Mo-Fi stands for "true mobile high fidelity." From your studio gear to your laptop and even your phone, the built-in audiophile amp and perfectly matched precision drivers provide articulation and huge dynamic range from device to device. Mo-Fi's amp removes the burden of power from your mobile devices, so they can pass audio at their optimum output levels-this means that you are always tapping into the highest possible audio quality. With Mo-Fi, you get studio quality audio on any device, so you can track, mix and really enjoy your music anywhere.

Remember when studio monitors went from passive to active? Now it's happened to headphones. Mo-Fi brings the performance of custom-tuned, high-end reference monitors to your ears, so you can judge what's really going on in your mix. When you're making music, the built-in amplifier provides ample headroom, while the excellent sound isolation lets you hear the music clearly. It all integrates together to deliver astounding accuracy and detailed imaging, so you'll be able to create mixes on any device that translate across all systems.

Mo-Fi is no ordinary headphone. From the multi-jointed design to earcups shaped like ears, Blue has completely reimagined the form and functionality. The result feels less like a headphone, and more like a high-quality instrument you can wear.

The unique multi-jointed headband was inspired by the finely tuned suspension of an open-wheeled Formula One racecar. It's elegant. It's comfortable. And it features an adjustable tension knob that allows you to dial-in the perfect setting-not too tight, not too loose, but just right. Pivoting arms allow for a small change in the angle of the earcups to achieve a large amount of height adjustment. The earcups simply float into place. You get 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.

Unlike those bass-in-your-face headphones, Mo-Fi includes three amp modes so you can choose the right sound for your music. No DSP tricks here-this is all analog. "On" activates the audiophile amp, "On+" engages the amp's low-frequency enhancement circuit for exceptionally rich and smooth bass, and "Off" puts the headphones in passive mode if you're connected to high-output studio gear. No matter if you're tracking, mixing or just enjoying your music, you'll have total control over your listening experience.

Mo-Fi's smart design saves big on battery life, ensuring that the headphones are always ready for action. First off, Mo-Fi knows when you've stopped listening and automatically powers down to save juice. The battery will charge completely in 3-4 hours, and give you approximately 12 hours of life-changing playtime (with intelligent power management, that 12 hours will feel like forever). And even if the battery runs down, Mo-Fi can continue to work in passive mode.

More and more hi-resolution music is hitting the market. These incredible recordings allow you to enjoy all the details of the original tracks. But why listen to hi-res music with low-res headphones? Only Mo-Fi can faithfully reproduce these amazing recordings. So go Mo-Fi-and hear what you've been missing.

Blue Stepped into the Headphone arena and knocked it out of the park!

By Joseph

from Massachusetts

Comments about Blue Mo-Fi Powered High-Fidelity Headphones:

I have only had these for two days so far but they are one of the best headphones I have ever bought! I have owned Sennheiser, Shure (Earbuds) and various others, I am hard on my headphones as I use them almost every day. Just by holding them I can feel the quality and engineering that went into them. These are not your typical plastic and metal headphones, these things are made to last, Mostly metal and even though they are a bit heavy I do not feel it once they are on my head. They took the approach to these as what does the user want, not what can we put together. From the way they created the headband to the integrated amplifier for better sound, even allowing you to use them if the amp runs out of power took forethought on the user experience! If you look at the headphones resting on the desk they even took into consideration of the placement of the plugs, they don't impede them resting on the desk. The elongated plug that goes into the headphones shows they tested this and did not want to put strain on the jack so they recesses the input jack so the metal plug prevents the dreaded cord strain. They even integrated a shut off switch built into the headphones so if they are not on your head they are not on, again forethought on not letting the battery drain out when not in use. Now lets talk brass tax. These things sound awesome! weather it is with the amp or not and the extra bass boot is not overwhelming but defiantly a nice touch. When will I use them, working listening to music, Gaming playing my favorite MMO or even just using my iPhone relaxing at home. They do make everything sound better! Great Job Blue!

Comments about Blue Mo-Fi Powered High-Fidelity Headphones:

I primarily use headphones for listening to music while drumming. Also used headphones for iPod music/movie watching while traveling, they sound awesome! They are comfortable! The con is, the cords break very easily, have already ordered 2 new cords from Guitar Center, cost for shipping was way too high for new cords that shouldn't have to be replace after a couple of weeks of use. Top of headphones were adjustment is for tension not screwed into the top piece, it just fell off. When I investigated, screws resting in padding for head. For what I paid for Mo-Fi this should not be this way. NOT HAPPY about construction and quality control at this point. I would expect these issues with sub-standard quality products. Makes no difference how great they sound if they fall apart before they are used.
