What kind of sound can it bring to us in a single unit?
Since the moving iron earplugs and the moving coil earplugs are fundamentally different in structure, the moving iron earplugs are generally accustomed to winning in multiple units. Of course, this does not mean that the more the units, the better the sound, even the single unit movement. The earplugs also have a very good model, just like the enduring Etymotic ER4, even if it is a good product, it is better than the famous Kjs before, X10, now also has the Final F7200. Exquisite work.
If you look closely, you will find that these three highly-evaluated single-unit earplugs are designed with deep ear canal. The purpose is actually very simple, in order to make more sounds be perceived by your ears, thus making up for The low frequency defect of the single unit itself. However, qdc 1LE does not use the design of deep ear canal, then the low frequency performance can also be imagined. Like many single-unit moving iron plugs, the low frequency of 1LE is some "metal", the sense of hearing is more dry and not full. 
Golden Collection qdc 1LE 1st Anniversary Edition moving iron earplug experience
Last year, the biggest black horse in the domestic earphone circle was qdc. This brand has just gotten into the civil earplugs for a year and got a very high evaluation. It can capture the hearts of consumers. qdc’s own strength is naturally not weak. I have been making headphone equipment for military and professional fields in the past, such as military bone conduction headphones, hidden communication headsets, etc. There are also many singers in China who use qdc custom plugs, which is based on such solid strength. Basic, qdc will be able to follow the civil field. It is also the first anniversary of the establishment of qdc. In order to commemorate this moment, qdc also brought a very special commemorative earplug. It is the qdc 1LE first anniversary edition of the iron earplugs that I want to talk to the tail today. . Unlike the earphones of qdc, 1LE is a male mold earplug that can't be modified. A total of 888 pieces are sold in a limited amount. The number in my hand is 005, which is the first batch of goods. Not to mention the sound quality of qdc 1LE, it has decided its collection value from the limited sale. This earphone is the cheapest one in qdc's civilian plug. The entry is not so high. As for the plug. How, let's take a closer look. Let me talk about the price of qdc 1LE. The current official price is 1680 yuan. It is not cheap for a single-unit moving iron plug, and the official website is already sold out. People who want to listen. It is estimated that you can only see which line is offline or is in the hands of friends. The single-unit plugs that I have heard are not too small. Among them, high-end ones like the Final F7200 and the Jasper X10. The 1LE of qdc dare to sell this price. On the one hand, it is a limited edition product premium, on the other hand, it may be For a confidence in your own voice. Since it is a single-unit moving iron earplug, the volume must be relatively small, and it is a major feature of its convenience. The interesting thing is that the storage box attached to the 1LE is a heavy copper box. Plated with a layer of gold, the light looks at the shape design is somewhat similar to the feeling of a lighter. Texture, this storage box can be said to be good, but really want to say portable, I think it is not easy to use, the first is too heavy, the weight of the box is much higher than the earplugs; second, the storage method is very cumbersome You need to align the 1LE neatly in the storage slot inside. It doesn't matter at home, but it is a little troublesome when you go out. The official gift box I think is not for the user to bring out the street, but also some of the meaning of the collection, which actually meets the actual positioning of this earplug. The golden box, the heavy texture, and the ceremonial storage method are actually improving the collection value of qdc 1LE itself. Who wouldn't want a limited edition product to have a good collection method? This is also the case, really want to bring qdc 1LE out of the street, I think the ordinary zipper bag will do, of course, if you want to show off, then the original gold box can fully meet your needs, as if I am on the plane When holding the gold box to store 1LE, the uncle next door kept staring. In addition to this storage box, the 1LE cavity is still a copper-plated process. Because of its small size, there is no more than one. It is definitely no problem for everyday wear. However, considering the particularity of the material itself, it may be necessary to maintain it later. Be careful, I have some signs of oxidation on the surface of the cavity at hand. On the wire, qdc 1LE uses an oxygen-free copper-plated silver wire, which is very soft to the touch, and the golden metal parts and the silver-white wire are quite good. In terms of design, qdc 1LE can be said to reflect the value of its limited edition everywhere. The golden main color also highlights its distinguished status. As a limited edition product of the first anniversary, qdc 1LE brings to users It's completely different from other qdc models. At least when you pick up the heavy copper box, you may feel the uniqueness of this product. However, this sense of hearing is the case after 1LE is equipped with a double-segment. If you change to the original silicone sleeve, the listening performance will be different. At this time, the low-frequency sense of 1LE goes up, and the texture is still normal. "It is not, but the overall boring, thick voice, gives a feeling of not quite transparent. In fact, this kind of difference in sound, it is easy to understand, the original double-sleeve size is small, it will leak sound, the low frequency is naturally worse, the silicone sleeve leaks less, the sound thickness will go up, so match The silicone sleeve is the true sound performance of 1LE, and the subsequent listening feeling is also based on the use of silicone sleeve. With the front-end side, I got two players, one is the AK300 that I often use, and the other one is the one that I want to talk about especially, the LP5 LTD199. Let's talk about the listening performance under the AK300. AK's machines all have one thing in common, that is, they don't always pursue big thrusts, the sounds are stable, and the stimuli are rarely seen under AK machines, as is the case with AK300 + 1LE. This set of listening sense is actually just like I described above, not transparent enough, the sound is boring, the low-frequency performance in the single-unit earplugs can not be said to be excellent, but it is still of medium level, the overall sound style tends to It’s popular, it’s full of flavor, and listening to Maroon 5 is no problem. 1LE's performance under LP5 LTD199 is a bit interesting, which is why I especially want to talk about it. Take the same song as an example. The 1LE under LP5 LTD199 has improved overall quality under AK300. The low-frequency texture is from the original one. The enthusiasm to the back is tight, the sound permeability is also slightly improved. Some of these changes make me doubt whether it is the 1LE that I heard before. Considering that the driving force of LP5 LTD199 is greater than AK300, it seems that "the miracle is vigorous." "This sentence is still true. After giving a certain thrust to 1LE, there is a feeling of breaking through the clouds. The follow-up of this player will also bring you detailed experience articles. As mentioned above, the 1LE performance of the thrust to the foot is still the upper-middle level in the single unit, but from the data point of view, qdc 1LE is not difficult to push, even if you use your mobile phone to push the problem is not big, but think There is a better quality to get the player. In other words, the first anniversary of the launch of a unit of earplugs, then qdc 2nd anniversary, 3rd anniversary will not introduce dual-unit or three-unit limited-size earplugs? Looking at the official website of the "limited edition qdc headset" column, I think the possibility is still quite large.
