Finely crafted to subvert the traditional Logitech UE900 in-ear flagship trial

According to the principle of the change of the earphones, the common ones can be divided into dynamic coil headphones, moving iron headphones and electrostatic headphones. In general, the large headphones we see and the vast majority of earphones are dynamic-type products. Due to mature technology and low cost, they are widely used in various grades of earphone products. Due to the high threshold, high price and difficult maintenance of the electrostatic earphone technology, the electrostatic earphone is rare. This is represented by the Sennheiser Orpheus earphone system.

Moving iron type, also called balanced armature type, this type of unit is widely used in in-ear earphones because of its fast response speed and small size. Moreover, due to the narrow frequency range of the moving iron unit, it is necessary to rely on the number of units to widen the frequency response range, and there are technical barriers in the manufacture of the moving iron unit itself. Therefore, the moving iron earplugs represent the high-end to a certain extent, and the price is correspondingly expensive. Quite a lot.

In the traditional sense, Weston, Etymite, Shure, and UE are the traditional four major moving iron earphone manufacturers. They have deep technical accumulation and dynamic product experience, so the fourth is rich. The moving iron earplug products launched by the big brands are receiving much attention. Among the four major manufacturers, apart from custom in-ear earphones, Weston was the first to introduce four-unit non-customized in-ear moving iron earplugs, while UE followed.

â— Logitech UE900 earplugs work fine

Logitech UE900 in-ear earphones work quite well, as can be seen from the outer packaging of the product. If TF15 is the first product after Logitech acquired UE, then I would rather believe that it was completed before the acquisition, because it looks the same as wearing TF10. To put it bluntly, it is the ruggedness of the American products; it is more straightforward, and indeed it is somewhat sorry for the audience.

The wearing comfort is greatly improved.

The Logitech UE900 in-ear earphone cable is very soft, which is another great improvement in terms of workmanship and comfort. In the winter of the day before, the wires of the UM series of the Weston are always hardened, and the TF10 is hard like a steel wire. Now, the Logitech UE900 in-ear earphones are also designed with a twisted pair weave that is soft and does not harden.

This has something to do with the excellent design of the Logitech UE900 in-ear earphones: the units are all back, and the earmuffs are connected to the ear canal through the catheter to avoid the discomfort caused by the cavity of the TF10 deep into the ear canal.

â— Logitech UE900 earphones subjective listening

Unlike the cold sounds of TF10 and TF15, the Logitech UE900 in-ear earphones are warm, and the overall listening feel is not like the one-on-one feeling of moving iron earplugs. Comfort is naturally a deep impression. As a top-level four-unit moving iron earplug, the Logitech UE900 in-ear earphone no longer tests a certain one to impress the listener. The overall balance and momentum is the primary condition for judging it.

The overall sound of the Logitech UE900 in-ear earphone is very full, and there are no obvious short plates in the high, medium and low triple frequencies, which improves the shortcomings of the TF10 intermediate frequency recess. In the low frequency part, the Logitech UE900 in-ear earphones are just right, the elasticity and texture are very good, the low-frequency response is faster, and there is no feeling of muddy water. Personally, the low-frequency performance is the best among the tri-bands.

â— Talk about the trend of multi-unit moving iron earplugs

The Logitech UE900 in-ear earphones are a four-unit design with a total of eight units. This is the second four-unit product after the Weston W4. Although Sony has also followed the four-unit moving iron product, it is not a traditional strength. . Another news came out that Shure will also launch its own four-unit moving iron earplugs. This is just a non-custom earbud, and there are products with up to 8 units and a total of 16 units in the customization.

Logitech UE900 in-ear earphones carrying case

Why do manufacturers want to launch multi-unit moving iron earplugs? This also starts with the characteristics of the moving iron unit. Although the moving iron unit has a fast response speed, the frequency response range is relatively narrow and was originally used in hearing aid products. If it is divided according to the technological age, it is a technology that has been eliminated. In order to compensate for the lack of frequency range of the moving iron unit, the manufacturer increases the frequency response range by means of multiple units. The common two-unit and three-unit are generally composed of a high-pitched moving iron unit + a low-speed moving iron unit or a high-pitched moving iron unit + a bass composite unit.

In fact, the three-unit product can fully meet the needs of ordinary users, such as UETF10 and Shure SE535 with better completion, and many more units are just the unit. I don't deny that the increase in the number of units will improve the sound quality, but this kind of improvement is not obviously obvious.

Logitech UE900 In-Ear Earphones

Personally think that the number of units is not the only way to solve this problem, good tuning methods and catheter adjustment are more effective means, just like the ER4 series single unit moving iron earplugs, the high degree of completion The tongue has not changed significantly for decades.

Logitech UE900 In-Ear Earphones

For the number of units of moving iron earplugs, we have to take a rational attitude: enough. Don't blindly pursue, manufacturers should also guide correctly, and it is not necessary to use the number of units as a kind of trick.
