Sennheiser Amperior is a rare headset that is not named "digital" by Senhai. This English word does not seem to have a direct explanation. Its name is unknown. However, Amperior's positioning is Very clear, the official said that it is positioned in the DJ's monitoring application. And it has a very good "predecessor", Amperior from Sennheiser "old" HD25 headphones, from the appearance of Ampeiror also similar to HD25, and The details of the HD25II sold are basically the same. The official price of Amperior is 2699 yuan, which is about 1000 yuan more than HD25-1 II.
Unfortunately, we have never heard of any generation of headphones from the Sennheiser HD25, so we can't compare them in today's main observations. But the appearance of the Amperior is still very eye-catching, just have a little look at the HD25. History, you can see these "historical" traces on the Amperior headphones. Some netizens commented on the Amperior atlas article that they didn't like the appearance very much. It really has very old earphone design elements on HD25 and Amperior.
Sennheiser said that Amperior is a special version of the HD25, such as low impedance, more suitable for DJ tuning, etc. In terms of appearance, the HD25 has maintained a relatively old design. The Amperior uses a 36mm diameter speaker unit. The enclosed single-unit installation design is a slightly larger "embossed ear" style when worn. It is a bit larger than the Beyerdynamic DT1350, which was recently evaluated.
The headrest of Amperior's headstock and fixed earphones is quite retro. The headstock is very ordinary plastic material. The top cushioning material is the surface of the flannel that Sennheiser likes. The headstock can be separated into two tracks from the middle. "In the old fashioned headphones, this design can be worn by users of different "head type". Adjusting the width between the two rails can improve the wearing comfort and stability. The fixed bracket mounting of the unit is more retro, and the earphone unit housing is directly Inserted by a plastic bracket, the bracket will extend beyond the headphone unit at a minimum size of about 5 cm. It looks really different, but this old-fashioned design is very interesting.
The Amperior headphone cable is also very old-fashioned. The headset uses a single-sided cable connection, but the headphone cable, the plug, and the left and right channel cables are deliberately placed outside. The "flying line" may be a derogatory place in many places. Words, but it is very interesting to combine such a retro design. The red plug is connected to the right channel on the side of the line, and the line connected to the left channel is passed through the head frame of one of the tracks, and "flying out" "If you only look at the picture, you think that this is why DJ application optimization, and this is actually the traces left by the old-fashioned headphones HD25. Such a flying line may be helpless for decades, and it is retained until now. Retro design language.
Amperior's headphone casings are available in blue and silver. The casing seems to be made of aluminum and has a fine grain of oxide on the surface. Although it is custom made for DJ applications, it does not seem to be customized for DJs that are "dish". It doesn't have a particularly tight headstock [adjustable size is really big], and there is no way to hold the mono monitor. From the Sennheiser official spokesperson's promotional video, it seems that Amperior is more biased than the HD25. monitor.
Compared with the HD25-1 II, the Amperior has different parts of the earphone casing and ear pads. The Amperior 18 ohm impedance and 120dB sensitivity are better than the HD25-1 II 70 ohm impedance and 108dB sensitivity. Push. So what is the performance of Amperior? This headset is sent by the user, has been used for some time, we have lost more than 300 hours for the headset.
Since there is no HD25 and other related models, there is no specific comparison object. The test reference headphones are Beyerdynamic DT1350, and also refer to the style of Sennheiser HD580 and HD650. We use the source of the hand as much as possible. Resources, next will talk about the performance of different audio sources. The player part uses FIIO X3K, FIIO X5, Cayin N6, Paw Gold, etc. as a reference, the sound card part uses Monitor 06 MX as a reference, and also uses the HP11 and other headphone amplifiers.
Overall impression : Amperior's sound style is the same as its appearance. It is a somewhat retro-sounding earphone. Although it has a metallic appearance and a relatively popular small ear-like appearance, its sound is modern and modern. The earphones are obviously different. As a closed earphone, it has retro features. Its overall resolution is not the current top or high level, but the overall listening and control is very easy to match the sound source of various grades. Its high frequency is slightly dim, the mid-range and low-frequency parts have very good elasticity, and the overall style is almost invisible to you in closed-end headphones in recent years.
High-frequency performance : In the official propaganda of Sennheiser, it may be emphasized that Amperior is easy to drive, easy to match with mobile phones and other players [with wire with wire control, changeable line design], of course, it can also improve digital sound. The most important thing is to start from the high frequency. Amperior's high frequency is relatively dark, the sound has a good density, and it has obvious warmth, the transient response is relatively slow, and it has a good elastic style. This style is very Like the old-fashioned diaphragm, the response is not fast enough, but the transient details of the delay are very real. With Amperior to listen to the violin, you may not feel the extremely delicate high-frequency extension, but you can feel warm , full of sound, and very appropriate sound tension, and a slightly modified sense of dynamic control.
Unlike most closed-type headphones that emphasize high-frequency fast response, the sharp transients are completely different. Amperior looks calm and has tension, but it does not lose its texture. For guitars with stringed instruments, it also shows calmness, but resolving power. The sense of air is not its long term. It is stable, clean and has no sharp high frequency. It is easy to show the gentle, introverted and tension-free side of most sound sources. It really has some HD580 early works. Traces [it is better than HD580 resolution].
IF performance : Amperior's intermediate frequency is much better than the DT1350's dynamic, thickness and medium-high frequency connection. As a closed-type earphone, such an intermediate frequency is probably second only to the iron triangle M50s. However, as a closed-type earphone, it is not too big. The volume of Amperior's vocal performance is relatively obvious. Of course, this part is greatly influenced by the sound source. The following is specifically mentioned. Under the FIIO X3K, mobile phone, vivo X5 Max and other audio sources, its intermediate frequency is instead Introverted, soft, on some neutral sources such as X3K, more delicate, softer. The mid-high frequency part of the explosive force is not so strong, but more stretch, the sound field space feels better, but the image is normal.
However, with FIIO X5 or better Paw Gold, Cayin N6, Amperior's dynamics will be greatly improved, the IF image is more stereoscopic, but it seems that it is not as soft as before, the sound is slightly harder, but the overall style is still restrained. Mild. Under the N6, Paw Gold and 06 MX, if it is a very good vocal recording, Amperior can show significantly better vocals and IF performance. The sound tension is very good, although not soft and delicate. The style, but it has a very positive image and style. The middle and low-frequency parts are slightly squeezed and modified. The sound will have the so-called "simulated taste" elasticity. This kind of sound is more than the weight of the HD650. Looks stretched.
Under the dynamic music, Amperior has a good potential when it comes to mobile phones, X3K and Vivo X5 Max, but if you have experience, you will hear that it is a "sound source" to feed the headphones. It is powerful but lacks a little. On a better sound source or desktop amp, Amperior can show a solid mid-range. The sound level and shape are clean and full under large dynamics. It has the shape of HD600 and HD580. Just as a closed design, the explosive power is still relatively general. However, on the 06 MX, N6 and FIIO X5 level audio sources, Amperior's IF dynamics have been greatly improved over the entry source.
Low frequency performance : Amperior's low frequency also has a more retro taste, the dive is not very deep, but it has a special "elasticity", this elasticity does not have too much detail, but it increases the dynamics of low frequency It has a very positive effect. It is different from Sony's closed-head headphones with low-frequency hairpin, AKG-enclosed headphones, low-frequency, and dry hair, and the Aurvana series is different from the low frequency. It seems to do some extrusion. , appropriately enhance the dynamics, but also lost some of the deeper details of the dive.
On the sound source of mobile phones, Amperior already has a good low-frequency sense. In the big dynamics, it has already shown a slightly better momentum than the low-frequency of the entry-type headphones. It is only a resolving power. With a better sound source or amp, Amperior low frequency And the dynamics of the intermediate frequency will be significantly improved. The sound of the lower part of the whole intermediate frequency is obviously more balanced. The intermediate frequency and the medium and low frequency are obviously more stereoscopic. With HP11 or better amp, Amperior can show very good explosive power. This kind of resolving power is general, but the flexibility and the low frequency of the atmosphere and control force are displayed on such a small earphone, which is still a little pleasant surprise.
to sum up
From the positioning of Amperior, I hope to use the continuation of the retro look of the HD25 and some popular element design, let it go with the market, DJ or the market with mobile applications. Its DJ style and pioneers and even AKG disc DJ The pursuit of the low frequency is completely different. Amperior is still a sound balance, the sound is somewhat retro, the high frequency is slightly dark, and the dynamic performance is excellent. As a closed earphone, its performance is absolutely remarkable, not pursued. The ultimate resolving power gives it a significantly better adaptability to the sound source, while the momentum and control under the big dynamics, although not the top detail, have a very good sound shape and level. This trend is indeed Some are like HD580 [old models], but they are also very different. Amperior is not difficult to push, but with a better player, obviously it can get significantly better results.
It is worth mentioning that this type of earphone is not superior to the new generation of earphone diaphragm technology, and will be used by many people who are interested in it. For example, when Xiaomi headset is evaluated on a foreign website. The reference object is the Sennheiser HD25, and it is concluded that some aspects of the Xiaomi headset are better [the details of the very high frequency are really better for Xiaomi]. If the performance of the HD25-1 II is 50% of the Amperior, That sounds far better than the millet headphones. The overall performance of Amperior is far better than the Beyerdynamic DT1350.
HDI Pcb
Hdi Pcb Specification
High density interconnect (HDI) PCBs represent one of the fastest-growing segments of the printed circuit board market. Because of its higher circuitry density, the HDI PCB design is able to incorporate finer lines and spaces, smaller vias and capture pads, and higher connection pad densities. A high density PCB features blind and buried vias and often contains microvias that are .006 in diameter or even less.
Key HDI PCB Benefits
The evolution of high density PCB technology has given engineers greater design freedom and flexibility than ever before. Designers now have the ability to place more components on both sides of the raw PCB if desired. In essence, an HDI PCB gives designers more space to work with, while allowing them to place smaller components even closer together. This ultimately results in faster signal transmission along with enhanced signal quality.
HDI PCB is widely used to reduce the weight and overall dimensions of products, as well as enhancing the electrical performance of the device. It's regularly found in mobile phones, touch-screen devices, laptop computers, digital cameras, 4G network communications, also prominently featured in medical devices as well as various electronic aircraft parts and components.
