In order to let everyone know about dynamic+armature hybrid driver headphones, I must first popularize the difference between dynamic and armature headphones, and what are the advantages of the hybrid unit.
What is the difference between dynamic and armature headphones: dynamic and armature refer to the type of generating unit of the headphones.
Dynamic unit: A transduction mode of earphones, and most (about 60% or more) earphones currently belong to this category. The principle is similar to that of an ordinary speaker. The coil in the permanent magnetic field is connected to the diaphragm, and the coil drives the diaphragm to produce sound under the drive of the signal current.
Armature unit: uses an electromagnet to generate an alternating magnetic field. The vibration part is a piece of iron suspended in front of the electromagnet. When the signal passes through the electromagnet, the magnetic field of the electromagnet will change, so that the iron piece will vibrate.
Anyone who knows a little about headphones knows that the dynamic speaker has insufficient high-frequency resolution, and the armature speaker has insufficient low-frequency. The combination of the two makes up for their respective deficiencies.

Product Introduction
1. Charging cable
Mifo Fiitii Hifipods are equipped with a Type-C charging cable. Type-C charging cable has no directional choice, which is more convenient than Micro USB charging cable in charging operation. No charger is provided, you can use the charger of your Android phone or the USB port of your computer to charge the earbuds.
2. Silicone Eartips
In addition to a pair of silicone eartips pre-installed on the earbuds, 3 pairs of L/M/L eartips are also equipped. M eartips are pre-installed on the earphones, you can wear them first and change them according to the tightness and comfort of the wearing.
3. Charging Case
Mifo Fiitii Hifipods charging case uses 7 series aviation-grade aluminum alloy, which is the main material of the aircraft’s load-bearing components, with higher hardness and welding performance. The appearance of the charging case is the shape of a flying saucer, which gives the impression of being dreamy, fashionable, and full of technology. The surface fine teeth are arranged in concentric circles, which are smooth and comfortable to stroke along the lines.
Open the top cover, and the two earphones are embedded in the grooves of the charging case base. The surface of the black earphone shell reveals the light and shadow of black pearls, and the decorative design of the tortoise cracks shows the originality of the designer.
The Mifo Fiitii Hifipods charging case follows the design of the Mifo S, and the operation method of the earphone is printed on the inside of the upper cover of the charging case. This is an instruction booklet that goes with you, and will not be damaged or lost. If you forget the operation method, you can check it by opening the top cover.
In addition to opening the top cover, the open button can also restore the factory settings of the earbuds. The specific operation method is: put the earphones back into the charging case, and press the start button three times when the indicator light of the charging case is on.
Behind the opening button is the type-c charging interface. The Mifo Fiitii Hifipods charging case has a battery capacity of 1000mAh, and the charging time is about 2 hours. It can charge the earbuds 9 times, and the total battery life is about 70 hours.
There are three LED lights in the charging case, which can be used to know the remaining power of the charging case. You can predict the remaining power of the charging case based on the number of lights on.
5. Earbuds
Mifo Fiitii Hifipods earbuds have an in-ear design, and in-ear headphones are designed with silicone eartips on the filter, which can not only have the function of physical noise reduction, and the contact between the silicone eartips and the ear canal can reduce the foreign body sensation in the ear canal. The shape of Mifo Fiitii Hifipods earbuds conforms to the contour of the ear socket to the greatest extent, so it is comfortable, fit and stable to wear.
The earbuds use a hybrid sound unit, but the size of the headphones is not larger than the average single dynamic headphones. As far as I understand, Mifo Fiitii Hifipods earbuds use an 8mm dynamic driver and 2 balanced armature drivers. Anyone with a little headphone knowledge knows that the dynamic speaker has insufficient high frequency resolution, and the armature speaker has insufficient low frequency. The hybrid driver is to make up for their respective shortcomings.
I have experienced many bluetooth wireless headphones, most of which are dynamic headphones, and only a few are armature headphones, all of which are single sound units. Despite this, the longest battery life of the earphone is only 8 hours. The battery capacity of Mifo Fiitii Hifipods earbuds is only 55mAh, but it can be used for 7 hours in mild noise reduction mode, 5 hours in transparency mode, and 5 hours in strong noise reduction mode.
Operation of Earbuds
1. Bluetooth Connection
The earbuds use a Bluetooth 5.2 configuration. Open the top cover of the charging case, turn on the bluetooth of the mobile phone, search for the device name “Fiitii Hifipods” and click connect.
2. Touch operation of the earbuds
The earphone itself does not need to be turned on/off. Opening the top cover of the charging case will turn on the earbuds and connect to the bluetooth of the playback device. If you don’t want to use it or need to charge it, put the earphones back in the charging case and close the lid, and the earphones will turn off and charge.

Restore factory settings: Put the earbuds back into the charging case, and press the start button three times when the indicator light of the charging case is on.
Burn-in Earbuds
The sounding unit of the Mofi Fiitii Hifipods earbuds is a dynamic and 2 balanced armature drivers. If only balanced armature headphones can ignore the burn-in earbuds step. But it also has a dynamic unit, which requires burn-in earbuds.
The principle of burn-in earbuds is to make a rapid aging process of the mechanical system of the headphones, so that the edge of the diaphragm runs and the sound is not so tight, so burn-in earbuds are very necessary.
How to Burn-in earbuds:
Software: Download a software to burn-in earbuds with white noise.
Radio: Tuned to a place where there is no signal, the noise is also known as white noise.
Music: Play alternately with some light music and rock music, combine light and heavy, and play at low volume for a long time.
My favorite way to burn-in earbuds is the third way to burn-in earbuds while listening to music. There are a few points to pay attention to in this process: 1. Be sure to control the volume during the first 200 hours of use of the earbuds, preferably within 20% of the total volume. 2. During this period, be sure to selectively play songs, choose some light music and rock music to play alternately. 3. After 7-8 hours of playback, let the earbuds rest for 2 hours and continue (or recharge).

Bluetooth V5.2 version, in an unobstructed environment, the transmission distance is more than 20 meters. Battery life: The battery capacity of the charging case is 1000mAh, the total battery life is about 70 hours, and the earbuds can be charged 9 times. The battery capacity of the earphone is 55mAh, which can be used for 7 hours in mild noise reduction, 5 hours in transparency mode, and 5 hours in strong noise reduction.
In terms of calls: intelligent dual-mic call noise reduction, can resist the noise caused by 50km/h wind speed. In a noisy environment, the other party can still hear your voice clearly.
There were many doubts in the process of using the MOFI Fiitii Hifipods earbuds, so I consulted the staff of MOFI. Let’s sort out the content of our exchanges and present it to you in the form of question and answer, as a reference for friends who like MOFI Fiitii Hifipods.
Q1. Why does this earphones have the “FiiTii” logo?
A: FiiTii is MOFI’s new HiFi series of headphones.
Q2. What is the biggest difficulty in the design of this earbuds?
A: In order to achieve the sound effect of Mofi Fiitii Hifipods, the audio engineer spent 2 years of audio debugging. Among them, electronic frequency division technology processing, cavity design has become the biggest difficulty.
Q3. Why use electronic frequency division processing technology?
A: First of all, the earphone adopts 3 hybrid speakers, which is to solve the problem of insufficient high frequency resolution of dynamic speakers and insufficient low frequency of armature speakers. Three speakers must be divided into frequency processing.
There are two ways of frequency division: physical frequency division (passive frequency division) and electronic frequency division (active frequency division). Physical crossover is simple to operate, but has one major disadvantage. Once the crossover point is determined, it is not adjustable, and the relative cost is much lower. The electronic crossover is adjustable, and different crossover points can be adjusted according to the size of the audio, which can show a higher audio effect. However, it requires high frequency division processing technology, and at the same time, if the processing is not good, noise will appear.
Q4. I know that the dynamic driver of this headphone is 8mm. How did you make the 8mm dynamic speaker to make the 16mm dynamic speaker sound?
A: When I experience this earphone, its bass is very powerful. The bass effect it bursts out is definitely not what an 8mm dynamic driver TWS earphone can have.
The MIFO audio engineer used two solutions, one is the unique cavity design, so that the bass has a better resonance effect. Second, there is a rear cavity guide tube (equivalent to the inverted tube in the audio equipment), and the vibration sound wave behind the speaker is processed through the guide tube. Since the diameter of the guide tube is smaller than the diameter of the horn, there will be relatively strong sound waves rushing out of the guide tube. In this way, both the forward and rearward sound waves of the speakers are utilized, which improves the sound quality of the headphones. It is also driven by the resonance effect of the cavity, so that its bass resonance effect is brought into full play.
Q5. I have also used a lot of noise-cancelling headphones. Although both have noise cancelling functions, I feel that MIFO Fiitii Hifipods are different from other headphones. Is there any secret?
A: MIFO Fiitii Hifipods control the noise reduction depth within the range of 35-40dB, because this is the most comfortable noise reduction range for the human ear, it will not form a strong sense of air pressure, and at the same time, it will do a wider audio noise reduction. The so-called wider noise reduction audio means not only good low frequency noise reduction, but also high frequency noise reduction. Most of the noise-cancelling headphones on the market are within 800HZ, mainly for ultra-low frequency noise reduction of wind and breathing sounds. The noise reduction width of Fiitii Hifipods is nearly 2000HZ, and even loud voices have obvious noise reduction effects.
Sound Quality of MIFO FiiTii Hifipods
Listening to music with MIFO Fiitii Hifipodsearbuds, you can obviously feel that the sound quality is “thick” compared to other headphones. This “thick” is actually a feeling, and some people will also describe it as “concentrated”. Simply put, the high, medium and low frequencies of the earphones are stronger than other earphones. While enhancing, you can hear details that were previously not heard in those headphones.
When testing headphones, not all songs can be auditioned. You can choose some songs that are recognized by everyone as the main audition resources. After choosing these songs, you still need to listen repeatedly and carefully to master the nodes that can be tested. After a long time, there are more earphones in contact. Only when you wear earphones to play music, you will feel the sound quality characteristics of this earphone.
The sound quality of the Mifo Fiitii Hifipods earbuds is the best hybrid driver tws headphones I have ever used. The treble and alto are impeccable, and the most satisfying thing is that the bass is very powerful, explosive, not dull and elastic.
Summary
Adopt hybrid driver design, not simply stacking speakers. According to the lack of high frequency resolution of dynamic speakers and insufficient low frequency of armature speakers, the combination of the two makes up for their respective shortcomings. Using difficult electronic frequency division technology, different frequency division points can be adjusted according to the size of the audio, which can show a higher audio effect.
The application of low-frequency processing technology enables the 8mm dynamic driver to achieve the sound effect of the 16mm dynamic driver through a unique cavity design and a built-in rear cavity guide tube. The bass is very punchy, explosive, not dull and bouncy.
The six-microphone noise reduction can make the maximum noise reduction depth of the earphones 36dB, and the noise reduction bandwidth reaches 2000HZ. Call noise reduction adopts dual-mic+ software algorithm dual-channel noise reduction, even if it is completely placed in the cochlea, it can achieve high-definition calls.
Almost every MIFO product is IPX7 waterproof, and MIFO Fiitii Hifipods are no exception. No matter sports sweat or outdoor rain will cause damage to the earphones.
The adaptive technology that automatically adjusts according to the usage scene can enable low latency when playing games and high-definition audio when listening to music. This is a low-loss digital audio compression algorithm that preserves sound data more completely. Compared with the previous bluetooth codec technology, bluetooth audio can produce sound quality comparable to CD.
Disadvantages: Because the earphone has built-in 3 speaker units, electronic frequency division modules, three noise-cancelling microphones, etc. The battery life of earbuds is 5-7 hours, which is slightly lower than 1-2 hours of other headphones.
