Generation & platform

The scores rank quality. This is the other question: is the newer one actually newer technology, or the same platform in a new shell?

Same generation

Hidizs MS2 PRO (2025) against TRN Medusa (2024). These are the same generation of hardware - nothing in the radio, the codecs or the noise cancelling separates them. Nothing separates them on convenience features either, so the choice comes down to tuning and price.

What reviewers said

Hidizs MS2 PRO

The Hidizs MS2 PRO is a budget-friendly hybrid IEM pairing a 10.2mm dynamic driver with a custom balanced armature for a bass-forward yet technically capable sound. It offers adjustable tuning via included nozzle filters, letting you tweak the response to taste, while its comfortable, well-built shell and detachable cable add everyday practicality. Though engaging and versatile for the price, it has a slightly recessed midrange and can sound bright or sharp in the upper frequencies on certain tracks.
