Understanding THD+N: Total Harmonic Distortion Plus Noise

When evaluating audio equipment, you may encounter the term THD+N, or Total Harmonic Distortion plus Noise. This metric is crucial for understanding the quality of sound produced by headphones.

### What is THD+N?
THD+N measures the amount of distortion and noise present in the audio signal compared to the original sound. It is expressed as a percentage, with lower values indicating better sound quality. A THD+N of less than 1% is generally considered good.

### Importance of THD+N in Headphones
High-quality headphones should produce sound that closely matches the original recording. High THD+N values can lead to muddiness, loss of detail, and overall poorer sound quality.

### Ideal THD+N Levels
- For Audiophile Headphones: Aim for THD+N levels below 0.5% for the best listening experience.
- For General Use: Levels below 1% are acceptable for most casual listeners.

### Conclusion
Understanding THD+N can help you make informed decisions when choosing headphones, especially if you are an audiophile seeking the highest sound fidelity.
