Since the VIVO xplay 3S, has been very dissatisfied with the mobile phone sound quality of the opponent's head, used Meizu MX4 Pro, hammer T1, are known as HIFI, the actual listening to know and VIVO gap is still very big, the hammer T1 HIFI can only Use your own player. Not long ago in the digital to see more rhythm tanks new product evaluation, product positioning is in line with my needs: both to improve the sound quality of mobile phones (unbundled out of the party), but also as a PC / notebook external sound card. Jingdong crowdfunding price of 488, as well as headset bundled suits, if it happens to demand, 1588's iron triangle MSR7 bundled suit is also cost-effective. Received on January 7, had to Tucao this crowdfunding. The outer box is the rhythm tank itself, not packaged by the courier company, so the inner box is so broken that this pot must be rhythmically back. The black box is of poor quality. What's more serious is that the lid is very tight and it takes a long time to go. After opening the box, the upper layer is iDSD. The lower-level mobile phone manufacturers have developed a small boxed data cable and instructions. Then the white cartons underneath are too tight to be taken out. The only way is to destroy the packaging and remove the violence. . . All accessories family portrait, an ordinary Android OTG cable, a type C OTG cable, a T-port charging cable (Mini USB port for USB2.0 mobile hard disk, Micro USB port for non-general Android phone), two A completely useless plastic ring. The accessories were stained with black dust, and the two white plastic rings were almost gray, throwing trash directly. From left to right, the front is the power switch, power indicator, American standard 3.5 headphone jack, and national standard 3.5 headphone jack. From left to right, the back is the T-type charging port (Mini USB), the data port (Micro USB), and the standard USB port (the standard IOS, but it does not actually find any use). Side is the volume key. After downloading the official website driver, the current playback device is set to iDSD by default. The following devices pass the compatibility test: Win10 64bit + official website driver; Hammer T1; One plus 3T; Ipad air 2; Iphone 6; Win10 insider fast + native UAC (USB audio class 2) driver; Android requires Seashell Music to output via USB audio normally. Other APPs may not be available due to lack of USB audio function (Netease Music does not support this, but similar to Poweramp or some mobile phone manufacturers native app if you support USB audio features, maybe Can be used, due to limited hand equipment can not be verified). The IOS family should be okay with the same audio architecture, and no sea bass music is needed. You need to bring your own lightning cable. Since the lighting adapter cable is a standard USB port, you can use a regular Android data cable to connect the iDSD data port to the standard USB port of the extension cable. Then the right side of the iDSD is marked with the IOS standard. What is the USB port? The MAC is not on hand, but the Apple family can use it as long as it supports UAC. My one-plus-two pro-test does not support, for testing, the official native hydrogen system (Android 5.1) brushed to the official hydrogen 2.5 public beta, and then brushed MIUI, FIUI, magic and other various third-party ROM, are tested failure. At that time, I wondered why the brothers at the same level were supported by one plus three. One plus two would not support it. There is very little information on the Internet in this area. The Forum also saw that there are not enough external DACs to support external DACs. Later I found an article on a foreign website to the effect that one plus three did not use the standard USB Type C specification, resulting in no support for external USB devices. This problem started from one plus two, one plus three repetitions. Later, an option to support OTG was added to the setup to make up for this problem. But one plus two when I opened the open is useless, one plus 3T to open the OTG switch on it. In addition Lumia 930 + Win10 mobile insider fast does not support, before there is to look like a Lumia 950 this support for external USB devices, the phone is to support UAC, not on hand can not be tested. Here is a simple addition to the front panel of the first and second earphone hole, the former is the national standard, the latter is the American standard, the difference is to see the earphone 3.5 connector is a white ring or a black ring. Let's talk about the use of these days and some problems: Turning the power switch to the left and right is not very crisp, and it is easy to move in the neutral position; The built-in lithium battery in the iDSD itself has the advantage of eliminating external power supply instability as much as possible, but the built-in battery has small capacity and is not strictly tested. It is estimated that it takes three to four hours; The T-type USB charging port is definitely a big design flaw for iDSD, because you have to go out and charge this line that is almost eliminated quickly. The Micro USB port in the middle of the test can't be used to charge the computer. In addition, during the charging process, the power switch is disabled and the device is always on. In other words, if the computer is used as an external sound card, if no power is available, two USB cables must be connected to the computer to continue to use it. Charging cable to USB charger); The Android mobile phone can be used directly by using the OTG short line that comes with it, so it is convenient to bundle the party. For IOS, please bring your own lightning cable; Part of the sound quality, refer to the digital evaluation, roughly the sound quality than the poor state of the 02 dragon card strong, worse than the 06mx, big level or push box gap will be greater, but generally speaking only sound quality is still very strong, It is very obvious to improve the sound quality of the mobile phone, or as a desktop external sound card, the integrated sound card is greatly promoted. I test with the vivo xe800 earbuds and Philips SHP9000, time is hurried, but the overall sound quality is quite satisfactory, the speakers have not been measured, I feel that this is not necessary; The product itself is very light, but remember to bring out all kinds of lines when you go out, and one of them will cause problems. Since most Net Music apps such as Netease Music are not supported, when listening to a mobile phone, they can only listen to local songs and cannot listen to online songs (does not rule out the fact that mobile phones support global external USB audio, such as Apple’s native support of UAC, Samsung’s international Branded Android phones are often integrated, but they cannot be tested.) Have to spit out the trough of the crowd to pick up the packaging work, is completely baked small workshops, mold rough, button stiff, other crowdfunding users have also reflected workmanship cottage. For purchase suggestions, personal opinions are: If you happen to need to improve the sound quality of your mobile phone or occasionally use a portable device for an external sound card, and the actual selling price is lower than 600, it is worth purchasing under the premise of improving product packaging and QC (quality control); If you only want an external sound card, or have a high demand for the appearance of the product, or if you use one plus two like me, then iDSD is not recommended; In summary, considering that the sound quality is the core value of the product, LZ still has a positive attitude toward such a product. Although there are too many unsatisfactory areas, after all, the price of crowdfunding is not high, and the corresponding disadvantages can also be achieved. Endure and understand. Digression Domestic manufacturers' QC (Quality Control) really needs time and money to improve, because it is also an important part of the product and has a very important impact. Last week, I went to one-plus-one domestic private-owned enterprises to carry out the factory inspection of the equipment. I had to lament that the large and wealthy private enterprises were too weak in this respect. They were not entirely on line with international companies. The office building was like a four-star hotel. It looks very good, but QC is simple to almost nothing, and the last product has a problem. The customer starts to get a headache. QC, QC, QC. . . This is one of the necessary conditions for domestic companies to go international. . .
