At the beginning of the year, he bought a BOSE QC20 for his noise reduction function. In fact, he had already had a long-term saliva. He also borrowed a friend's trial for a while before he bought it. It really poisoned, and he would not do too much for QC20 here. Introduced, the only bad news is that the QC20 is not wireless, and the wireless QC35 is head-worn, it is inconvenient to go out to use, if the QC20 has a wireless in-ear style (do not talk to me QC30 ... I can not accept it ).
Well, we're back to the point, and the K420 that has been in the home for many years is almost the same (excuses). It's time to replace it. The budget is around RMB 1,000. Although it is mainly used at home, I still need to have a noise reduction function. Wireless, these requirements are demarcated. In fact, there are not many choices. The first reaction is thought of by Sony's 1RNCMK2. The 100ABN is too expensive to consider. The other is the FIIL DIVA Wang Haibi introduced today, but fortunately there are different friends have these two headphones (of which the FIIL is the previous generation), to compare back and feel FIIL DIVA will be better.
The first is to buy a new do not buy the old reason, followed by FIIL DIVA smaller than Sony's, especially the experience after folding storage, and finally in the sound quality is not worse than Sony's (my ear level problems, do not spray!), while FIIL also There is a dedicated mobile phone app, playing a lot more than Sony, and finally chose FIIL DIVA. As early as the Dog East to buy, in the afternoon, in fact, the headset has been to the phone for nearly two weeks, the picture is also a good shot, there has been no time to organize the upload, take the opportunity of the National Day holiday to share and feel.
Originally wanted to buy a black, but think about black touching that fingerprint, and finally bought a white, the following is part of the open box picture (from the broken cell phone and unprofessional cameraman):
The courier box did not take home and was directly on the official packaging.
Nothing can be said about the packaging, the white box, the most obvious is the "Hi-Res AUDIO" logo
Sweeping the QR code is an official app for everyone to download and install FIIL. Sweeping will not be pregnant. . .
There is also a headphone bag inside, so when you go out, FIIL is still a conscience.
Below the headphone package is the charging cable and the headphone cable, which is the same as the data cable of the Android phone, so I'm useless. I don't intend to use a wired connection, so the headphone cable has not been opened. . .
The body of the earphone is quite small and compact, and it can't be seen as a wireless earphone. After all, the wireless module and battery are added inside, and the volume control can be achieved, which is even smaller than a generation.
Especially like the headless beam of this stepless adjustment, the plastic above it is also very comfortable
The main buttons are designed on the right side of the handset. In addition to the switch/pairing button, there is a push button that was originally thought to be just volume, which I thought was too simple. This is a noise canceling button, also known as the MAF (My AudioFiiler) button. The patent of FIIL (it seems to be very interesting). Single-click is to open and close, sliding left and right is to adjust the noise cancellation mode, there are three modes of open, monitor, noise reduction.
The right earpiece is also designed with a sliding touch function. Sliding up and down is to increase or decrease the volume. The left and right slides are the adjustment of the front and rear songs. There are cases where they are inadvertently touched. It takes a while to use them.
The packaging still explains what, but in fact we all know that I will not look.
I also mentioned that FIIL has its own mobile app. This is one of the important reasons why I choose it. Fruit mobile phone users can download the fiil+ app from the app store.
Open app, in addition to the need to select the corresponding product model, will also prompt to enter the serial number of the product, become certified users
In addition to this app will display the power of the headset (the upper right corner of the iPhone itself will have a display), and the other one is more interesting is to provide the function of the headset, only open this feature, the app is to automatically play the contents of the device, adjust the appropriate volume, All of them are automatic, suitable for me as a lazy person, but the whole process of taking the machine takes 3000 hours. Is this a joke with me?
Said so much, finally need to comment on the sound quality of the headphones, first of all I am not a headset fever machine, the sound quality requirements are not high, or will not choose a wireless headset, so I was quite satisfied with the sound quality. He himself mainly looked at the wireless noise reduction function of FIIL DIVA, which was fairly satisfactory in both areas. Because I was mainly connected to a computer at home, I didn't care much about endurance. With moderate use, I was able to charge my battery once a week. The overall price in this price is a good choice.
Photovoltaic inverter (PV inverter or solar inverter) can convert the variable DC voltage generated by photovoltaic (PV) solar panels into an inverter of mains frequency alternating current (AC), which can be fed back to the commercial transmission system, or for off-grid Grid usage of the grid. The photovoltaic inverter is one of the important balance of system (BOS) in photovoltaic array system, which can be used with general AC power supply equipment. Solar inverters have special functions for photovoltaic arrays, such as maximum power point tracking and island effect protection. Photovoltaic inverters usually consist of the following main parts:
DC input: The photovoltaic inverter receives DC power input from solar panels.
Inverter module: The inverter module is the core part of the inverter, responsible for converting direct current into alternating current. It contains multiple electronic components and switching circuits, through precise control and adjustment, convert direct current into alternating current of specific frequency and voltage.
Controller: The controller monitors and controls the operation and performance of the inverter to ensure the stable operation of the inverter and make optimal adjustments when needed.
Output: The output of the inverter is alternating current, which can be connected to household appliances, industrial equipment or incorporated into the grid to supply electricity.
