AKG K371 vs HiFiMan HE400se

Depending on your usage, you may prefer either the AKG K371 or the HiFiMan HE400se. The AKG are closed-back headphones, which are well-suited for listening sessions where you want to block out background noise and reduce audio bleed. They also have a more bassy low-end, which some users may prefer. However, the HiFiMan are open-backs, which are designed to let sound escape the ear cups in order to create a more immersive soundstage. They're more comfortable, better built, and are able to reproduce audio more consistently on different people.
