Blue Microphones is famous for its high-quality microphones, and this company targeting high-end and professional music equipment is going to enter the headphone market. When a professional microphone manufacturer enters the headphone field, what sparks will the two collide? Let's take a look at Blue's masterpiece - Mo Fi headset.
Blue released a promotional video on the Internet. Surprisingly, there was no sign of Mo Fi in it. Instead, it made fun of people's listening habits today. In the eyes of Blue, those users who wear Apple Xiaobai and Magic Sound earphones can't be called "music appreciation" at all, but the past era of record player is the "correct way to open music". It can be seen that the audio of the Mo Fi headset has greatly changed.

Mo Fi Benefits
Built in high power fever power amplifier
50mm fiber strength dynamic unit
Closed ear muffs designed according to ear shape provide excellent isolation and feedback suppression
User adjustable tightness and suspension design, suitable for various head sizes
Multi point joint headwear inspired by sports cars keeps ear muffs always parallel and comfortable to wear
Fully analog power amplifier, three modes: passive, active and low-frequency enhancement
Automatically turn on and off the headset after it is turned on and closed
The rechargeable battery can work continuously for 12 hours, and can continue to work without power amplifier even when the power is out
Mo Fi Disadvantages
Due to its large size, Mo Fi earphones cannot be hung around the neck like other earphones because they are not only large, but also not light. For this reason, a portable bag is officially equipped.
There is significant RFI (line/radio noise). Some smart phones do not play music. (For example, LG G3) Of course, this problem can be avoided by switching the power amplifier mode of the headset.
The workmanship is a little rough. From the outside, it looks indestructible, but the internal parts are easily damaged.
The style is a bit unique, and I believe only a few people can accept it.
evaluating
The first impression when I saw the earphone was that it was too large and bulky, giving me a feeling of clumsiness. It weighs more than one pound. It can be said that Mo Fi earphones are the largest earphones in the market at present. Compared with Samsung's plusheriff ic, you can clearly feel it.
It is gratifying that the multi-point joint headwear design inspired by the sports car of Mo Fi can keep the earmuffs always parallel, and there is an adjustable knob on the headwear to let users choose their preferred pressure and tightness, at the same time, it can also get further sound isolation and reduce environmental noise. The wearer will not even feel that there is a "weight" of up to one pound on his head.
The reason why Mo Fi is so heavy is of course due to its metal structure. The connecting arm and folding arm seem to be made of stainless steel, which seems to increase the durability and strength of the headset. However, Mo Fi is a typical "tough on the outside, soft on the inside", and many structures inside the headset are through plastic hinges. This is the determinant of product durability.
The setting of the headphone jack of MoFi is relatively novel. We have to use the cable of Blue Microphones because the headphone jack of MoFi is not a standard 3.5mm stereo plug, but a 2.5mm 4-core jack is very rare.
There is a MoFi microUSB charging port and a small switch on the left headset. As a fairly normal person, you may think that this means that the MoFi wired and wireless headset play functions, but unfortunately, they are not.
Mo Fi provides three power amplifier settings: On, On+and Off. When On is selected, Mo Fi activates the power amplifier to provide powerful and detailed sound. The On+position allows the analog low-frequency enhancement circuit of the power amplifier to improve the low-frequency. Off file is to let Mo Fi connect to studio level equipment with high output in passive mode. This is why MoFis needs a charging cable.
MoFis is the only wired headset and is not used for noise reduction. It has a battery powered amplifier. "Why do you want a headset driver speaker?" This is the most critical question. The answer is just to make the music better. A music enthusiast may not ask such a question, because they know the advantages and disadvantages of analog audio.
Here is an example. The Nexus 5 headphone amplifier can provide a maximum power of 22.24 mW (32.46 mW for iPhone 5). This is enough to drive most earplugs, even for some low impedance earphones, there will not be too much distortion. MoFis is equipped with 240 mW amplifier. This is ten times the maximum power of the Nexus 5. Although this does not necessarily mean that its music distortion is one tenth of that of the Nexus 5, it means that it has a better music experience. Because MoFi provides their own amplification (with built-in power supply), so even if we adjust the external amplifier power of the headset, we can also bring excellent music enjoyment.
MoFis also has its defects. When connected to some specific devices, it will produce grating electronic noise. When the headset is adjusted to the on+power amplifier mode, LG's G3 mobile phone cannot recognize the headset device. This problem can only be solved by adjusting to other power amplifier modes. If you connect the headset to the Samsung S5, you will hear a slight "buzz" when you touch the screen.
The above problems will not occur when using MoFi headsets on Apple products, which may prove that Apple is more concerned about audio performance and compatible with third-party audio accessories than Android.
summary
Blue Microphones will The addition of high-power audiophile power amplifier to traditional headphones has undoubtedly improved the music experience to a higher level, making ordinary users jump out of the public listening habits, breaking this limitation, and on the other hand, meeting the needs of music enthusiasts.
However, the first attempt is not perfect. The earphone itself has many shortcomings. The plastic short board under the metal material and the huge volume undoubtedly reduce people's desire to buy. Audio compatibility needs to be improved. But at $350, compared with other audiophile devices, The performance price ratio of the Mo Fi headset is good.
