Pros & cons
Koss KSC75
- ✓Class-leading clarity and openness for around $20
- ✓Titanium-coated drivers with a wide, airy presentation
- ✓Roughly 43g — effectively weightless, no headband hair
- ✓Runs from any phone or laptop jack (60 ohm, 101 dB/mW)
- ✓Koss limited lifetime warranty
- ✓Massive mod community — headband and pad swaps are cheap and easy
- ✗Ear-clip design takes fiddling and bothers some ears until you mod a headband on
- ✗Zero isolation and full sound leakage — home/desk use only
- ✗Bass is tight but shallow; no sub-bass to speak of
- ✗Bright upper mids/treble can fatigue sensitive listeners
- ✗Build quality is as cheap as the price suggests
- ✗Fixed cable
Moondrop Chu II
- ✓Standard 0.78mm 2-pin detachable cable — the original Chu's dealbreaker, fixed
- ✓Dense zinc-alloy shells with build quality far above the price
- ✓Warm, safe Moondrop tuning that's easy to enjoy on any genre
- ✓18-ohm / 119 dB sensitivity needs zero amplification
- ✓Ships with Moondrop's well-liked Spring Tips
- ✓Tiny shells fit most ears comfortably
- ✗Bassier and thicker than the original Chu — less clean than rivals like the Zero:2
- ✗Included cable is thin, springy, and tangle-prone
- ✗Metal shells add a little weight and cold-touch in small ears
- ✗Average isolation for a sealed IEM
- ✗No mic on the standard version (the Chu II DSP variant covers that)
