BTS member V said after the group performed in Baltimore on Tuesday that he has been receiving treatment for hearing difficulties for more than two years. “If the hearing in my left ear is at 100, it’s only about 30 in my right,” he said. Jungkook also disclosed a shin injury that has restricted his movement during the group’s North American tour. BTS is on the North American leg of its new “ARIRANG” world tour. The North American leg follows a series of European concerts in cities including London, Paris and Munich.
