Uniquely designed to blend with on-the-go lifestyles, the MTRO series delivers big beats and big sound for when you're on the move. Made to deliver an immersive music listening experience, our MTRO in-ear headphones have a potent 8.6mm speaker driver while MTRO over-the-ear models feature a powerful 32mm driver. Together with a well-engineered sound chamber, MTRO delivers powerful bass that not only adds another dimension to overall sound, but also lets you feel the music like never before. The integrated in-line remote lets you seamlessly control the music you listen to, receive or reject calls, and adjust volume as needed.
