Our Verdict
HiFiMan Edition X
Sennheiser HD 820
The HiFiMan Edition X are a better critical listening headphone overall when compared to the Sennheiser HD 820. The HifiMan are better balanced throughout their entire response and cater well to instruments and vocals, sound clear, and have enough bass for most tracks. However, the Sennheiser have a closed back design, which means they isolate more and leak less. The Sennheiser have slightly more bass and a much more premium and durable build quality than the HiFiMan. They're also slightly more comfortable and come with more accessories and cables.
