HiFiMAN HE400i 2020 Edition Review

5.0

HiFiMAN's original HE400 turned a few heads in the headphone industry when it launched eight years ago. Since then, the design has been updated a few times, most noticeably with the release of the i-version. Today, we will have a look at the 2020 version of the HE400i. Despite the upgrades, it remains relatively affordable at $169.
