Our take

 

A bass-forward tribrid IEM with electrostatic super-tweeters — physical weight and rumble, kept smooth on top.

 

This is for you if: You want the Mega5EST's smooth, refined sound but with real sub-bass weight underneath.

Look at other IEMs if: You want strict neutrality or a lean, reference low end. Then the standard Mega5EST is your pick.

How it's designed

  • Build: Ergonomic resin shell.
  • Comfort: Comfortable and ergonomic for long sessions.
  • The specs:
    Drivers: 1DD + 2BA + 2EST
    Impedance: 24 Ω
    Sensitivity: 101 dB/mW
    Distortion: 0.5% ±0.1%

What we hear

  • Bass: Deep and physical with a clear sub-bass lift — weight and rumble you feel.
  • Instruments: Full and weighty, riding on the bigger low end.
  • Vocals: Clean and present, sitting just above a fuller low end.
  • Treble: Airy and smooth from the EST tweeters — never crosses into harsh.
  • Details: Very good — resolving and clean despite the extra bass.
