In 2012, NuForce won the TOP 3 earphones selected by WIRED magazine editors with a NE600 headset, and the two high-end products UE 900 and B&W C5. The reason for WIRED is that its price/performance ratio is amazing, at the price of 30 dollars. You can hardly find NE600 sound quality products, and now the new earplugs OpForce NE750M is also attracting attention. Yes, you are not mistaken, NuForce has joined Optoma in November last year. Can the NuForce NE750M continue the success of the previous NE600 in today's strong earplugs market?
The design of the Optoce NE750M can be described by the "red and black collision". The petite black cavity is dotted with a red audio duct. This contrasting design style is believed to capture the hearts of many appearance associations.
In fact, there is a hole in the small cavity, but the Optoce NE750M uses two technologies to protect its sound quality. One of them is a core technology called "ultra-wideband single", which exists to enhance the headphones. Frequency response range. The frequency response range is as important as a bowl of soup, which determines how wide a sound frequency range can be accommodated by a pair of headphones.
Although the frequency response range is important, you should also understand that the larger the capacity does not mean the more information, that is, the density of the soup is not necessarily uniform. Also at 20Hz. In the frequency response range of 20 kHz, some headphones may experience extremely fast energy attenuation when encountering extremely high frequency or very low frequency. Although the sound of a certain frequency can still be heard, the sense of hearing has been overwhelmed by the information of other frequency bands. The ultra-wideband single technology can ensure that the sound of the headphones is in the extremely high frequency or very low frequency range, and the energy will not be drastically attenuated. The "whole bowl of soup" is rich in flavor and naturally better.
The second secret of the Optoce NE750M is a cavity shell made of aerospace grade alloy. This material combines both light and durable features with excellent vibration control. We all know that sound is an analog signal. It can cause vibration, which means that there will be some energy loss. The use of aviation grade alloy can reduce the vibration as much as possible. In addition, it is designed with the original scattered frequency load chamber design to reduce the inner ear pressure and sound delay. 8.6mm The titanium-coated diaphragm can have a loose sound field performance and reduce the weight of the earplug.
Thanks to the material improvement, the Optoce NE750M can be lightly loaded with 14g weight while maintaining its own strength. Not only is it comfortable to wear, but it can also fit the ear canal with a variety of earrings. It will slide down easily. The single-button remote control is placed on the left-channel headphone cable, supporting multiple operating systems such as iOS and Android. Adapting to a variety of different smart phones is also a big trend of HiFi headphones today.
How to correctly evaluate the sound quality of a pair of headphones? There is a certain methodology. The choice of songs cannot be arbitrary. First of all, you must choose a variety of music styles. Different styles have different characteristics. In terms of vocals and instrumental music, There will be different sideways. The choice of the front end should also cover the low to the high end, driving the earplugs with different thrusts. Thoroughly analyzing the characteristics and limits of the earplugs is a complete test.
So in order to explore the sound of the Optoce NE750M, there are three kinds of music songs, which are Chinese pop music Faye Wong's "矜" for testing vocals and bass, European and American rock music Arcade Fire's "Sprawl" II (Mountains beyond mountains) is used to test high frequency and instrumental music. The second movement of Symphony Dvorak's "E minor ninth symphony (from New World)" tests the performance of the image and sound field, audio format Unification for lossless WAV.
The equipment selected Fiio X5, Sony A15 player and iPhone 6, Sony Xperia Z3, etc. as the test front end, directly push the Optotype NuForce NE750M. Here also pulled the Auralic Gemini 2000 DAC worth more than 10,000 yuan to drive the Otto The code NuForce NE750M has an output power of 2000mW. Since the Auralic Gemini 2000 uses a 6.3mm audio interface, it needs to be equipped with an adapter for the earbuds. In addition, the Optoce NE750M has been used for more than 100 hours.
In Chinese pop music, Faye Wong's "Holding" is very high in recording, and the singer's mouth shape and sound details are captured very well. Under the interpretation of the Optoce NE750M, Faye Wong's voice is soft and soft. There is a bit of delicate charm. The drums are strong and powerful, the low frequency is slowly spread like honey, and the mellowness is long. This kind of low frequency will not be too much or dull, just like the place where the emotion of the song is embellished. Very full, although the high frequency band is not sharp, but the sound is silky, the performance is remarkable. The vocals are not very close to the ears, and the instrumental music is around, it will not be entangled with the human voice. This is related to some ear products at the same price. Different, Optotype NuForce NE750M sound level is more abundant, and the sound field is also relatively open.
Unlike the song Faye Wong's "Shouzhe" on the vocal focus, Arcade Fire's "Sprawl II (Mountains beyond mountains)" is an indie rock song with instrumental music. At this time, the Optol NE750M is slightly released. The fists and the rhythm of the rhythm are quite satisfactory. It should be like the Optol NuForce NE750M, which is a mid-end plug of around 699 yuan. Most of them will focus on emotional rendering and take a warm and pleasant listening route. But the Optoma The NuForce NE750M is the opposite. Its high frequency will be brighter and clearer, so that instrumental music such as string and percussion can have a fresh taste. The popular point is that compared with other earplugs of the same price. Optotype NuForce NE750M can hear more subtle background sounds, and they will not be submerged in other sounds, the station will be more forward. This may be the officially promoted ultra-wideband single technology, some usually not The attention to detail of the sound can be enhanced, and the information becomes full.
We don't expect the plug below 1,000 yuan to have any amazing performance in the interpretation of the symphony, but the symphony is a test of the overall grasp and control of the earphones on instrumental music. Here as the test track Dvorak "E minor ninth symphony (from New World), selected in 1960 at the Dvorak Hall in Prague, Czech Republic, under the command of the Czech conductor Karel Achel, played by the Czech Philharmonic Orchestra, the record company Supraphon was released in 2002. Since it is Created by a Czech composer, the local conductor and orchestra from the composer should have a certain demonstration effect. Optovi NuForce NE750M will be the second movement of Dvorak's "E minor ninth symphony (from the New World)" The performance is relatively flat and steady, and there is not much attack on the voice. The rhythm soothing part of the overtone is full of considerable sense of space, and the emotions of the song are quite in place. But after the big scene It will be more messy, and the sound will be inconsistent. This is acceptable. After all, the headphones that can make the symphony deductively are more than a thousand yuan.
After receiving the Auralic Gemini 2000, the Optotype NuForce NE750M is getting a lot of thrust sounds and taking it to the next level. The performance is more abundant in the sound level, and further close to your ears. Most importantly, the dynamic range It has been greatly improved. The sound field will become more open in both vertical and horizontal directions. The sound elements will run through it and be patched. This makes the Optoce NE750M more comfortable in dealing with all kinds of styles. Especially the low frequency is like The passing water overflows the sound field and makes the sound long and durable. At the same time, the high frequency is not affected. The earplug sound is not lost due to the increase of the thrust, showing the analysis and imaging force far beyond the same price. .
So our suggestion is, don't regret the equipment in your hand, don't just because the Optoce NE750M is just a plug, just use a normal player to deal with it, which will bury its considerable quality. Optol NuForce The NE750M is a very clean plug. The tri-band has an extremely balanced performance. Compared with the mid-high frequency, it will focus on the performance of the low-mid frequency, the bass is strong and powerful, the vocals are mellow and pleasant, and the high-frequency performance is clear and translucent. In addition, it is also very good in the performance of instrumental music, which is reflected in the rich and bright string and percussion, as well as the wide sound field. Therefore, it is very suitable for rock music, folk songs and villages that focus on instrumental music analysis. .
The 699 yuan Optotype NuForce NE750M is a "maverick" plug. On the analysis, the Optoce NE750M has a deep control of sound, and is stable in the face of mobile phones, music players and even high-end DACs. Sound performance, rich in layers, full of imagery. The most important dynamic range is very wide, with far more than the performance of ordinary earplugs, the sound can be up and down, freely retractable. On the tuning, its own style will be more partial The low-frequency force is thick and very clear. Unexpectedly, the Optoce NE750M also has excellent performance on instrumental music, which is also the most impressive place. It is the brightest color in the middle earplugs. It has a fresh and refined style. The low frequency is full, the vocals are elegant, and the dynamic range is wide. It is the best description of its sound.
