Our Verdict
Sennheiser HD 650
HiFiMan Sundara 2018
The HiFiMan Sundara 2018 are better headphones for neutral listening than the Sennheiser HD 650. The HiFiMan get more bass and perform more consistently in the treble range. They also have a more impressive soundstage and are more comfortable, but there have been reports of quality control issues with the brand, so the Sennheiser is still a good choice too.
