In fact, as long ago as the rumors that the iPhone 7 will cancel the 3.5mm audio interface, I wondered whether or not to get a lightning headphones to play.
Of course, this is not just a fashion, as a fake fancier, pure digital interface output is indeed a good picker excuse ... Well!
So when I watched a Lightning headphone launched by a domestic startup company on Taobaozhong, I was wondering whether I should try fresh!
I was placed on the first day after the crowdfunding began. I was thinking that in accordance with the 30-day cycle of general crowdfunding, I should be able to catch up before iPhong 7 was released. The result was blinking and I did not see that the actual cycle was 45 days. ! 45 days! 45 days!
As a result, shipments did not begin until the day before the Mid-Autumn Festival, and then the holiday began just three days.... Today, it was only a small parcel.
The parcels were opened, and even the packaging of the headphones had not been removed. My heart was already in the grass mud horses... Headphone crowds raised 49 yuan, and +10 yuan sent more than one dedicated headphone storage box. Dedicated your sister! Clearly the kind of hard box Taobao 5 dollars, and even LOGO are too lazy to print up, on this virtue actually dare to sell 10 dollars! Bad review!
The headphone's box is very small, and it is known by comparing the storage boxes next to it. The basic style of packaging is to copy Apple's, and even I suspect that the above product photos are directly copied over. Reasons I will say later.
The upper and lower openings of the box were also affixed with an adhesive seal on top, until this moment I still hold a pure desire, I hope the quality will not be so bad.
On one side of the box is company information, and on the other side there are a recycling mark, CE certification mark, a few lines of birds, and the usual two-dimensional code.
Open the package, inside the headset is also packed with film PE bags, thick smell, I would say that this packaging is also better than the first three of the first 9 headphones only a little bit it? !
Retired that layer of film, finally exposed the body of the headset, I am more sure that this is the level of roadside booth 9.9 ... ...
The appearance of copying the Earpods is no problem. This is a time when crowdfunding was already expected. The problem is how the huge remote control is all about, and the whole headset can be said to be not in tune!
Guess who is the "Li Gui". In fact, you don't have to guess it. You can easily distinguish it from the workmanship by looking closely. This headphone's mold work may not even match the high imitation Earpods, especially the soft rubber between the shell and the wire is obviously rough and inferior.
In addition to the wire, the wire used in the original Earpods is not as thick, but the only wire used in this headset is more slender - but in terms of feel, it is harder than the original Earpods, so wear it The ears will be even more disobedient and will easily shake with the movements of the body.
As for the front Tucao wire control, apparently larger than the original full 2,3 laps, and the key feel, the middle confirmation key with the volume + is still crisp, but the volume - a little feel, I am afraid is the assembly process problem.
The other is the lightning interface. In front of me, I dared to assert that the picture on the package is a direct copy of the apple instead of the product. Take a look at the official and you will know... The right one is the original specification, that is, the one on the package. appearance. As for the left ... ... Oh!
Although the light-only digital audio output interface needs to have a corresponding DAC chip for conversion, today's DAC chip has been made very compact and can be integrated directly into the lightning plug. I did not disassemble the headphones, but judging from the size of the lightening interface, the DAC chip should be in this area rather than the online control (of course not wrong). However, the socket is so thick, there is no corresponding ladder design, hit the set of mobile phone equipment is doomed only cup!
As for sound quality, I was originally going to compare it with Clarity Feather Hi-res Notebook DAC+Earpods...
The result is plugged into the iPod touch, and open NePlayer a look, although the 48kHz support, but playing a higher specification 1bit/2.8MHz DSD format file can only run 44.1kHz, which with my direct plug 3.5mm audio output there is a What is the difference? !
Even if you leave this alone, light from the performance of the sound, we all know that Earpods headphones in the hundred-dollar level can be considered very good value for money, although the sound density and dynamic aspects can not be compared with professional headphones, but it is higher than the average machine with s level. And this crowdfunding headset, frankly speaking, I know that the opening of a game, rough, fuzzy, heavy grain, high-frequency plucked low-frequency muddle frequency into a pan of porridge, take it with the aforementioned A50 feels to make the other party more prominent Value, to know that people only sell 3 9~!
In fact, some time ago, his own work just happened to be busy with crowdfunding projects. Therefore, he also contacted platforms including Taobao’s public fundraising. He also learned more about the dark side behind this wave of crowdfunding projects in China, but he really didn’t understand why the foreign public Although there are a lot of pits for the fundraising projects, Haoxi has successfully hatched a number of startups and brands. However, domestic crowdfunding has basically become a roadside stall for sellers selling various goods.
Although dozens of dollars are not really many, but the business name of "with the same level as two or three hundred headphones," flicker to the buyer, even if you only sell five 9 is also disappointing and angry.
What's more, even if you are disappointed and angry, you won't have any impact on the results. Even if the merchants change their accounts and hang another gimmick, they can go on crowdfunding. The reality is so cruel!
So, in the end, we advise you to value your friends, raise funds, and be cautious!
