With premium materials, clear and detailed sound, and surprising dynamic performance, it shows real potential... but it's not without its flaws. In this video, I break down the tuning, comfort, sub-bass issues, and how it stacks up against the HiFiMAN Arya and Meze 105 AER. Is it worth backing on Kickstarter? Let's find out.

Fosi traced the issue to sound leakage from the Velcro-mounted earpads. Their fix? A new sound-isolating ring around the diaphragm and it works! Sub-bass is finally back, as expected.
