First, the first thing to do is to observe the purchased outer packaging. When unpacking, the genuine box is covered with transparent tape. Authentic tape should be clean and sticky, and there is no trace of repeated pasting. The transparent cover of imitation is easy to open, while the genuine one needs a little force to open it. The white chassis of the genuine box is closely connected with the transparent box, and it will not fall off when it is turned over. In addition, the groove of the storage box may be a little different, as shown in the figure, the groove of the imitation will have a connection seam, but there is no genuine one.

Second, check the seams. Apple adopted an integrated molding process many years ago, with excellent workmanship, and there is absolutely no rough or even misplaced gap on the whole earphone surface. Carefully check the following edge seams. If there is such a gap, it means that you may have bought an imitation.

Third, Wang Qiwen is about 250px away from the socket, and there is a tiny line of words (be careful not to stare for too long when observing, which will damage your eyesight). There is a space between "California" and "Assembled", and there are two spaces between China and the following serial number "DTX…". Check these two places, and you will find that imitation is more or less empty.

Fourth, listening to headphones is the most important thing, but if you don't have the ears of an enthusiast, try this simple method. Plug Earpods and headphones into iPhone5 and play a piece of music at will. Hold down the two vertical earphone holes shown in the figure with both hands. If you find that the sound is dull, the bass is weakened, the sound is ahead, or it becomes less heavy, then this earphone is genuine, and vice versa. If the change is not obvious, you can try again by pressing the vertical earphone hole at the top of the earphone head. Or turning up the volume can make this change more obvious. This is because the air hole design of the earphone is unique and conforms to the hydrodynamic specification. The air hole at the back is used to stabilize the sound, and the two air holes at the bottom are used to enhance the bass in the cavity. For the cottage manufacturers, it is just to imitate the shape and open two holes. Of course, covering it with your hands has no effect.
