Testimonials
Real people, real ears, real talk
“I spend 12 hours a day mixing tracks and honestly thought my ears were invincible. Spoiler: they're not. Bloop keeps me in check so I can still hear my own music at 60.”
David X.
Award-Winning Music Producer
“When you're crushing a workout, it's way too easy to crank up the volume. Bloop taps me on the shoulder before I accidentally blast my eardrums into retirement. My forehand is still mid, but at least I can hear the ball.”
Yiran H.
Semi-Professional Tennis Player
“Between subway screeches and honking cabs, my headphones were working overtime just to compete. Turns out I was slowly becoming the guy who yells into his phone. Bloop saved my ears—and my dignity.”
Kaien H.
Average New Yorker
