First of all, please ignore this messy disc and slag focus. It hasn't been put on for a long time. It is a long time to get the camera out of the moisture-proof box. I have thought about this earphone for a long time, mainly when it comes to roller skating. There are already countless wired earphones in the jump, and I am cut off during the running, crushing... all kinds of dead methods are there, early When I used the Sony Q25 for some years, I felt that it was the most suitable. Although there are ropes, it is easy to not fall, and I can hear the environmental sounds. Unfortunately, it will not be out later. In fact, the big ear hooks can put a lot of batteries according to the current technology. However, Sony does not live up to expectations, and later Sony's w273 and other ear mp3 design is good, but I do not want mp3, Sony you will make a Bluetooth headset will die?
Well, I’m far away. I first wanted to see this earphone. First of all, it won’t fall. My ear hole should be with my dad, one with my mother, no matter what shape, the left ear is always very It's easy to fall, so I like ear hooks the most. I used the EC7 of the Iron Triangle for a long time, but I was broken by the line. This is good, Bluetooth is finally free.
After the earliest US listing, the mainland did not. I went to Hong Kong two months ago. I haven't found it for a long time. I have a purchasing on Taobao, or I am lazy, too lazy to toss. Today I went to the Lujiazui Apple Store to repair the computer. I just saw it, the clerk Said that it should be the goods that arrived this week, decisively won, 1598, should be much more expensive than Hong Kong, forget it, buy early and enjoy early.
Pseudo-opening the box, because I have already opened the test in the Apple store, connecting Bluetooth quickly.
It's a plastic cover on the top, it doesn't look like the big one in Studio.
The material is still good, the ear hanging legs are soft, it is very comfortable to hang on the ear, and the whole is very light, hanging on the ear without any burden.
All things are like this, only the charging cable, no charging head, I haven't read the manual yet, I don't know how much current to charge. For safety, I still charge it on the computer. The box with the headphones is even more without the Bigger in Studio. Although the materials are exactly the same, this type does not feel round enough. In short, there is no bigger, but it still feels good.
There is a volume adjustment and switch on the earphone. This is better than a wired studio, because the wired studio is plugged into the Android phone. 1. The volume adjustment is useless. 2. It is useless to press the key to cut the song twice. But this wireless, even if connected to the Android phone, you can adjust the volume on the headphones, you can double-click the key to cut the song (I tried note3, the music software is shrimp), so you don't have to rush frequently when you run. The phone came out and finally liberated.
These sponge sets have not been tried yet. I have been wearing them for 2 hours and I still have no discomfort.
The charging cable is Micro USB, which is convenient for general use.
In addition, I also bought my black battery today. This black has been in service for 7 years. The battery is already in a state of automatic power hibernation. 7 years ago, the machine also had accessories to buy, and Apple is quite hard, but This machine is still tossed, before I added the memory to 4G, the optical drive changed the big hard drive, the hard drive changed ssd, the speed is still just now, now even the two hard drives to do the download machine.
Finally, why do I want to put this picture? I want to praise the after-sales of beats. Since the breaks of the beats and the magic sound, there is no after-sales in the country. All the after-sales are American, and the sponge of my previous studio is opened. So, I called the Americans. It is a domestic 400 number. It is transferred to the United States. It doesn't speak English. No problem. I will come to a translator who knows Chinese. Then I will talk about it. It is a sponge cover. Cracked, it should not be a year, people let me go back to find a small ticket, and so on, because I was a friend to buy at the US airport, the small ticket has long been thrown by me, so after a communication (also Chinese mail) Back and forth), I said that credit card bills can't work, people say it is OK, ask friends to ask for bills, there is actually no product name on the bill, only one store in Chicago airport, but fortunately, the card is more than 200 dollars in this headset, I circled out and said That's it, print it out and take a photo with the headset, then say it is submitted, reply to me a few days later, the submission is successful, give me a new one, and, say, considering the postage to China is very expensive, the old You don't have to send it back! So I will be I used 502 to stick the sponge cover, 502 plus a small tweezers, a little sticky, my craft is good, but I can't see it at all, so... After four or five days, Fedex sent me a parcel, of course, not A full set, no box and earphone bag, so I have two studios, this is really enough for the after-sales. Perhaps, this is why I continue to support his family.
Finally, the sound quality, in fact, I think the headphones still have to be under the Fort, otherwise it should not open, the bass should be a little thicker after the Fort, but no matter how you do not need too high sound quality of the Bluetooth headset, it is not used for pure appreciation Music, it is best to handle the sound insulation to the right. For the test of anti-sweat and water, let me wait for my sports.

Phase Inverter and Single Phase Motor Manufacturer are two important parts of the power sector. Their definitions and importance are as follows:
Phase Inverter: A phase inverter is a critical piece of equipment in the power system, whose main function is to change the phase of the power source. This is especially necessary in many applications where there is a need to convert a single-phase power source into a three-phase one. This conversion allows for a more effective utilization of power and can provide more stable and superior performance. Phase inverters find their use in many industrial applications, heavy-duty equipment, and certain specific household appliances.
Single Phase Motor Manufacturer: Single Phase Motor Manufacturers form a vital part of the motor industry. The motors they produce are mainly driven by a single-phase AC power source. The advantages of these motors include their simple design, lower cost, and ease of maintenance, thus making them very common in low power devices such as household appliances and small industrial equipment. However, for devices requiring a large amount of power, more complex and powerful three-phase motors are usually used. These manufacturers not only produce these motors but are also responsible for research and improvement in their performance and efficiency.
Both of these sectors form important components of electrical engineering and the motor industry, providing indispensable services and equipment for our everyday life and industrial production.
