People whose ears opened — from the 12-person experiment to a neurologist

👥Scenes lifted from the records

Different in age, job and starting line — there was individual variation, but the ears of a person who kept at it changed without exception.

• 5th-grader*Zootopia* comprehension 20–30% → 70–80% after a month. Changed the KakaoTalk profile to “I’m happy.”
• 3rd-graderOssam’s nephew, who was behind in school — after 3–4 months of 4× shadowing, began to hear the adult cartoon *The Simpsons*.
• Businessman in his 60sListening stuck for 10 years doubled in a month. His hearing age grew much younger, and he came to turn the TV volume down.
• Labor attorney / tax accountantProfessionals whose email English was perfect but who couldn’t hear phone calls — after two months, their TOEIC LC jumped. One left a review: “I did it roughly — how it goes up is a mystery.”
• Export-company CEOSomeone who always brought an interpreter pulled off a meeting with a UK partner alone, and posted a review on social media out of sheer joy.
• US doctoral studentAn international student who could read papers but couldn’t catch a professor’s fast speech — after a week of intensive training, “clearly different.”

🧑‍⚕️A neurologist’s endorsement

The neurologist Dr. Shin Dong-seon trained for a month himself, opened his ears, and left an endorsement on his blog — that “this is not a mere academy but neural training.” Real-name student reviews are published, unedited, on the Naver blog.
