts with effortless clarity, while the bone conduction driver enhances physicality and depth without sacrificing control. Though its bass-forward tuning might not suit treble purists, the Legion excels as a reference-grade all-rounder for those seeking technical prowess paired with relentless musicality.
