Blue Mo-Fi Headphones – Review
There may be a surfeit of headphones on the market, but there are still ways for new products to break through the clutter. Blue Microphones has always been best associated with professional audio recording equipment, but the company’s Mo-Fi headphones should not be overlooked. Take out your smartphone, please, because these headphones are something to text home about.
Included in the box with the Mo-Fi are a soft carrying case, 1.2-meter audio cable with audio and phone controls, a longer 3-meter cable without the controls, and a 1-meter micro USB charging cable, for use in charging the 1020 mAh onboard battery. Unfortunately, the detachable audio cables cannot easily be switched out with generics should they fray; the port on the headphones lies deep within the plastic frame and can only be reached by an extra-long 3.5 mm plug.
Before even placing the Mo-Fi around my ears, I quickly came to the conclusion that not only was it the largest headset in my collection, but also the heaviest at just over one pound (16.44 oz), due largely to its high-strength plastic and aluminum construction. While the Mo-Fi’s beefy size does make it less suitable for travel, audiophiles should not dismiss the headphones – what the Mo-Fi lacks in portability, it more than makes up for with its exceptional audio quality, and sheer ruggedness.
The Mo-Fi fit snugly and comfortably over my ears, blocking out much of the environmental sound, even without music playing. While it does not feature noise-canceling technology, the tight seal keeps audio isolated within the ear cups, and the onboard amplifier successfully drowns out unwanted sound. Over an extended period, I noticed a bit of pressure from the comfortable ear cups against my mandible – a minor discomfort, but nothing unbearable.
Music sounds clear through the Mo-Fi headphones, and switching the onboard amplifier to “on” boosts the audio presence, beyond just raising the volume. Turning the knob further to “on+” delivers a “turn it up to 11” effect – an audible “wow” escaped my mouth when I listened to the layered animalistic chords in Pink Floyd’s Pigs. Better yet, the vocals never sounded shrill or canny, coming through with rich and deep clarity. While many headphones with built-in drivers and amplifiers simply boost the bass, each range of the Mo-Fi’s frequency shone through without being overpowered by thumping beats.
With an output of 240 mW, I could set my device’s volume at 1/4 of the capacity for comfortable listening. But the Mo-Fi’s 50 mm dynamic driver – which is just about the largest driver to be found in commercial headphones and features an impedance of 42 ohms and a frequency response of 15 Hz-20 kHz – is what’s largely responsible for making the audio tracks to sound their best. Even passively, Mo-Fi delivers a balanced and pure sound, but whenever I engaged the onboard amplifier, I found that tunes leapt right out, popping brilliantly and creating an immersive experience.
Each song seemed to be uniquely enhanced by the Mo-Fi’s amplifier and driver – when I listened to Red Hot Chili Pepper’s Around the World, I noticed the bass guitar come to life for the first time. In The Strokes’ Machu Picchu, however, the Mo-Fi lent a helping hand to the quiet mid-level guitar, leaving the bass where it belonged. The Mo-Fi even managed to breathe new life into the few songs in my library with bitrates under 128 Kpbs.
Blue’s Mo-Fi is one of the most impressive sounding set of consumer headphones I have come across on the market. While their size and weight render them unfavorable for light travel, the undeniable audio quality could earn the Mo-Fi a spot in your home entertainment setup.
