DT 1990 Pro MK II vs Beoplay HX
impedance을 나란히 비교합니다.
impedance 이해하기
Impedance determines how much voltage is needed to drive a headphone to a given volume.
Categories
- 16–32 Ω — IEMs, most consumer cans. Run loud from a phone.
- 32–80 Ω — premium portable headphones. Phone works; dedicated amp adds headroom.
- 150–250 Ω — studio/Hi-Fi (DT 770, HD 600 family). Need a real amp.
- 300–600 Ω — pro studio. Definitely need an amp.
Why high-impedance exists
Higher-impedance drivers can be wound with thinner wire, allowing tighter motor systems and more accurate transient response — at the cost of needing more voltage to drive.
Sensitivity matters too
A 32 Ω headphone at 85 dB/mW sensitivity may be quieter than a 300 Ω one at 110 dB/mW. Always read impedance + sensitivity together.
이 매치업DT 1990 Pro MK II's 250Ω is roughly 1090% higher than Beoplay HX's 21Ω (a 229Ω gap). Whether that gap is noticeable depends on workload — small percentage gaps rarely change day-to-day experience, while gaps of 20% or more usually do.
impedance이란?
A headphone's electrical resistance to AC current, in ohms (Ω). Low-impedance (16–80 Ω) headphones run loud from any phone; high-impedance (250–600 Ω) need a dedicated amplifier.
