TRN Mermaid earphones 1BA+1DD+2Planar Hybrid driver Headset In-Ear Monitor Hi-Fi Headphones

The TRN Mermaid hybrid IEMs combine a 1 BA + 1 dynamic (glass diaphragm) + dual 6mm planar/microplanar driver stack and come with a robust accessory set (crush-resistant case, USB-C dongle, ten ear tips). They’re easy to drive from phones but have a fixed heavy ribbon cable and large resin shells that can weigh down the housing and affect portability — great for listeners who want controlled bass, clear mids and airy treble, less ideal for those needing a lightweight, modular setup.
