HiFiMan Sundara 2020 vs FIIO FT1

The HiFiMan Sundara 2020 are open-back audiophile headphones, while the FIIO FT1 are closed-backs, so they have different strengths. If you want headphones that interact with your environment for a more immersive sound, the HiFiMan are the better pick. However, you can't wear them in as many different sorts of places because they don't isolate and leak a lot of audio. They're also flatter and less bassy-sounding than the FIIO, which are warm-sounding with a deeper bass. While tuning comes down to taste, the notably more consistent frequency response on the HiFiMan ensures predictable sound between wears and people. Still, for a warmer, bassier sound and a comfortable fit that you can wear in more situations, the FIIO might be better, depending on your needs.
