Nice to see more companies taking this kinda concept seriously (altho if concerts weren’t obnoxiously loud it wouldn’t be necessary :D )
I wonder if some headphone reviewers will be able to measure the FR of these vs competitors like Vibes and Etymonic
Small version with 2 different filters ~40€, big version with 4 different filters ~80€. All come without any kind of carry case / pouch. A bit expensive and lacking for that price tbh
