FIIL DIVA is the fourth headset produced by Wang Feng's FIIL. It is a Bluetooth headset, positioned as a music lover, with a neutral style. However, the headset has a full mode noise reduction function, which can still listen to beautiful and pure music in a variety of noisy environments. And as a headset produced by musicians, FIL DIVA is exquisite and comfortable, with certain professional quality.

————————————————　 enclosure 　————————————————

The package of the headset is simple, but it has a small and round storage bag, which is suitable for carrying out on the street. In addition to the charging cable, there is also an audio cable in the accessory. The gold plated plug can reduce the signal loss during audio transmission, because the headset can also be used as a wired headset.

———————— ————————　 work 　————————————————

In order to accommodate more users to take out of the street, in addition to folding the headset, it is also relatively small. Its workmanship is meticulous, the seams are even and small everywhere, the earphones are not big, and 32mm sound generating units are used. Earmuffs are not ear muffs, but smaller ear pressing structures. Its weight is not heavy. In order to reduce the burden on the neck, the earphones are mostly made of plastic, but the process is smooth and delicate, with a ceramic like crystal texture. Metal materials are used in places where there is a lot of force, such as the pull rod. The pull rod is steplessly adjusted, and the damping sense is just right. It does not feel laborious or loose, and it does not move by itself after stretching. The inner side of ear muffs and head beams is covered with soft elastic materials by protein leather, which feels like baby skin. It's wonderful! The middle of the earmuff is soft sponge body, which will not compress the auricle, so it is very comfortable to wear. The FIIL logo on the shell has a bright moonlight white backlight, which can be turned on or off through the exclusive application or power key, which is low-key and luxurious.

The earmuff is connected with the shell in a soft way, which can rotate the earmuff within a certain range to adapt to various head types. Noise reduction MICs can be seen on both housings. In fact, the headset has four highly sensitive noise reduction MICs. Combined with the hybrid noise reduction technology of feedforward and feedback, the headset can still listen to pure music in subway, supermarket and other environments.

————————————————　 operation 　————————————————

The interface and physical switch of the headset are concentrated on the right housing. The keys can be operated in multiple modes, and the operation is relatively centralized. For example, depending on the operation and playing mode, the power key can realize many functions such as turning on/off the machine, playing pause, hanging up the call, power prompt and turning on/off the FIL light. The shell has a touch sensing function. You can adjust the volume and switch songs by swiping your finger across the shell. You don't need to touch keys, which simplifies the operation. However, because the functions are too concentrated, it needs a process of learning and adaptation. There is also a change-over switch beside the power key, which is used to switch between the four modes of noise reduction, simultaneous listening, and open and windy.

————————————————　 ＡＰＰ 　————————————————

FIIL DIVA has a dedicated APP, which can be upgraded online and update the firmware for the headset. The APP details the operation mode of the headset. The interface can directly display the power of the headset, as well as the power on function. This function is to use the pink noise close to the nature to cook the machine. It is highly efficient and can make the headset enter the ideal state in a short time, which is convenient for users.

The EQ of the headset has 4 sound fields and 3 voice colors, which can combine a variety of sound effects. In addition, MAF can also be operated here. The APP also has the function of online music search and voice control, but it seems that it has never been opened. I hope the software will be updated to enable these functions.

————————————————　 Comfort 　————————————————

FIIL DIVA is very comfortable to wear. The protein silk skin is very close to the skin and has excellent touch. The inner lining of earmuff and head beam is soft and elastic, without compression. The weight of the earphone is moderate, and there is no burden in pitching and turning. The damping effect of the pull rod is prominent, and there is no self displacement. The earmuff can be moderately deflected to adapt to the head contour. However, because the clamping force of the ear pressing structure is greater than that of the ear earphone, it is still slightly oppressive to wear it for a long time. In addition, it is unknown whether you will sweat if you wear it for a long time in cold winter.

————————————————　 connectivity 　————————————————

Headset support blue 4 1 With Apt － X protocol, it has lower connection power consumption and longer connection distance. In addition, Apt-X transmission can provide clear audio transmission quality comparable to that of wired earphones, and can enjoy purer audio quality. In the actual experience, the headset supports both the ios system and the Android system. It can connect to the mobile phone quickly and accurately without repeated operations. The signal transmission is stable during the connection. There is no transmission interruption when the distance between the headset and the mobile phone is 5 meters away from the wall. The connection performance is excellent.

————————————————　 Audition 　————————————————

Since the headset is mainly positioned as a Bluetooth playback function, it does not experience the wired transmission effect. This audition is mainly paired with iPhone 6sPlus that supports Apt － X, TuneSell is selected as the player, the audio rate is above 628kbps, and 44kHz lossless audio songs are sampled. The comparison device is Samsung C9pro.

During the audition, I was impressed by its high-frequency performance, which was full and round but not harsh. The intermediate frequency is the cornerstone of the tri frequency. The intermediate frequency of the FIIL DIVA shows the human voice more closely, but it does not have more rendering. It is very straightforward tuning. The low frequency of FIL DIVA is not deliberately depicted. Its low frequency diving depth is not deep, but its density performance is excellent. Although there is no movement, it can create a spatial atmosphere, which is better than the medium frequency performance. It has outstanding performance in separation, rich sense of hierarchy, good performance in musical instruments, good performance in orchestral music, piano and other instruments, and excellent performance in sound density, but its analytical power and sound field width have not reached a very high level. Its style is a saddle shaped one with thick sides and thin middle, suitable for hearing sensitive high and low frequencies, suitable for young people who love to go out of the street, and not suitable for enthusiasts who are interested in Hi Fi. It is trying to be a popular lover, suitable for the hearing habits of more people. It does not over render for a certain frequency band, and its style is straightforward. Overall, its comprehensive performance is not inferior to that of wired headphones at the same price.

————————————————　 noise reduction 　————————————————

FIIL DIVA has four MAF modes. The simultaneous listening mode can listen to music while talking with people. The open mode does not cancel any noise, which is particularly beneficial to personal safety when crossing the road. The noise reduction mode can filter out background noise and enjoy music more quietly. In addition, the headset has a wind mode, because the wind noise is complex and difficult to sample, Usually, it is not clear whether the noise belongs to external noise or internal noise, and it cannot be filtered accurately. FIIL DIVA specially sets this mode for this phenomenon, which can effectively resist wind noise and achieve full mode noise filtering. In my opinion, noise reduction is the most important function of FIL DIVA, because it is targeted at the broad audience. It is more important to get pure sound in various noisy environments than sound quality performance, otherwise even the best sound quality will be destroyed by noise. In fact, FIIL has devoted a lot of effort to the noise reduction effect of this headset. This earphone has four highly sensitive noise reduction MICs, and adopts the active noise reduction technology of feedforward+feedback, which can identify the background noise and accurately simulate the noise source and its cancellation. It has obvious effects in many scenes. The environment in the train compartment is very noisy. When I wear the FIIL DIVA, I can hear the conversation of the passengers in the opposite seat clearly. When I switch from the part-time listening mode to the noise reduction mode, the conversation is almost inaudible. I can only hear their loud cough. The noise reduction effect is obvious and the low frequency is partially enhanced, and the sound quality has no obvious loss, but it is slightly dull, But it is also very comfortable to listen to music in such a noisy environment.

————————————————　 Endurance 　————————————————

The endurance of FIIL DIVA is strong. When the machine is warmed up at 50% of the volume, 10% of the power is consumed in about three hours, which is very close to the official endurance of 33 hours of continuous playback. However, this endurance test was actually conducted in a low temperature environment of - 15 ℃, which will have a certain impact on endurance. It seems that the official data is very cautious. FIIL DIVA also has an intelligent sensing function. Its head beam is equipped with a pressure sensing chip. When the clamping force disappears, the audio will automatically stop playing, which is particularly helpful for the endurance of the headset.

————————————————　 impression 　————————————————

The light and compact appearance, the delicate seams like hair, and the intimate touch like baby skin all reflect the persistence of a musician. In terms of sound quality, it has excellent performance in high and low frequency, sound density, separation, dynamics, etc. Take off the music and stop, put it on and continue to play. You can control it with a stroke of your finger. Everything is like flowing water. Musicians have devoted a lot of efforts to noise reduction effect by listening to music quietly in various noisy occasions for the broad audience. Of course, it also has some imperfections. The hasty APP and online music search, voice control and other functions need to be supplemented. The over centralized control requires a certain learning cost, but these trivial things do not affect its ability as a qualified lover of mass music. Wang Feng's FIIL DIVA is a gift for mass musicians.
