Onboard amplification, for impressive monitoring accuracy

Remember when studio monitor speakers were passive? No great loss. Active speakers have done wonders for monitoring accuracy. And so it is with Blue Microphones Mo-Fi headphones. With an audiophile-quality onboard amplifier and perfectly-matched precision drivers, Mo-Fi has revolutionized monitor headphone design, delivering output that's stunningly true to the input, for studio-grade sound - even on your mobile devices. If you want to pump up the bottom, though, Mo-Fi gives you an enhanced bass mode (along with active and passive settings), so you can optimize any listening situation. Headphone design will never be the same.

You control the bass

Unlike other headphones that put more bass in your face whether you want it or not, Mo-Fi lets you choose the right sound for your music. No DSP tricks here - this is analog. No matter if you're listening to '70s-era rock, modern pop, orchestral, hip-hop or something else, you'll have total control over your listening experience.

Sound that's way beyond earbuds

If you're listening to music on your iPod, iPhone, or another personal music player, you're missing out on the full dynamic range and frequency response of the music. These underpowered devices simply can't drive a strong enough signal through earbuds. That's where the Mo-Fi's integrated amplifier comes in. It delivers an astonishing listening experience that you have to hear to believe.

Ergonomic fit gives you cushy comfort during marathon sessions

Mo-Fi is no ordinary headphone. From a technical standpoint, Mo-Fi's a game changer, but when you first try them on, you'll be thrilled that Blue Microphones paid just as much attention to their physical design. From their innovative multi-jointed design, to earcups shaped like - well, ears, Blue has thoroughly reimagined headphone form factor and functionality. Blue fitted Mo-Fi with a multi-jointed headband, earcups that ergonomically float into place, and an adjustable tension knob that lets you effortlessly dial in your ideal "Goldilocks" setting - not too loose, not too tight, but "just right." Mo-Fi gives you extreme comfort that other headphones simply can't.

Smart power management means Mo-Fi's always ready for action

Mo-Fi's intelligent design saves on battery life, ensuring that your 'phones are always ready for action. Mo-Fi knows when you've stopped listening and automatically powers down to save juice.
