Our Verdict

Beyerdynamic DT 990 PRO

Sennheiser HD 599

The Beyerdynamic DT 990 PRO and the Sennheiser HD 599 are both great headphones for audiophile use. The HD 599 are more comfortable for long listening sessions, while the DT 990 PRO are noticeably better-built and feel more durable, but have a tighter fit. Also, while both their sound profiles are very similar, the HD 599 may sound slightly more open than the DT 990 PRO. The DT 990 PRO come with a non-detachable coiled cable while the HD 599 come with two thin and detachable audio cables.
