I wonder if you have taken out wired headphones but can’t find the headphone jack for your phone? As mainstream flagship mobile phones have successively cancelled the 3.5mm headphone jack and moved towards integration, we have gradually chosen Bluetooth headphones as our daily headphones.
Major manufacturers are also thinking: Since the headphones are wireless, they simply pull the wires completely, making real wireless headphones more convenient! So with the mentality of "Since my shoes are wet, I'll take a shower", major headphone brands have launched their own fully wireless headphone products.
Yes, I believe everyone has guessed the preface. What we want to evaluate is the upcoming true wireless headset - the FIIL T1 true wireless sports headset. This is also FIIL's first TWS (true wireless) headphones. FIIL is a headphone brand personally participated and founded by the famous rock musician Wang Feng . Friends who are not familiar with this brand, please click on the evaluation link below to learn about it: evaluation link

FIIL T1 true wireless sports headphones
OK, without further ado, how does this headphone perform? Can it refresh us? Let's have a good review and find out!
FIIL T1 is the first to start: simple and round, I want to play it
The FIIL T1 I got is the obsidian black version. OK, if worn by a boy, black will look more low-key and calm.

FIIL T1 true wireless headphones
Let’s first look at the appearance of this headphone: the shape of the headphone cavity is a relatively circumferential oval. The front of the cavity is a polished shiny surface, which feels warm and smooth, and there is a desire to "dispense" it again after it is ready.

FIIL T1's single headset is about 4g, which is very light to wear. Around the earphone cavity, there are special design RotateSecure ear wings developed by FIIL and CNIS ergonomics laboratory. They are locked inside the ears and are comfortable and firm to wear.
talks about the headphones themselves, let’s take a look at its charging case. The FIIL T1 charging box is square, with an overall matte texture, and the charging box with rounded corners around it does not look abrupt. The box charging base has a magnetic suction setting, the headset is automatically absorbed and charged when placed in, and there is an indicator light on the front. The indicator light on the front of the charging box is on, indicating that you are charging
and look at the back after looking at it! There is a charging port on the back of the charging box. When I opened it, I found out...

emmmmm...
This does need to be improved: the USB charging port is outdated now. Although a charging cable is included, the occasional forgetting of the user will lead to the embarrassment of not being universal. I hope that the charging case of the next generation of true wireless headphones will be changed to a type-C interface.
FIIL T1 Wearing: This is easy to wear
We all know that when "technology products" are not as technological, in a sense, their annoyance can be called "artificial intelligence retarded". In fact, the same applies to true wireless headphones: if the signal of true wireless headphones is unstable and the delay of disconnection is severe, it is better than a hearing aid!
So this time we mainly look at the conventional performance of FIIL T1 headphones. Can we satisfy us?

FIIL T1 true wireless headphones
First look at its connection usage: for the first time, the headphones will automatically synchronize left and right to right, and enter the pairing state. What’s very eye-catching is that after completing the first pairing, every time you use the headphones, you just need to open the battery box and the headphones will be automatically paired without other manual operations. It is also very simple when not in use. After the headset is placed in the battery box, the headset will automatically disconnect.

is easy to connect and the headset is also very convenient to operate. Both FIIL T1 supports touch operation. You can complete playback, answer, call Siri, and even adjust the volume by just one finger. There is no need to take out your phone repeatedly when you exercise.This test is very sensitive, and the sweaty hand does not touch it by mistake, which is very good~

In terms of signal stability, the FIIL T1 headphone uses Taiwan Realtek RealtekRTL8763B Bluetooth chip, supports Bluetooth 5.0 technology. It also applies the LDS antenna technology used by iPhone to the headphones, making the headphones more stable sound transmission, lower power consumption, faster connection, lower delay, and stronger compatibility. When testing the headphones in
, it was found that the signal of FIIL T1 is indeed very stable, and even in subway basements and other places with heavy interference, there is no problem. There will be a delay when watching videos with games, but they are all negligible and will not affect use at all.

In terms of battery life, the FIIL T1 headset uses MorpheusSTB intelligent power consumption optimization, with a battery life of up to 6 hours in a lightweight body. The customized battery box can provide additional 3 full battery life for both ears while storing, totaling 24 hours.
After testing, the FIIL T1 headphones can last more than five hours in a single battery life, for nearly six hours, but when users actually use them, they will hardly wear headphones for more than five hours, and they will put the headphones in the charging box when they are not in use. In this way, the headphones and the charging box can provide two to three days of battery power.

Close-up
As sports headphones, waterproof and dustproof are essential "basic". FIIL T1 headphones reach the level of IPx5 waterproof and IP6x dustproof, with a nano-waterproof coating design that protects the internal circuits of the headphones, without fear of rain erosion, and even more fear of sweat erosion.
, FIIL T1 headphones support binaural high-definition calls, built-in special noise reduction microphone, DSP technology eliminates ambient noise, and can also enjoy high-definition calls in noisy gyms.
FIIL T1 sound quality: good sounds and does not go the ordinary way
sound quality is also an indispensable part of our evaluation of headphones. Although the sound quality of true wireless headphones has always been criticized for being "average".
So can this FIIL T1 headphone with a 6mm high-density rubidium magnet dynamic coil unit and professional tuning earplugs bring us some surprises?

headphones listening...
FIIL headphones 's first listening experience is three words: Not ordinary. After listening carefully, I slowly discovered the extraordinary reason: the analysis should be better and the listening experience is simpler. Generally speaking, the strong bass is a common advantage of real wireless headphones. It is very touching but will get tired of it after listening for a long time, because it will almost always be analyzed.
. The FIIL T1 headphones have outstanding resolution, clear layers, full sound field, and excellent details. The mid-frequency of the headphones is soft and delicate, the vocals are magnetic, and the nasal and teeth sounds are clear; the high-frequency transient response is fast, and the rendering of the instrument is great! Although the low frequency is not thick and strong, it is just right, and the overall listening experience is of clean and bright type.
was written at the end
As a new headset brand, the all-wireless headset launched by FIIL this time is considered a "conscience". In fact, true wireless headphones are the product of the fusion of "freedom" and "sound". Although FIIL T1 headphones also have flaws, we clearly realize that true wireless headphones should look like this, allowing people to enjoy convenient and freely!
By the way, the FIIL T1 true wireless sports headphones will be pre-sale on March 1, 2019 and will be fully launched on March 14, with an estimated price of 399 yuan. There will definitely be discounts on pre-sales, so please pay close attention!
