Beyerdynamic DT 990 PRO
Beyerdynamic DT 900 PRO X
The Beyerdynamic DT 990 PRO and the Beyerdynamic DT 900 PRO X are similarly performing audiophile headphones with different strengths. While both headphones are comfortable and well-built, the PRO X have a different driver design that's advertised to reproduce loud sound without distortion, whether connected to an amp or a smartphone. They also have a wider and more out-of-head passive soundstage. However, the 990 PRO's mid and treble responses are more balanced, whereas the 900 PRO X features some dips in the low-mid and low-treble ranges that can impact their clarity. They 990 PRO use a coiled audio cable, but it isn't detachable.
