For mixing and mastering, open-back headphones are typically the preferred choice, as they offer a natural sense of space and an uncolored representation of the frequency spectrum. The DT 900 PRO X delivers a particularly linear and precise sound image, making it ideal for these tasks. For those seeking maximum detail and resolution, the DT 1990 PRO MKII is a high-end option, offering excellent depth, clear bass, and detailed highs.
While models like the DT 990 PRO and DT 990 PRO X also feature an open design and outstanding spatial imaging, they are primarily intended for critical listening and precise editing, rather than tonal balancing during mixing.
As a closed-back alternative, the DT 700 PRO X is a strong candidate. Thanks to its linear sound tuning, it can also be used for mixing—especially in environments where open-back headphones are not acoustically feasible.
