Before starting, talk briefly about headphones. Do you buy them based on their appearance, price, configuration, brand or belief, such as the smile from their uncle (Sony Dafa is better), belief from the lamp factory, Baya or Senhai? For users who dare not burn or cannot afford to burn, price positioning is a prerequisite (reasonable budget), then compare and select hardware configurations and functions, and finally see the appearance. Of course, it is necessary to go to some physical stores or stores for audition.

The emergence of smart headphones is an inevitable trend, but it is only a matter of time. The VINCI smart headwear is not the first smart headset. As a user of traditional headphones, he is not really impressed with its main social function. The first impression is that VINCI is positioned as a smart and intelligent product for the sake of intelligence. It is a cool new trend for young people to brush the street. Because there is undeniable innovation in design, it is extremely easy to be noticed and become the focus when wearing it.  

However, as an intelligent hardware player, he is not exclusive of intelligent headwear, because there are many things worth experiencing. Compared with traditional earphones, VINCI is more like a combination of player and earphone.

For this VINCI 1.5Lite, the hardware attraction is the design of 40mm sound unit with beryllium diaphragm. This diaphragm is different from the one I have used, and the effect is worth looking forward to. The highlight design not only has its own touch screen and supports voice recognition, but also supports active noise reduction, heart rate measurement and motion monitoring and positioning. These are very practical functions.

The design supporting SIM card is a plus. The intelligent headphone can be used for multiple purposes, and can be used independently, or as a Bluetooth headset with other Bluetooth devices, or as a wired headset. However, for the audio quality, the headset products can only be reviewed if you listen to and compare them yourself.

Products

Habitual summary, first have a general impression. This headphone is not a so-called concept machine, but a real product. Your impression of VINCI may change from player+headset to 3G Pad+headset.

Know VINCI 1.5 Lite, simple and beautiful, but difficult to disassemble

The first impression is the bright Chinese red, very festive, but the headset can not be folded. The material and workmanship are exquisite. The earmuffs are of ear wrap design, and the earmuffs are not easy to remove. The material used for the head beam is somewhat similar to the alloy material, which looks more textured with the spraying process.  

The head beam adopts a pull out adjustment mode, which can be adjusted within a certain length, so as to listen to the head shapes of different sizes. It is a pity that the head beam is not foldable. The joints are made of aluminum alloy, so the resistance is large when adjusting, and there is an obvious sense of frustration.  

The head cushion inside the head beam is made of rubber, and the surface is smooth and easy to clean. The interior is filled with memory cotton, which is soft and comfortable, and will not have too much pressure on the head after wearing.

The ear pad is made of extremely soft leather and filled with memory cotton. It is soft and comfortable to touch and has excellent air permeability, which greatly reduces the pressure on the ears after wearing. The earmuff is not fixed, but can rotate up and down within a certain range to better fit the ear. The ear pad has excellent air permeability. When the temperature is 20 ℃, there will be no sweat due to wearing it for a long time (room temperature is 18 ℃, about 3 hours).  

VINCI 1.5Lite supports the function of heart rate measurement, as well as the function of listening, taking off and stopping when wearing. The sensor part is on the right ear side, and the bare part below is the heart rate monitoring module.  

From the green indicator light, the heart rate measurement principle adopted by VINCE 1.5Lite is actually the same as that of the smart bracelet or watch. In short, it is to use green LED light, together with the corresponding photosensitive device, and use the principle of blood reflecting red light and absorbing green light to measure.

The square design is somewhat different from the traditional round design. To some extent, it is related to the internal hardware, such as the 40mm sound unit and various sensor chips, so it looks larger than the traditional earphone.  

VINCI one point five Lite's design features not only the square ear muff shell, but also a built-in 3.2 inch touch screen with a resolution of 480 * 360, which can be used to set some parameters and display text and patterns. The circle below is the Home key, which is used to return to the main interface. From the design and hardware parameters, this side is actually more like a tablet computer.

As a headset supporting voice interaction function, noise reduction mic is very necessary. The small round holes at the symmetrical parts on both sides above the figure below are noise reduction mic. Below the noise reduction mic on the left are the power switch key and the SIM card slot. The key is slightly soft and needs to be pressed hard. The thread process on the surface has a slip resistant effect. The slot is made of plastic and soft. The supported SIM card type is NANO.

The SIM card only supports Unicom 3G. Even if your Unicom card is a 4G card, the mobile SIM card can only use 2G. VINCI one point five Lite itself does not support external memory cards. If the SIM card and TF card are designed as two in one, they will be more practical. Although there is a complimentary SIM card and three months of free traffic, one problem is how to calculate the time. For example, the service of this SIM card has been suspended. This is something the manufacturer needs to consider, because it is related to the actual use of users.  

What is mentioned above is only the noise reduction MIC. The main mic is located at the lower right side, which is closer to the mouth when worn. In addition to the main MIC, there are interfaces for matching 3.5mm audio cable and Micro USB charging interface. The biggest advantage of the detachable headphone cable design is that you can freely choose the headphone cable for use. However, the design of the audio interface is too large for the exposed space around, which is ugly and easier to get dust. It would be better if both interfaces were equipped with dust plugs, and it would look simpler.

Since the headphone jack is a standard 3.5mm jack, it can be used together with Samsung Level ON (remote control) and JVC headphone cable, but can the remote control function be realized? Yes, it can be used with Samsung Level on headphone cable to control Samsung Android phones, such as volume adjustment, making calls and calling S-Voice.  

Similarly, the VINCI 1.5 Lite headphone cable can also be used on Samsung Level On and JVC. Double head 3.5mm plug adopts gold plating process to prevent oxidation and reduce interference in signal transmission.

Now let's enter the actual experience stage and comment on the function and sound quality.

Self contained system, slow and sensitive touch screen, fun and practical gesture operation

As an intelligent head machine, it has many functions, so this part is video introduction, and you can directly watch the corresponding video content.

It takes about 42 seconds from power on to entering the system, which is slow and needs further optimization. The boot interface used for the first time is more detailed, and you can quickly complete the settings according to the prompts.

//v.qq.com/x/page/r0387fmv6hi.html?ptag=qqbrowser  

VINCI 1.5 Lite has three usage modes, namely independent headset mode, Bluetooth headset mode and traditional headset mode using audio cable. The question is, can I use it directly with the audio cable if I don't turn it on? Yes, but the sound quality is not as good as that after power on. As for the reason, it should be related to the integrated DAC chip.

As a Bluetooth headset, its compatibility with different devices is a concern, because it is usually connected to mobile phones, tablets, TV boxes, smart TVs and other devices. From the actual situation of connected devices, the compatibility is relatively stable.  

Pay attention to the front high-energy, which is a small surprise in actual operation, that is, the control function of video playback is realized through the touch screen. At present, the video can be paused and played with the screen bully, but fast forward and fast backward and volume adjustment cannot be used for the time being. In theory, such operations should also be achieved. It is expected that the common play functions can be controlled by the touch screen in the future. However, I hope that the voice interaction of VINCI can be supported to control the screen bully, Because Pingba also supports voice interaction.

In Bluetooth headset mode, some songs played by mobile phone APP or its own player can display the song name and artist on the screen, but songs played by PC can only display unknown. In Bluetooth mode, you cannot only display the Bluetooth settings page and cannot access other settings pages. All operations are performed on the connected device end, that is, the functions of the smart head machine cannot be used. If you want to continue to use the functions of the VINCI smart headphone while connecting other devices, you just need to check "Accept message notifications only".

The system adopts its own Android based ME OS (V2.0.1)， The fluency and stability need to be further improved. Occasionally, the program will report errors. VINCI 1.5 Lite can be directly connected to PC , copy songs in MTP mode, copy audio files directly into the Music folder, and the copy speed is relatively stable. VINCI 1.5 Lite supports mp3, AAC, AMR, ALAC, FLAC, WAV and AIFF, not many of which, but several high-definition music formats. The available space seen on the PC side is only about 4G, which is quite different from the 9G seen on the headset side. It is inferred that a part is reserved for the headset side to cache or download songs.  

There are many functions, so I recorded a video for demonstration.

//v.qq.com/x/page/o03872wjqj6.html?ptag=qqbrowser

The 3.2 inch touch screen has excellent animation and font display effect. Eight kinds of music visual display similar to screen saver are more fun, but they do not support the function of custom patterns, nor can they be downloaded from the network. This is something that needs to be improved. After all, it is part of personalization. The screen can display the song name but does not support the lyric display function. But think about it. When listening to a song, the lyric is displayed. I see some stupid, but you can't see it anyway. The touch screen is more sensitive, and gesture operation can be accurately recognized. Gesture control is a special function other than voice control. It can complete different functions through simple sliding, clicking and double clicking. It is suitable for blind operation. It is not necessary to take off the headset like an idiot to operate and then put it on.

The picture above is the main picture of the headset, and the three circular patterns below represent recommendations, local music and listening together.

For the recommended songs for you, most of the more than 620 songs you listen to are English songs, but most of the recommended songs are Chinese songs, occasionally Korean songs and English songs. The accuracy of data based recommendation needs to be improved, and the learning ability needs to be improved.  

In addition to displaying downloaded and copied songs, local songs also collect favorite songs and recently played songs. For songs in favorites and recent playlists, even if there is no network, they can be played directly for audition. Because VINCI 1.5 Lite uses the method of listening while caching, this design is more practical and convenient to use when there is no network.

In fact, listening together is the official music social function. Add friends and listen together. After adding friends, you can check the status of your friends' favorite songs in the V circle. Listening together is to share songs with each other for audition. You can add them face to face or push them, so that two earphones can play the same song at the same time. The function is worth experiencing. It is suitable for lovers and girlfriends to share, but the premise is that the other party should also have a VINCI headset. If you join in the APP, it will be more practical.

Voice interaction experience with high recognition rate

Excellent voice interaction experience is directly related to the actual speech recognition effect, VINCI one point five Lite can not only recognize voice commands normally in standby mode, but also recognize voice commands when playing songs, which is a good place to do. There are two ways to access voice recognition: one is to command "small mi small mi", the other is to press the touch screen for a long time and then say voice commands after hearing "dong". The following is the video connection of the experience.

//v.qq.com/x/page/y0387pft2pg.html?ptag=qqbrowser

The recognition rate of VINCI 1.5 Lite in the online mode is very high. In the official introduction, it is said that the tripartite technologies adopted by Yunzhisheng, iFLYTEK and Baidu are more surprising because their poor English can also be recognized, especially such long names as Linkin Park and Justin Timberlake.  

For music playback, you can simply say "Play", "Pause", "Previous Next", etc. to complete common function operations. For other commands, such as querying the weather, searching for songs, etc., just shout "Small Mi small mi”， After hearing a ding dong sound, you can then say the command. The content does not need a specific format. It can be used freely but not too long, but it must be able to be spoken within a preset time and recognized by VINCI. The voice is somewhat mechanized, worse than Siri, and much worse than the English voice of VINCI abroad.  

Is offline voice mode supported? No, it must be connected to the Internet, so that the recognition rate is higher and the user's interactive experience is guaranteed. In a sense, it is also the reason why the SIM card is designed to keep the connection mode.

Audio quality comments not only listen to music, but also watch movies together

Before the formal audition, there was a cooker, which lasted a long time. First, because the initial listening effect was ordinary, and second, in order to ensure an objective audition effect, there would be detailed changes in the vocal and bass effects before and after the cooker. The comments are limited to personal limited cognition, and are explained in straightforward language. The following experience content is compared with the AKG in use K66, JVC HA-SR100X and Samsung Level ON.  

First, let's talk about the 3D sound effect or three-dimensional sound effect. There are some effects, which make the sound field wider and can bring more immersive effects.

The vocal part of the performance is stable, whether it is singing, pop or rock songs. The voice is clear, crisp and mellow, with good analytical power, and excellent performance in details. Breathing sound and lip and tooth sounds can be clearly felt. There is a certain degree of separation and hierarchy between the voice and the instrument. The voice is more forward, which can restore the high and low parts of the song. With Joshua Radin's "I'd rather be with you" is a song with a light and sentimental rhythm, soft and free, VINCI 1.5 Lite can more accurately restore different musical instruments, better depict the feelings of the characters, and a slightly hoarse voice can have a penetrating power, giving a real feeling of singing in the ear. There is still a feeling of unfinished at the end of a song. Ed Sheeran's Shape of You, as Billboard's airborne champion song, has a lively and dynamic rhythm, but here we choose the Accousic version for audition Sheeran's singing skills were closely auditioned, without some background music, and only matched with a guitar, making Ed Sheeran's voice is more authentic. The first part of the humming is easy and natural, giving a feeling of humming in the ear. With the development of the rhythm, whether it is non broken or sharp treble or part close to rap, the articulation is clear without confusion. For powerful singers like Cai Ma and Zhao Peng, their voices can be well displayed. Take "Moonlight Serenade" as an example. Cai Ma's voice can be played in and out freely, without explosion or harsh sound. Her voice can be extended very well, giving people a comfortable feeling of singing in the ear. Not only can you breathe, but also can you hear crickets and frogs in the background.

High frequency performance is regular, with a certain analytical power and ductility but not high, poor sense of strength, not bright enough timbre, but without a sense of sharpness or burr. Use the test disc MUTTER VIOLIN Solo 1》 For example, the change between high and low pitch, fast and slow is natural and smooth without procrastination, the whole song has no sharp sense, and the slight lack of extensibility has led to the decline of the shock of the song. 《Beethoven Virus presents a magnificent picture through the integration of different musical instruments. It gives people a feeling of tension and excitement. There is no sense of confusion. It has a good performance on the level of separation, but a poor performance on the strength.

In terms of bass performance, I feel a little heavy, with enough volume, a certain depth of diving, and more relaxed and free without tailing. For the "Sad City" and "2001 Space Odyssey", the low sound of musical instruments at the beginning can be well restored. The switching is natural and smooth without a sense of procrastination. The transient performance is excellent, and the percussion sound of musical instruments can be more accurately restored. In Drum Poetry, the sense of percussion is strong and powerful, but in the second half of the dense drum sound, the bass effect is more obvious, resulting in a dull drum sound.

It is suitable for watching movies because VINCI 1.5 Lite can bring a sense of encirclement, immersion, layering and space. It is suitable for watching some movies with dts HD, Doby Audio and other sound effects. The experience will be more intuitive.

For some films with excellent sound effects, such as Silent Ridge 1, Gravity, Speed and Passion and so on, they can better contrast the plot atmosphere and bring visual and auditory feelings. In Speed and Passion, it is mainly the scenes of street drag racing and fighting that bring auditory shock. The roaring Ma Dasheng and beautiful women make the film have both speed and passion. The music part is particularly important, VINCI 1.5 Lite can better restore the soundtrack and the roar of the vehicle, and can show the motor sound of the vehicle from far to near, from near to far.  

One hour charging, four hours of independent play

VINCI one point five Lite has a built-in 1500mAh lithium battery, and the power adapter is 5V-1A, which can be used in common with the power adapter of some Android phones. It only takes about one hour and 33 minutes to fully charge after powering off at low power, and it can be charged to about 85% in one hour. After 3D sound effect, Bluetooth, 3G, voice wake-up and tape picking induction are turned off, local songs can be played continuously for about four hours (related to songs and volume), which can meet the needs of outdoor travel.

The necessary APP synchronization management tool for smart headphones is Android APP

Generally speaking, intelligent devices have more or less an APP, and VINCI also has a corresponding mobile APP, which is used to synchronize some playing records, collect records, download recording files to the mobile phone and check the heart rate. Its functions are still improving. After the phone is connected to the headset via Bluetooth, you can play the recently played or favorite songs in the APP. If the headset is not connected, these songs will be played on the mobile phone. In the play interface, you will see a download icon, which is the function of offline download. Offline download is actually to download some songs with play records or collections to the headset by operating on the APP. The download is saved to the storage space of the smart headset rather than the handheld terminal. Heart rate measurement is a real-time measurement, but at present there is no function to continuously record the heart rate, nor can it be displayed in graphical form. The last measured data is automatically saved before removing the intelligent headwear. Is the heart rate measurement accurate?  

This time, we compared the real-time heart rate measurement values of Xiaohei 3. Xiaohei 3 has little measurement error with traditional wrist and arm blood pressure meters, which is of reference value. As can be seen from the figure below, the heart rate measurement value of VINCI 1.5 Lite does not have much error with that of Xiaohei 3.  

At present, there is no option to upgrade OTA in the APP, nor the function to burn earphones. At present, the three major categories are my earphones (the management page after the earphones are bound), V-circle (similar to the circle of friends, displaying favorite songs), and forums (sharing and feedback problems). There are not many parts worth in-depth experience. I hope to add the function of searching songs in the APP. I can customize some music related APPs, such as Netease Cloud Music, Baidu Music, etc., and automatically synchronize and save them to the headset.  

Figure 1 shows the picture of a successful call after Bluetooth is connected to the mobile phone. The 11 digit mobile phone number can be identified and called normally. The default is the VINCI smart headset; Figure 2 shows that the 3D recording files in the VINCI smart headwear will be automatically synchronized to the cloud, which can be seen on the APP and downloaded locally. This 3D recording makes good use of the two noise reduction mics on the left and right ears together with the main mic to collect the sound from the surrounding environment. It can use algorithm simulation to reproduce the current environment to achieve 3D effects; Figure 3 shows IOS The content displayed in the APP sports fitness measurement data is somewhat simple, and the steps can be recorded, but the steps and distance will not be displayed, but the steps and distance information can be viewed in the Android APP. The two versions of APP do not have a built-in map, so they cannot view information such as tracks. It is expected that the functions will be improved after subsequent upgrades.

Creative and insufficient playthings suitable for smart hardware players and trendsetters

For the emergence of smart headsets, in a sense, it is also a practical product transformed from the needs of a part of the population. In short, it is an intelligent hardware that integrates players and earphones and increases its functions. It is a creative product.  

For VINCI one point five Lite， Functionally, it can meet the use needs of listening to music and chasing dramas at ordinary times, and the sound quality is not too disappointing. The three use modes of independent player, Bluetooth headset, and wired headset meet the use of different devices in different daily scenes. The gesture control and voice interaction function with high recognition rate have greatly improved the user experience and are more consistent with the characteristics of intelligent hardware. The hardware configuration and functions are suitable for intelligent players. At the same time, the unique touch screen with cool graphic display and the alternative design of square earmuffs are more suitable for the attention of trendsetters.  

But at the same time, we should also pay attention to, VINCI one point five Lite still needs to be optimized and improved in detail design, system performance and functions. It can only use 3G network with Unicom SIM card, which makes the device more limited in networking. If the card slot is designed as a combination of TF card and SIM card, the space expansion will be higher and more practical. In other words, since the card can be inserted with a mic, if VINCI can be used directly 1.5 What kind of experience would it be like for Lite to make a call?
