I once had a bad friend in high school told me that if your car has abnormal noises and loudens the sound of music, then you will not feel any abnormal noise. It is quite Chinese. The same theory was applied to the headphones, and it used to make me think that headphones must be noise-reducing. Wouldn’t the music be loud enough to hear the noise around? Until you try Bose's active noise canceling headphones, you will realize that when the sound is loud, you can't hear the noise around, but the noise will be there, and it will damage the hearing. The first contact with Bose was when I bought the Bluetooth speaker at the beginning of the year and I bought the Soundlink Mini2 to my relatives. At that time, it happened to be a promotion. There was HKD150 at the Bose store in Hong Kong and finally it was HKD1650. Although there was no Haitao so favorable, it was able to get it and it was guaranteed. (Strictly speaking, the first contact with Bose should be on the cousin's Lexus, but at the time it wasn't quite known about Bose's tact.)
Pulling away, he has been completely conquered since he bought his home Bluetooth speaker. Of course, he has been paying attention to his family's products. However, he has not been thinking about the product until Bose announced the QC30 in June of this year. When the iphone7 has not announced that it wants to cancel the analog audio interface, but fortunately I think the wireless is the future trend, so first try to buy the water Meizu EP51, feel the Bluetooth headset is suitable for me this is often a business trip to run People who went to wear, although not wearing Bose that kind of StayHear + so comfortable, but still make do, not to say Meizu's not good, buy this headset is also a daily wireless convenience, but may be such a headset line design Bottleneck, when you wear it, you can't use force to turn it, otherwise you may tear off the headphone, so it is always inconvenient to turn around.
After the process of waiting also almost forgot the QC30, until the last two weeks to buy iphone7 by the way through the Bose specialty shop in Hong Kong to see the QC30 in kind, was told to book in advance there is a T-shirt, a Bose's home Travel chargers have an extra one-year warranty to send because they haven't confirmed when they will be able to pick up the goods, so they haven't booked them yet. They have been brushing Bose's official website for a while but they haven't said when they can buy it. After another week of dealing with her boss, she passed another Bose store and was told that she would be ready to take delivery on the 10th (at the time it was number 6). At the scene, she tried to comfortably use the new QuietControl function. It was booked without considering how long it took. The official price of Hong Kong was 2588, which was equivalent to 2235 yuan at that time. It is definitely more expensive than the US official website, but the key is that I will not travel to the United States, so buying in Hong Kong is best for me. At the same time, Amway’s Bose stores in Hong Kong, although their products will not lower prices than usual, but wins in some quarters will launch some promotions, free time you can pay more attention to their official website.
As a result, on the 11th, the clerk notice was not received and he called to ask. He was informed that because of my lateness, the arranging of goods for the guests who booked in advance was estimated to take one more week. On the occasion of loss, I didn't expect that the person who left the store today would arrive, but the gift had not yet arrived. He could take the headset first and then inform me to come and collect gifts. So almost immediately went straight to the store, let it go home and out of the box.

The mobile phone APP is connected to it, it is very convenient, and a keystroke can also be used to eliminate noise
Talk about the use of feelings, because it was unpacking at home, so did not try on the subway or on the plane, especially at home around the mall a few laps. In terms of sound quality, I really don't understand such things. As long as I don't feel bad, I don't think the sound quality is good for me. Most people buy this half in order to silence half of their beliefs... In addition, switching off the music when the store tries QC20 will have a clear current, and QC30 does not have this problem.
Many people also know that so-called noise canceling headphones are not 100% noise-reducing, and they don’t want to buy 100% noise-reduction. After wearing it, you will still hear a few voices and some sharp voices. The wind noise may be due to the fact that other noises have dropped. People feel that wind noise is relatively obvious, but it's just a bit. As for the flagship QuietControl feature, the personal feeling is not as good as the QC20's one-key transition between noise reduction and the aware mode. At least for now, I have not encountered any scenarios that require 20% or 50% or 80% of the time. Noise reduction levels either completely eliminate noise or do not eliminate noise. It is really easy to use when you turn off the noise cancellation mode. You don't need to take off your headphones, and you have no problem communicating with the people around you. You are also not afraid of making your voice louder and scary because of too much music.
The inconvenient place on the QC20 is that unlike the QC35, there is an additional cable to connect the traditional 3.5mm interface, so when the headset is out of power or when it is on the plane, it is more embarrassing.
Regarding the headset as a dog-dog problem, in fact, I was not worried about the appearance at first, but the degree of comfort. To know that the QC20 also has a box that is responsible for putting the battery and processing chip (which is also responsible for the radio?). What Bose has to do is put the box inside the dog's ring. It also needs to take into account the appearance and comfort level. To be honest, Although I'm not designing, I don't think it's easy anymore. At least I think that unless there is any black technology, noise cancelling headsets can't be the type of Bluetooth headsets in Airpods for nearly 5 years. After all, It is a noise canceling headset. The design of this dog ring also perfectly solved the problem that I just said that the Meizu headset turned around. At the same time, this design also avoided the need for most Bluetooth headsets to place the battery on the remote control to make the headset particularly heavy, resulting in a headset being Tugging discomfort. And this dog circle is still surprisingly light, and it's almost impossible to wear it. What is more worrying now is that this ring or the headset itself will not corrode the sweat. Although I certainly do not wear this sport, I am also thinking that people who sweat more often wear it around and walk around. Sweating, I don't know how big the impact is.
When it comes to comfort, the Bose patented StayHear+, also known as a shark fin design earbud, is the earliest and most stable earplug I've ever tried, wearing no discomfort.
As for the price, the old saying goes, people who meet someone are already so difficult, why not buy something that they love. Doesn't it be impractical for the poor to buy Ferrari for enjoyment? What's more, Bose's product prices are firmer than iphones. I used to think that this price is too expensive for a pair of headphones, but the price is not a GTX1060. If you think of the balance here, the video card may be upgraded for a while, and you can't just Buying a video card will open the game, and the enjoyment of quiet music is relatively immediate. Although I rarely fly, I will usually go on high-speed rail every week. The noise from the crying and the aunt is more annoying than the sound of the engine of the aircraft. Therefore, the QC30 is really a good news for me.
Finally, to share a joke heard on the Internet, “Cheap things are all kinds of shortcomings besides being cheap; expensive things are all kinds of advantages besides expensive; many shortcomings are one disadvantage and therefore expensive. You have no disadvantages, but there are "Tears: Can't afford it" This view may be a bit extreme, but it still makes sense, and I think that what you buy is not a step-by-step thing that is a waste of money. This person's insights have been experienced after you bought 16Gb iphone5s. ...
Fiber Optic Patch Panel(ODF)
Fiber optic patch panel is now widely used in networks and it is an integrated unit for fiber management, we are offering various kinds of Fiber Optic Patch Panel, such as wall mounted fiber optic patch panel, rack mounted fiber optic patch panels. These equipment functions to fix and manage the fiber optic cables inside the box as well as provide protection.
Our wall mounted fiber patch panels accommodate up to 8 modular panels and is equipped with routing guides to limit bend radius and enhance strain-relief control. The 16-gauge steel with corrosion-resistant black powder finish coat housing provides excellent protection for the inside fibers. Wall-mount available unloaded, as well as having the capability to become a full-splice enclosure with mechanical terminations. A large variety of connector adapters are offered to meet your specific requirements. Such as SC, FC, ST, LC, etc, we can also pre-install various kinds of fiber optic pigtails inside the patch panel.
YLTelecom offers a series of changeable inside panels to fit for different kinds of the adaptor interface, and fit for both round and ribbon fiber optic cables. Our rack mounted fiber patch panels can be drawer type or economic type without draw design.
A Fiber-Optic Patch Panel is used to separate out the fibers within a fiber-optic cable. By using one of these panels, the fibers can be spliced to individual fibers on other cables, allowing the cables to be crossed and connected in a variety of ways. In addition, the panel creates a safe environment in which to work with exposed fibers.
There are two main types of Fiber-Optic Enclosures. One is a wall-mounted device, which, in its most basic form, can keep 12 different fibers separate from one another. If the fiber-optic cable has more than 12 fibers, the extra fibers can be moved to a second panel or an engineer can use a panel that is designed to hold more fibers separately. Wall-mounted panels can be constructed to hold up to 144 fibers at once.
The other type of Fiber-Optic Patch Panel is a Rack-Mounted Panel. This type of panel holds the fibers horizontally and is often designed to open like a drawer. Sliding the panel open gives an optical engineer easy access to the fibers inside.
