Our Verdict

Beyerdynamic DT 990 PRO

Drop + Sennheiser/EPOS PC38X

While the Beyerdynamic DT 990 PRO and the Drop + Sennheiser/EPOS PC38X are both great choices for neutral sound, the Drop are a better choice for wired gaming. The Drop have a boom mic to record your voice clearly, even in moderately noisy environments. They're also more comfortable and have a mic as well as volume controls. However, the Beyerdynamic are better built.
