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.

Con:Midrange can feel slightly recessed or thin
