Frequently Asked Questions

The HD-400 Pro offers a more refined and detailed soundstage compared to the HD 300 Pro, with a slightly more neutral presentation overall.
They're certainly capable, but consider your preferred sound signature; some mastering engineers might prefer a more colored headphone for final listening.
While they'll work with a standard headphone jack, a dedicated amp will provide more headroom and potentially reveal even more detail, especially with higher-end sources.
