FiiO's product line has always been dominated by players. Since the appearance of the FiiO M3, the earbuds that were randomly distributed have attracted my attention. At the time, I gave it a rating: Conscience! Then I wondered if FiiO would officially begin to enter the field of earplugs. Sure enough, FiiO officially launched its own first earplug: the FiiO EM3. This plug uses a flat head plug design that is not very common at present, and continues to take the conscience route on the sound, 88 yuan plug.....think I used the value of 180 when I started the headset 13 years ago. Diversified Sennheiser MX500! What is the performance of this stopper? Please also take a look at my experience with it. This plug's impedance is very beautiful, 47 ohms! According to the official statement, the improvement of the impedance can change the impedance characteristics of the earphone and reduce the nonlinear distortion caused by the inductance components in the earphone coil, thereby effectively improving the sound quality. This impedance is actually not very high compared to some real high-impedance headphones. The main consideration is that there will be many users using mobile phones in the price range of 88 yuan. Although the FiiO EM3 is cheap, it is still relatively elaborate on the packaging. The new design of the packaging, whether it is the appearance of the box or the internal structure is different from any of the earplug products, it still looks very good. There are not many things in the box, except FiiO EM3 left a piece of paper. I think the sponge has to provide a pair, right? After all, for flat head plugs, the effect of sponges on sound changes is still very large. As an entry-level flat head plug, the use of plastic in the shell must be a matter of reason. The workmanship is so-so and the weight is light, and it is more comfortable to wear in the ear. The metal filter gave the earplugs an overall enhanced sense of grade, and there was no visual glue spillage. The performance was considered good. Taking into account the needs of mobile phone users, FiiO EM3 equipped with a remote control module, using it to bring mobile communications is also more convenient. In addition, an L-shaped socket is used in the plug part, which plays a crucial role in the protection of the cable. During the audition phase, I used the FiiO X5+FiiO E12A for the experience, so the tracks are in WAV format. The first impression that FiiO EM3 gave me was that the analysis, resolution and permeability performance was very comfortable. Thanks to the flat head plug's open design, it sounded very open, even in the absence of oversight. in this way. The overall direction of the sound reminds me of the MX300 of the year, but the MX300 has a big drawback. It is a thick plastic feel. On the FiiO EM3, this plastic feel is completely absent. In terms of vocal expression, the performance of the resolving power has always been good, not fat and greasy. It is estimated that it is an entry-level user's experience. The vocal sound is more abrupt. The high-frequency part of the female voice is slightly toothed and the ductility performance is not excellent. But using it to listen to vocal-based works is still very pleasant. In the expression of pop music, transients and low frequencies are two very important factors. FiiO EM3's low-frequency dive is not very deep, but it is still good in terms of cohesion. So in some rhythmic tracks, it will not The sound is too thin, and the transient performance is also good. So I think the FiiO EM3 is still very comfortable and comfortable to interpret the little love song. Summary: As a $80 flat head plug, the overall performance of the FiiO EM3 is all that everything seems to be extremely mediocre, of course, this is understandable, first of all the price factor is here, and then I feel this plug Some of them have, although the limitations of sound quality are relatively large, but there is no phenomenon that can only express certain types of tracks too much. The size of all-you-can-eat, any song can let you listen to it quietly without feeling uncomfortable, this kind of tuning style is extremely easy to choose. All in all, the FiiO EM3 is a stopper that is resistant to hearing. It is not irritating but does not want to be boiled. There is a gentle tenderness in the tenderness. There is not much that can be done in a hundred-dollar plug. FBT (fused biconical taper) is the traditional technology in which two fibers are placed closely together, typically twisted around each other and fused together by applying heat while the assembly is being elongated and tapered. A signal source controls the desired coupling ratio. The fused fibers are protected by a glass substrate and then protected by a stainless steel tube, typically 3 mm diameter by 54 mm long. FBT splitter is widely accepted and used in passive optical networks.
