TRN MERMAID In-Ear Monitor

A 10mm dynamic driver IEM with a detachable 0.78mm 2-pin cable, available in 3.5mm single-ended and 4.4mm balanced configurations—crafted for listeners who want expressive, musical sound with the flexibility to upgrade their cable.

The TRN MERMAID is a single dynamic driver in-ear monitor designed to deliver a rich, engaging, and musical listening experience. At its core is a 10mm dynamic driver tuned for a full-bodied sound signature with extended bass, natural midrange presence, and smooth treble extension. The 0.78mm 2-pin detachable cable system allows easy cable swaps and upgrades, while the choice of 3.5mm single-ended or 4.4mm balanced termination ensures compatibility with a wide range of sources. Available in two distinctive colorways—Green and Purple—the MERMAID combines expressive aesthetics with genuine audiophile performance at an accessible price point.

Key Features

• 10mm Dynamic Driver — Full-Bodied, Musical Sound: The MERMAID is built around a carefully tuned 10mm dynamic driver that delivers a warm, engaging sound signature with impactful bass, natural midrange, and smooth treble. Dynamic drivers excel at conveying the organic texture and weight of instruments that multi-BA setups can sometimes lack.
• 0.78mm 2-Pin Detachable Cable — Upgrade Flexibility: The industry-standard 0.78mm 2-pin connector system allows the stock cable to be swapped for any compatible aftermarket upgrade cable, giving you full control over your sound and ergonomics without replacing the IEM itself.
• 3.5mm & 4.4mm Termination Options: Choose between a standard 3.5mm single-ended cable for universal compatibility, or a 4.4mm balanced cable for use with balanced-output DAPs and amplifiers—delivering lower noise, higher channel separation, and increased output power.
• Distinctive Green & Purple Colorways: The MERMAID is available in two expressive colorways—a vibrant Green and a deep Purple—each with a unique shell finish that stands out from the crowd while maintaining a comfortable, ergonomic over-ear fit.
• Ergonomic Over-Ear Shell Design: The contoured shell is designed for extended wear comfort, with a lightweight build and smooth edges that sit securely in the ear during long listening sessions or commutes.
• Wide, Immersive Soundstage: The 10mm dynamic driver configuration and tuned acoustic chamber produce a wider-than-average soundstage for an IEM at this price point, with good instrument separation and a sense of space that rewards critical listening.
