Blue's Mix-Fi is the first headphone that combines a built-in custom audiophile amplifier and 50 mm, fiber-reinforced dynamic drivers, delivering the most accurate sound reproduction you've ever heard, on every device, from studio gear to laptops, tablets, and your phone. The unique multi-jointed design and sealed earcups result in a level of fit and comfort that just isn't possible on other headphones. Plus it creates a perfect seal, resulting in solid bass response, improved isolation, and reduction in bleed - perfect for tracking in the studio. Mix-Fi includes three all-analog amp modes so you can choose the right sound for your music.
