In 1984 we created the Porta Pro® Headphones to be the ultimate portable pair of headphones that last a lifetime. The Porta Pro® remains one of the world’s most popular on-ear portable headphones, after 34-years. Our Design and Engineering Teams collaborated to make one of the world’s most iconic headphones – wireless – while maintaining The Sound of Koss® acoustical signature that Porta Pro® fans have cherished for more than 34-years. The new Porta Pro® Wireless Bluetooth® Headphones takes the classic Porta Pro® Sound, and adds more control, freedom and portability.
