Review: Blue Mo-Fi Headphones

The Blue Microphones Mo-Fi headphones look and feel different to most headphones available. The big question is how they sound and how comfortable they are. G. W. Childs investigates.  

The perfect set of headphones is sort of a holy grail for manufacturers of fine audio products. After all, everyone has their own idea of what makes a great set of headphones. After years of creating hi-end audio products for the studio and the consumer, Blue has decided to step up with an offering that not only sounds wonderful, but truly sets itself apart from the rest.

Mo-Fi Fit

First, before we get to anything else, let's just talk about the aesthetics of the Mo-Fi headset. These are different. What struck me the most is just how much die-cast metal went into the body, earphones, and other portions of the headphone structure. Mo-Fi headphones are built like tanks. And, the design is something truly different. Really, in some ways, it's almost a complete revision of headphone design 101. The phones themselves have an angular mounting that swivels forward, instead of being pulled down. The end result is a pair of headphones that really should be able to fit almost any head. My head is pretty big (7 1/4 hat size) and Mo-Fi can almost double the size from my big old skull, when the phones fully bend outwards.

"In some ways, it's almost a complete revision of headphone design 101."

As you begin to open up a pair of Mo-Fis, the difference becomes apparent and continues to do so, with a first time listening experience. As you slip the phones on, the phones clamp on to your ears, as other portions of the spring loaded assemblies position themselves around your head. It's almost like a doctor's office visit, but in a good way—These things are comfortable. 


Here's a warning: Mo-Fi headphones are probably the loudest headphones I have experienced in a long time. You can run them without any batteries, period. In this mode, you get a basic pair of speakers. However, if you take the time to charge them with the included mini-USB cable via either USB to your computer, or directly to an electrical socket, you will quickly discover how loud and full these phones get. From the Off position, move the switch on the left phone up to On, and you get a boosted signal that sounds clean, full and definitely gives you a new take on any audio you run through Mo-Fi. Turn the switch to On+, however, and you had better turn the volume down.

On+ gives you a set of headphones that will match the volume levels asked for by some of the deafest musicians and producers on the planet. Bass is fuller, but not over the top, small signals that you normally miss, are completely amplified. I heard sounds via my Macbook Pro that I never even knew were there.


"The sound is just incredible."

Mo-Fi Headphones from Blue are masterfully created. You can tell A LOT of time went into the design, useability and above all sound. Two sets of cables are included. One cable with the iPhone interface built-in. The other cable, standard, for regular audio jacks, with additional adapters for every situation. 

The only thing I'd mention that you might want to watch out for is the weight. For me, they felt slightly heavy on my head. So, when using them, I tended to lay back in chairs that have a little neck support. The sound is just incredible, though. You will notice details in songs you've heard over and over again that you might never notice. And, while there technically is a 'Bass Boost' in the form of On+, the Mo-Fis are crazy flat in the regular On mode. The mix comes through just the way you left it. 

Price: $349

Pros: Amazingly innovative headphones that raise the bar on production, design and most of all, sound.

Cons: Slightly heavier than I'm used to. Great for the studio, possibly too big for headphone calls around the city.
