Headphone Comparison Guide
Reference guide for headphone types, impedance, amplification, target curves, and EQ tips.
Frequently Asked Questions
- Do I need a headphone amplifier?
- It depends on impedance and sensitivity. Most IEMs and low-impedance headphones (16-32Ω) work fine from a phone. High-impedance models (250Ω+) or low-sensitivity planars typically need a dedicated amp.
- What is the Harman target curve?
- The Harman target is a frequency response curve developed through listener preference research. It features a slight bass boost and gentle treble rolloff, representing what most listeners find pleasing.
