Version

The TRN Conch is a wired in-ear monitor with a 10mm dual-magnetic-circuit dynamic driver using a DLC (diamond-like carbon) composite diaphragm, three interchangeable tuning nozzles and a detachable 2-pin cable with swappable 2.5mm, 3.5mm and 4.4mm plugs. It suits listeners moving up from stock earbuds who want to try different tunings, with or without an inline mic.

Who the TRN Conch is for

  • Trying different tunings: Three interchangeable nozzles (Reference, Translucent and Atmosphere enhancement) change the sound balance without changing earphones.
  • Phone and dongle listening: The 3.5mm plug connects to a USB-C dongle, a laptop or a portable player; TRN rates the Conch at 30Ω and 114dB.
  • Balanced sources: Swappable 2.5mm, 3.5mm and 4.4mm plugs connect the same cable to single-ended jacks and balanced DAP or DAC outputs.
  • Calls and voice chat: The With Mic version adds an inline mic on the cable; the Without Mic version keeps the cable plain.
  • Secure fit: Over-ear cable routing, the conch-shaped shell and seven pairs of tips, including a memory foam pair, help the earphones sit steadily.
  • Skip it if: You want wireless listening or active noise cancelling; the Conch is a wired, passive in-ear monitor with a single dynamic driver.
