AUDIO / QUICK REFERENCE

Headphone impedance is not enough to choose amplification

A plug fitting and a verified listening level are different questions.

Headphone impedance is not enough to choose amplification

A plug fitting and a verified listening level are different questions.

QUICK ANSWER

Ohms alone do not tell you whether headphones will reach the level you need. Impedance, sensitivity and the source output capability need to be considered together.

ADAPT THIS GUIDE

Check headphones and source without looking only at ohms

Impedance is only part of the problem. Source, sensitivity, target level and volume headroom also matter.

0 / 4 decisions
What is powering the headphones?
Do you know the nominal impedance?
What happens in practice?
Do you have the exact headphone and source models?

Impedance is one parameter

Headphone sensitivity and the output capability of the source also affect achievable level.

Use the exact variant

Different impedance versions of the same headphone family can require different electrical treatment. Keep the precise model in the setup.

Separate connection from numerical proof

If the necessary output data is unavailable, state that the connection is known while the target listening level remains unverified.
