Blue has been in the business for two decades making some of the best microphones on the market. This week they unveiled Mo-Fi ($350), their first step, nay, leap into the headphone market. Mo-Fi is the first headphone to combine a built-in audiophile amplifier and ultra-premium drivers that produce high-fidelity performance on any device.

“Until now, the only way to get a high-fidelity experience was to use expensive audiophile headphones tethered to a bulky amplifier—not the way most of us want to listen,” said John Maier, CEO of Blue. “Mo-Fi changes all that, with a built-in audiophile amplifier that delivers the power and quality of a hi-fi system—inside your headphones. With Mo-Fi, we’ve brought a high-end listening experience to the mobile world we all live in. In fact, the concept is so simple and elegant, we couldn’t believe that it hadn’t been done before. So using that concept, we set out to design a headphone that would live up to the innovation Blue is known for.”

Unlike other headphones that go a bit too heavy on the base, Mo-Fi delivers an unparalleled listening experience by offering the user three amp settings: On, On+, and Off. When switched to On, you get powerful, detailed sound. On+ utilizes the amp’s analog low-frequency to deliver deep and smooth base. Off turns Mo-Fi to passive mode, good for connecting to a home A/V receiver that already has high-output amplification.

Lastly, Blue developed Mo-Fi’s headband and earcups from scratch. Straying away from traditional headphone design, Blue invented a multi-jointed headband that provides comfort and adjustability for various head shapes and sizes. The earcups are shaped like ears, improving the isolation and providing the best seal for solid bass, all while reducing sound bleed.
