FIIL IICON
Q1
How to connect my FIIL IICON via Bluetooth?
Bluetooth search: In power-off mode, press and hold the multifunction button for about 5 seconds until the logo LED is flickering. You will first hear the startup music, then the voice prompt indicating the battery. Do not release until you hear the voice prompt "pairing". Then you can see your FIIL IICON on the list of Bluetooth devices. Just click to connect.
Note: "Open Detection" needs to be enabled on some Android phones.
Q2
How to connect my FIIL IICON to the second device?
By default FIIL IICON will be connected only to the device previously connected (Device A for example). So if you want to connect your FIIL IICON to the second device (Device B for example), you will have to turn it off, press and hold the Power key to do the pairing and connect it to Device B. After that, you will have to connect your FIIL IICON to Device A manually via Bluetooth. By now your FIIL IICON will tell you that both devices are connected.
Note: As restricted by the operating system, you might have to clear up the pairing history of your mobile phone first to avoid connecting problems.
Q3
What does monitoring mode mean in FIIL IICON?
The monitoring mode developed by FIIL is the first in the industry. The principle is to pick up sounds from outside (voice, ambient sound, etc.) through built-in microphones while wearing the earphones and play them in real time. The purpose is to enable you to talk with others or hear the ambient sounds for the sake of travel safety without taking off the earphones.
Q4
Why is the volume so different when using FIIL IICON in wired and Bluetooth mode?
For Bluetooth earphones, we suggest using them in Bluetooth mode. It is normal that the volume varies among different modes. The default values of volume are different in factory settings. The maximum value of the earphone volume in Bluetooth mode is decided by the value of the phone volume at that time. When the earphones are switched from Bluetooth mode to wired mode, the value of volume will be reset to default (which is lower) for hearing protection. You can slide the earmuff (that is, touch pad) to adjust if you want.
Q5
Why is it that the Bluetooth transmission range of FIIL IICON is less than 330ft in actual usage?
The 330ft Bluetooth transmission range refers to the maximum connection distance in an open space without any obstruction and shelter. In actual usage, the Bluetooth transmission range might be affected by obstruction, shields and electromagnetic surroundings, or even affected by Bluetooth performance of different devices like mobile phones.
Q6
What does NFC function mean in FIIL IICON?
If your mobile phone is NFC supported, you can use the NFC function on your mobile phone to directly connect to your Bluetooth earphones powered on, without any manual pairing.
Q7
Why there are some subtle noises in FIIL IICON under Bluetooth connection?
Bluetooth transmits electronic data and is restricted by some chip platforms, which may result in slight current noises. The engineer will optimize the configuration of audio system parameters later by upgrading the firmware.
Q8
Why is it that I cannot connect my FIIL IICON to the computer via Bluetooth?
FIIL IICON is mainly designed to be used with mobile phones and portable devices. As different types of Bluetooth chips might be used in different computers, it is impossible to carry out a compatibility test for all computer systems. So full compatibility cannot be guaranteed. But generally speaking, you can always connect your FIIL IICON to your device if Bluetooth is available, regardless of Bluetooth version.
Q9
Why is the noise canceling function of FIIL IICON not so effective?
1. The noise canceling function of FIIL IICON is effective in a noisy environment instead of a quiet environment (e.g. a quiet study room). 2. Balance between noise canceling and music replaying is required. Excessive noise canceling might compromise the sound quality, which is an inherent limitation of the ANC technology. 3. The ANC cannot reduce noises within the frequency bands of human voices excessively, but mainly reduces high- and low-frequency noises (e.g. ambient sound, tire noise, engine noise). One reason is because of the inherent feature of the ANC technology, the other is for the sake of the wearer's travel safety.
Q10
Why can I still hear the sound from outside even when the noise canceling function is enabled on FIIL IICON?
The ANC cannot reduce noises within the frequency bands of human voices excessively, but mainly reduces high- and low-frequency noises (e.g. ambient sound, tire noise, engine noise). One reason is because of the inherent feature of the ANC technology, the other is for the sake of the wearer's travel safety.
Q11
It is not so responsive to slide to skip song or adjust volume on FIIL IICON.
1. When sliding the FIIL earmuff to skip song or adjust volume, you have to slide your finger from one edge of the earmuff to the other. You will enjoy a significantly higher success rate when you are familiar with the operation. 2. A few number of mobile phones and players may not be supported, but it is recommended to do a cross test by replacing the mobile phone or player so as to identify the reason.
Q12
How to judge the battery status of my FIIL IICON by indicator during charging?
Red light flickering = battery < 10%; Yellow light flickering = battery 10%-80%; Green light flickering = battery > 80%. The indicator will be off if fully charged.
Q13
Can I take the battery out of my FIIL IICON? How long the battery can be used?
No, the battery cannot be removed. Make sure that the battery is not dead if you are not using the earphones for long and charge your earphones at least every six months. The battery capacity remains higher than 80% even after 500 charging/discharging cycles.
Q14
Do I have to burn in my FIIL IICON?
No, you can still use the earphones if you don't want to burn them in, which is also compliant with the sound quality requirements of FIIL. But it is not recommended to use them at high volume. Anyhow, burn-in is a process to put the earphones into the best state faster. Vibrating diaphragm might be tight on new earphones, and burn-in can make it stretch quickly to deliver a more pleasing sound. You can decide on your own whether to burn in the earphones. Burn in your FIIL Wired in FIIL+ app is pretty easy.
Q15
Is the earmuff of my FIIL IICON made from leather? Is it difficult to clean it? Can I clean it with water?
The earmuff is not made from leather and cannot be removed and cleaned with water. It is recommended to scrub the surface first with wet cloth (without water dripping) and then dry cloth after using (especially in sweating and oily scenarios) to keep them clean and dry.
Q15
Will I feel uncomfortable wearing FIIL IICON?
The clamping force of FIIL IICON is 5N through investigation and survey. The head band can be adjusted manually. Please stretch it up and down for best wearing comfort. In addition, you can also extend your earphones laterally to a certain angle for a while to relieve the chucking pain. But make sure that the spacing between inner centers of two earmuffs cannot exceed 24 cm.

Q14
Can I connect my CANVIIS/CANVIIS PRO to the computer?
Normally you can connect your CANVIIS/CANVIIS PRO to any Bluetooth device. But do keep in mind that the earphones are mainly designed to be used with mobile phones and portable devices. As different types of Bluetooth chips might be used in different computers, it is impossible to carry out a compatibility test for all computer systems. So 100% compatibility cannot be guaranteed.
Q15
How to check battery on CANVIIS/CANVIIS PRO earphones?
Double click the MFB key. If the green light is on, the battery is higher than 80%. If the yellow light is on, the battery is between 20% and 79%. If the red light is on and flickering, the battery is lower than 10%. You can also judge the battery by voice prompt.
Q16
Why is my CANVIIS/CANVIIS PRO so power consuming?
The FIIL Logo LED is power consuming if on. Listening to music or standby in MAF mode is also power consuming.
Q17
How does the battery indicator flicker when my CANVIIS/CANVIIS PRO is charging?
Please use a charger from official manufacturers to charge your earphones. The required output voltage is 5V and the current shall be at least 500 mA. It is not recommended to use chargers capable of fast charging (5V, 9V, or 12V USB output).
During charging, if the red light is flickering, the battery is lower than 10%. If the yellow light is on, the battery is 10%-80%. If the green light is on, the battery is higher than 80%. The indicator flickers three times every eight seconds. Flickering yellow and green lights indicate that the earphones are charging, with battery state changing from medium to high.
Q18
Can I take the battery out of my FIIL CANVIIS/CANVIIS PRO? How long the battery can be used?
No, the battery cannot be removed. Make sure that the battery is not dead if you are not using the earphones for long and charge your earphones at least every six months. The battery capacity remains higher than 80% even after 500 charging/discharging cycles.
Q19
Why is the actual Bluetooth transmission range of my CANVIIS/CANVIIS PRO inconsistent with the range publicized?
The effective range of mobile phone connection of all Bluetooth earphones refers to the longest distance without obstruction between the mobile phone and the earphones. The effective range of mobile phone connection of all Bluetooth earphones refers to the longest distance without obstruction between the mobile phone and the earphones. In actual usage, the Bluetooth transmission range might be affected by obstruction, shields and electromagnetic surroundings, or even affected by Bluetooth performance of different devices like mobile phones.
Q20
How to burn in my CANVIIS/CANVIIS PRO?
Download the FIIL+ app from Play Store or App Store, install and connect to the earphones. You can burn in your earphones by one click as instructed.
Q21
Why is the smart Pause-Resume function of my CANVIIS/CANVIIS PRO not working?
1. First, check whether the "Smart Sensor" in the app is enabled. 2. Press and hold the Power key and plug in the charger to reset the Start-Stop function. 3. Do a cross test by connecting your earphones to other play platforms on other mobile phones to eliminate the compatibility problem.
Q22
Why is it that it is easy to get stuck when using my CANVIIS/CANVIIS PRO to listen to music or watch videos in Bluetooth mode?
1. It might be because that the surrounding RF environment is complicated. For example, there is a WiFi router nearby or RF interference (e.g. 4G signal of a mobile phone). 2. It might have something to do with the Bluetooth connection settings of the mobile phone Bluetooth chip. 3. It is recommended to do a cross test by changing a location or replacing a mobile phone.
Q23
Why is it that my mobile phone gets stuck in texting when using my CANVIIS/CANVIIS PRO to listen to music in Bluetooth mode?
Texting in Whatsapp on an iOS device is accompanied by texting tones as set in the system. Every texting tone will result in frequent connection and release of the Bluetooth audio channel, which is a common problem caused by system settings instead of a malfunction.
Q24
Why is it shown as successfully connected on my mobile phone but "click to connect" in FIIL+ app?
It is because of the running speed of the app. Therefore, you have to completely shut down the FIIL+ progress in the system or exit FIIL+ and restart it; or you have to reopen the Bluetooth on your mobile phone to identify earphone connection.
Q25
Why can I still hear the voice of people in a quiet environment even if I turn on the noise canceling function on my CANVIIS/CANVIIS PRO but hear nothing if using earbuds?
Earbuds segregate sounds physically while active noise canceling offsets noises from outside. If you are in a quiet environment, the noise canceling effect won't be obvious. But if you are in a noisy environment (like in an airplane or on the road), the earbuds cannot segregate sounds completely as there are too many noises. But active noise canceling can offset noises significantly. Every technology corresponds to a different scenario of application. The ANC technology is mainly used to filter ambient noises like low-frequency noises, whistlers and engine roars. High-frequency noises are mainly segregated physically. Human voices cannot be filtered thoroughly by ANC which is a technical limitation. No brand can ever segregate human voices thoroughly. This is also for the sake of the wearer's safety.
Q26
Why there are current noises when my CANVIIS/CANVIIS PRO is just powered on regardless of noise canceling function and music listening?
If your Bluetooth earphones had been paired with a mobile phone, your earphones will search for the mobile phone previously paired when powered on, which might generate relatively high RF power and large noises of searching. This is inevitable as it is one of the chip's characteristics.If you have previously paired your earphones with two devices, there will be two pairing trials for each device, which will generate four search noises (including the first one being covered by the power-on music and the status casting). After the Bluetooth pairing or four searches are completed, there won't be any noise like this.
Q27
Why are there some current noises when using the mobile phone or the FIIL+ under Bluetooth or wired connection with CANVIIS/CANVIIS PRO?
1. Some mobile phones are not doing well in controlling transmission noises during BLE communication, which has something to do with the Bluetooth chips and RF design of the mobile phones. 2. If your Bluetooth earphones had been paired with a mobile phone, your earphones will search for the mobile phone previously paired when powered on, which might generate relatively high RF power and large noises of searching. This is inevitable as it is one of the chip's characteristics. If you have previously paired your earphones with two devices, there will be two pairing trials for each device, which will generate four search noises (including the first one being covered by the power-on music and the status casting). After the Bluetooth pairing or four searches are completed, there won't be any noise like this.
Q28
Why are there noises using CANVIIS PRO to skip or play a song at a low volume in local mode?
When you are in an extreme quiet environment (e.g. in an anechoic room or late in the evening), playing a FLAC song (relaxing and in other formats that are slightly small), or adjusting the earphones to the lowest or lower volume, you will hear an extremely subtle continuous sound of disk reading during music playing in local mode. The sound might be covered if you slightly turn up the volume, which is related to the optimization of audio decoding and will be further optimized and improved in the subsequent OTA.
Q29
Why are there noises generated in case of bumps when listening to music in my car with the noise canceling function of CANVIIS/CANVIIS PRO enabled? And sometimes the music would even be paused?
When you are driving on uneven surface or deceleration strips, or passing through bumpy road sections, or when you are running wearing your earphones, physical vibration will pose a relatively huge signal impact on denoise circuits, which makes the active noise canceling earphones believe that huge external noises are offset by the corresponding sound wave and hence results in noises. This is inevitable for active noise canceling earphones. In case of relatively huge bumps, the earphones might fall off from the head, making the smart pause/play function believe that the wearer has taken off the earphones. So the music playing will be paused until the bumps are gone.
Q30
What materials are used for CANVIIS/CANVIIS PRO?
The arm is made from stainless steel, the head is made from TR90 memory plastics, and the earmuff and the head interior are made from protein filament leather.
Q31
Is the earmuff of my CANVIIS/CANVIIS PRO made from leather? Is it difficult to clean it? Can I clean it with water?
The earmuff is not made from leather and cannot be removed and cleaned with water. It is recommended to scrub the surface first with wet cloth (without water dripping) and then dry cloth after using (especially in sweating and oily scenarios) to keep them clean and dry.
Q32
What are the differences between CANVIIS PRO and FIIL IICON?
FIIL IICON is a pair of over-ear headphones and has higher airtightness when coupling with ears, more space for sound field and a better passive noise cancelling effect and sound power than FIIL CANVIIS PRO. With FIIL IICON, you can enjoy an immersive listening experience. FIIL CANVIIS PRO is a pair of on-ear headphones, and is small and portable. Its smart functions such as local storage and noise canceling add more highlights and funs for you to wear it on streets.
FIIL+ APP
Q1
How to register / verify my product?
After connecting to FIIL+ app, it will remind you to verify your device by inputting the serial number as found in the following places:
1.On the headband.
2.On the bottom side of the outer box.
Q2
What is the common solution if the mobile phone connection via Bluetooth is normal but the app connection fails?
You can try following steps:
1. Shut off the FIIL+ app. 2. Ignore the Bluetooth devices the mobile phone previously connected. 3. Restart the mobile phone and the earphones before reconnecting. 4. Charge the earphones for one minute. 5. Uninstall and reinstall the app.
Q3
How long does the "one-click burn-in" in FIIL+ app take?
The burn-in process in FIIL+ can be divided into four phases. The burn-in volume in each phase is respectively at 25%, 50%, 65% and 80%. Therefore, please make sure that the mobile phone volume is kept at over 80% and the app will adjust the volume automatically in different phases. Every burn-in phase can be divided into five nodes, each of which might take 150 minutes. So the burn-in will take 50 hours in total.
Q4
Do I need to pick up music for burn-in?
No, you don't need to pick up and play music as pink noise has already been set in FIIL+.
Q5
Are there any items to be noted in burn-in?
The burn-in process will not affect the use of your mobile phone, but if you need to open other apps that might use the earphones, the burn-in process will be interrupted automatically. You will have to manually resume the burn-in process if you want. The duration of every burn-in shall not be too long, three hours recommended. During burn-in, you will have to disable the ANC active noise canceling and try to avoid listening to music in large volume before the burn-in is fully completed. It is recommended not to use the earphones for more than eight hours a day.
Q6
If I have already done 3000 minutes of burn-in, can I continue?
It is up to you.
Q7
What is the purpose of burn-in?
The burn-in is mainly a process of accelerating the aging of the earphone mechanical system. The vocal system of dynamic earphones generates sounds as the voice coil drives the vibrating diaphragm fixed at the earphone hanger. Theoretically speaking, the movement of the vibrating diaphragm is a piston (vertical) movement which requires relatively huge compliance of the edge. That is why we have to do the burn-in. The edge of the vibrating diaphragm of a new pair of earphones is relatively tight and highly elastic but less compliant, therefore, we have to burn in the earphones to stretch the edge and loosen it.
Other FAQs
Q1
Some functions of the earphones cannot be used on some Android phones, why?
There are many Android devices on the market and we cannot guarantee 100% compatibility of the earphones, but only compatibility to a majority of mainstream mobile phones. In addition, many manufacturers of Android mobile phones did not follow the official requirements of Android, which also leads to the existence of compatibility problems.
Q2
Why is there ground noises, current noises and rustling?
For electronic products, the SNR(Signal to Noise Ratio) is inevitable. It is just that the perception and endurance of noises may vary with people. Currently the quality of FIIL earphones is at normal level internationally. (Bluetooth transmits electronic data and slight current noises are normal. It is just that everyone may have different sensibility towards the sound and the volume).
Q3
When using the earphones, the music playing stops or changes to the speaker mode after three beeps are heard.
This is because that the A2DP of the mobile phone is switched to the SCO channel. As this is controlled by the mobile phone, it is suggested restoring the mobile phone settings or using other apps and changing the settings.
The SCO refers to the Bluetooth voice channel and is used for voice communication. Therefore, the sound quality refers to the voice quality. That is why there are three beeps (low, low and high) when connecting via the SCO. The A2DP refers to the Bluetooth music channel and is used to play music. Our earphones are slave devices serving the master devices (mobile phones). Therefore, the channel we are using is subject to the link initiated by mobile phone (either it is SCO or A2DP). We cannot select on our own but accept. After three beeps are heard, you will know that the system initiates the SCO connection and the earphones will respond accordingly. This has nothing to do with the earphones as it is impossible for the earphones not to respond to the connection initiated by the mobile phone system.
