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
7Hz Salnotes Zero:2
- ✓Reference-grade 'neutral with bass boost' tuning rare at any price

- ✓Detachable 0.78mm 2-pin cable, with 3.5mm or USB-C and mic options
- ✓Light, comfortable shells for long sessions
- ✓Runs adequately from any phone or laptop jack
- ✗Short nozzles make a good seal genuinely hard for some ears — tip-rolling likely
- ✗Plastic shells and basic cable look and feel their price
- ✗No carry case or accessories beyond ear tips
- ✗32-ohm impedance wants a touch more volume than sensitive rivals
- ✗Bright colorways aren't for everyone
