Na \u00e9poca, a Koss era sin\u00f4nimo de fones de ouvido e provavelmente a n\u00famero um no mundo. Visitei a Koss em 2003 e n\u00e3o s\u00f3 fui muito bem recebido pelo fundador John e o seu filho Michael como sa\u00ed de l\u00e1 com v\u00e1rios fones na m\u00e3o! Michael Koss Jr., membro da terceira gera\u00e7\u00e3o da fam\u00edlia que controla a empresa, nos concedeu uma interessante entrevista, <strong><a href=\"http:\/\/revistahometheater.uol.com.br\/portal\/2018\/04\/18\/entrevista-exclusiva-como-nasceu-o-fone-de-ouvido\/\">que pode ser vista aqui<\/a><\/strong>.<\/p>\n<p>O fone over-ear Koss Porta Pro foi lan\u00e7ado em 1984 e se tornou um cl\u00e1ssico, tendo inclusive sido adotado por m\u00fasicos profissionais de diversos estilos na monitora\u00e7\u00e3o de palco.
