When the flat head plug is used with beryllium-plated moving coil-experience feiao EM5 flat head moving coil earphone

maybe every little partner who has been playing with Walkman for some years will have deep feelings for flat-head moving-coil headphones (flat-head plugs). Because there were no in-ear earplugs when we first came into contact with the Walkman, Walkman plus E818 (Sony classic plug) has almost become the standard for everyone. This combination has brought us many touches from music that cannot be surpassed until today, leaving us a deep impression.

Since the appearance of in-ear earphones, they are more suitable for the scene of "Walkman" due to their better sealing and sound insulation. They have gradually replaced flat head plugs and become the mainstream of portable earplugs. With the development of science and technology, they have not only derived a new category of iron unit earplugs, but also evolved the unit materials of traditional moving-ring in-ear earplugs, for example, the recent beryllium-plated moving coil has a very good performance on FH7, FD1, and FH3. The flat-headed plug is carrying the banner of feelings again and again, re-engraved with ancient molds and traditional units, and fade out of the vision of Walkman lovers.

, in fact, I don't quite understand why Feiao had to make a flat-head earplug like EM5 at this time, but EM5 attracted old Walkman players/digital enthusiasts like me as soon as it appeared, because it not only looked like a new thing at first glance, but also carried many star auras: highly praised beryllium-plated moving coil, 3D printed skin-friendly resin seamless mold, low-frequency acoustic flute tube design, and. Let me look forward to how it will perform.

Exterior & Accessories

Due to the use of 3D printed translucent resin and low-frequency acoustic flute tube design, the appearance of EM5 is obviously different from that of the traditional male mold flat plug.

looks good or not varies from person to person. Personally, I think it gives me more of a novel feeling. The integrally formed earplugs are smooth and have no stitching. Through the earplug shell, you can also see the internal simplified structural design.

Feiao EM5 uses a 14.2mm beryllium-plated moving coil unit. The same type of moving coil unit has been applied to in-ear earplugs such as FH7, FD1 and FH3. Due to the high rigidity and low quality characteristics of beryllium, the beryllium-plated moving coil can have stronger vibration amplitude and faster vibration speed, thus bringing more surging and faster response low frequencies.

Due to the structural characteristics of the flat plug, it is not suitable for replaceable wire design, so Feiao EM5 is directly equipped with a high-purity pure silver wire at one time. The wire of EM5 put together with other wires is the whitest and brightest, and looks very advanced. Silver has good conductivity and has a certain effect on resolution and high frequency.

Although Feiao EM5 cannot change wires, it can replace plugs and is equipped with 2.5mm/3.5mm/4.4mm replaceable plugs randomly, which can be matched with high-end players for balanced output. This way of replacing the plug is very convenient. I have always wanted to buy one of these wires, but the single wire needs 1298 yuan (similar to Feiao LC-RE upgrade wire). In this way, EM5 is really cost-effective.

replacement method is very simple. As long as you turn to the ON position, you can unplug the replaceable plug, replace the new plug and turn it to the OFF position to lock it.

as we all know, replacing silicone sleeve for ear plugs is the lowest cost and most effective means to improve (adjust) the sound of ear plugs. The flat head plug can actually adjust the sound by replacing the sponge sleeve. Feiao has provided a total of 18 pairs of sponge covers of 3 types for everyone to adjust the sound of earplugs according to their own needs to achieve the best condition. Including 6 pairs of low-frequency sleeve, equalization sleeve and permeability sleeve.

As the flagship earplug, Feiao also equipped EM5 with an HB3 leather storage box.

Sound Quality & Experience

mentioned earlier, the reason why in-ear earplugs can replace flat head plugs as the mainstream collocation of Walkman is because it has better sealing, can isolate noisy noise and bring better and more complete sound experience. And it is not completely without drawbacks, such as more discomfort in the ear, more pressure on the eardrum, and smaller sound field. On the contrary, flat head plugs are usually more comfortable to wear, the sound is looser, and the sound field is more open. However, the radical Feiao obviously didn't want to make a "normal" flat-head plug, which is why he inserted such an active large-size beryllium-plated moving coil. He also used the design of a low-frequency acoustic flute tube to greatly improve the low-frequency of EM5 compared with the "normal" flat-head plug in terms of quantity and diving. The pure silver wire improves the overall transient performance and resolution of EM5, while making the medium and high frequency of EM5 brighter.

careful friends have a row of small gray characters in the "low frequency acoustic flute tube" part of feiao EM5 's product introduction, "note: in order to obtain better low frequency experience effect, please use it with sea surface cover". In the actual experience, I felt the same way. Whether EM5 wearing a sponge sleeve presents two completely different sounds: EM5 not matched with a sponge sleeve has a clear and transparent sound, and the low-frequency sense of quantity is more than the "usual" flat head plug, but the sense of quantity is still less. Once matched with the sponge sleeve, even the most transparent sponge sleeve, the low frequency sense of quantity suddenly rushed out.

EM5 with a sponge sleeve will feel a bit between the "usual" flat head plug and in-ear earplugs. With the sponge cover, the sound insulation will be significantly improved, and the bass will appear more surging, but the analysis and diving will be slightly inferior to the in-ear earplugs. At the same time, because the EM5 with sponge sleeve has better sound insulation, the sound field will shrink a little along with it. In a place like Starbucks coffee shop, which is not particularly noisy, listening to songs with balanced EM5 can basically isolate BGM and noisy noise.

, I usually use a transparent sleeve and a balanced sleeve to listen to songs. If I listen to songs with a small sound pressure in a place that is not very noisy, it will appear that the low frequency is a bit fierce and a bit scattered. After the sound pressure is increased, the intermediate frequency and high frequency will obviously light up, which greatly improves the balance of music.

but in a quieter environment, I still prefer not to use the sponge cover. It should be noted that EM5 is made of skin-friendly resin, which makes it very smooth and difficult to fix it in the best position. Even if it is not easy to fix it well, as long as the wire is slightly pulled, the position of the earplug will change. Therefore, I also see that there are various small partners in the post bar who use insulating tape or Baibao glue to solve this problem. I also look forward to Feiao's introduction of a rubber ring that can be placed on the outer ring of EM5 to improve the wearing feeling without a cover.

I found a silicone ring with a flat head plug of other brands before, it can just cover the edge of EM5, but it will slightly block part of the bass relief hole. After matching this set, I immediately felt that it was full of flavor, not as thin as when I didn't wear the set at all, and not as fat and scattered as when I was covered with sponge. The three frequencies are more balanced and textured.

EM5 is more suitable for driving with a device with a slightly larger thrust than direct push to obtain a more layered and spatial sense of hearing, and give full play to the structural advantages of the flat plug. I usually use the K5pro on the desktop, the M11pro on the carry and the latest Q3 big tail to drive the EM5.

flat head plug will have a special bonus when playing back some songs. For example, this ACG golden song "The Car of Dawn" recorded in 2003 has a kind of poor recording under many modern in-ear Hi-Fi equipment, and the sound is not very good. But when you take out EM5 to listen, you can obviously hear a stronger sense of space and a better reverb. At this time, it is easier to feel the emotion that the arranger wants to express: Valkyrie, the Valkyrie in Norse mythology, drives the car of dawn and welcomes the arrival of the dead life every day. Although the sense of space is strong, the details of the human voice are still very clear. Nanli Yuka's distinctive timbre and the small tail after each long sound are vividly presented. After all kinds of complicated percussion music enter the arena, it appears to be very hierarchical and will not affect the main line of vocals. This is probably the best replay I have heard in the collection of "The Car of Dawn" for so many years.

, for some modern recorded pop music, EM5 brings more ear-sensitive and detailed vocals. The theme song of "Doraemon: Nobita's Antarctic Ice and Snow Adventure" by Ken Hirai's "Servant and Heart" is from "Doraemon: Nobita's Antarctic Ice and Snow Adventure". I first heard this song at the Doraemon theme restaurant under the sky tree in Tokyo. At that time, the feeling of listening to this song in the store and later with portable equipment was the feeling of being surrounded by this song. The voice of the human voice. However, when listening to EM5, I felt that Uncle Jian was singing with his ear close to his ear, and the piano was a little far away. The density of the human voice and the clarity of the details of the sound are far better than the flat-headed plugs I have heard before. The low frequency of EM5 is much stronger than other flat plugs, but when listening to some Hiphop songs with more low frequencies, people still have some expectations to make its low frequency dive a little further.

in terms of instrumental music, EM5 is more sensitive to piano sound, usually the piano sound will be slightly larger and the tone is beautiful. When playing "Tchaikovsky:Piano Concerto No. 1 in B- Flat Minor, Italian Capriccio & Flower Waltz", I can obviously feel that the piano is much closer to me and much better listening. The dynamics are also very good, and you can obviously feel blown up when playing in unison.

In general, EM5 is a somewhat special flat-headed plug when it can be worn better. When performing modern pop songs, it can bring ears-attached vocals and powerful analysis. When performing earlier recorded music, it can have a different flavor, retaining the characteristics of a flat head and a large sound field, but it also brings Strong quality. The low frequency is outstanding in moving-coil earplugs, but it is still slightly worse than in-ear earplugs. In terms of instrumental music, the performance of piano timbre and string momentum is outstanding and dynamic. All the above hearing feelings are based on EM5, which can be worn in a relatively suitable way, so I sincerely expect Feiao to be equipped with a non-slip rubber ring for EM5.
