The MM2 shell body is made of eco-friendly resin and has aluminum alloy faceplates. The faceplates are faceted and have a matte finish. You probably noticed the circular vents on the faceplates, which are the tuning valves. There are 3 sets of valves (Bass, Balanced, and Treble) and they’re straightforward to change by simply unscrewing and screwing in the new set.

Gear used for testing includes the SMSL D-6 DAC with the Feliks Audio Echo, the Cayin RU6, and Shanling M5s.

With the gold valves in place, the MM2 has a V-shaped signature. It has an elevated bass, recessed mids, and bass.MM2 has some big bass. It could even be called a bass head IEM. Both the mid-bass and sub-bass are elevated and delivered with gusto. It’s not the fastest bass and there’s some bleeding into the midrange but it’s a relatively fast and quite fun bass.
