m20 Apex Module

Swapping in this module noticeably rounded off the sharp edges in the upper frequencies without losing detail. It clicks into the housing just as firmly as the stock piece, so I'm not worried about it loosening up.

I grabbed this module to tame the treble on my in-ears and the difference is night and day. The isolation stays intact and I can actually listen for hours without that sharp fatigue creeping in. Installation took seconds, which I appreciated.

Swapped in the m20 and the bass finally has real weight behind it without muddying the mids at all. It's a small module but the difference in low-end presence is genuinely noticeable on bass-heavy tracks.
