Version Without Mic With Mic

The TRN Shell is a wired hybrid in-ear monitor with four drivers per side (10.5mm beryllium-plated, 8mm PET and 6mm titanium-plated dynamic drivers plus a 6mm planar), three screw-in tuning nozzles and a liquid-metal shell. It suits listeners stepping up to a multi-driver IEM who want adjustable tuning and a 4.4mm balanced plug option, with or without an inline mic.

Who the TRN Shell is for

Multi-driver setup: Three dynamic drivers share the range while a 6mm planar driver handles the ultra-high frequencies, per TRN.
Tuning by nozzle: Three gold-plated brass nozzles (Transparent, Reference and Atmospheric) screw on to shift the balance.
Balanced sources: Swappable 3.5mm and 4.4mm plugs fit single-ended dongles and 4.4mm balanced outputs.
Finding a seal: 13 pairs of ear tips in five styles, including memory foam, come in the box.
Calls and voice chat: The With Mic version adds an inline mic on the cable.
Skip it if: You want wireless listening or active noise cancelling; the Shell is a wired, passive IEM.
