I think that I am a music enthusiast, but the economic ability is limited, and the listening equipment I have played is limited. The rest is only this picky ear. I think that music fever is burning money, but music appreciation is also very subjective. Things. In the eyes of others, very popular equipment, if you meet your own style of appreciation, you feel very comfortable listening to yourself, then you do not have to pursue thousands of devices.
For a long time, domestic music and fever equipment are not on the table. To be honest, I don’t use much. I feel that the Chinese people’s own things are for everyone to listen to the sound. As for the sound quality, forget it. Congratulations. In recent years, China has also begun to produce some good things. Think about it too, Cangjie knows the etiquette, people are full of warmth and lust, after eating and drinking, always run to a well-off. China has cheap land to spread goods There are also Shenzhou and Xiaolong, and the Chinese people can’t use the goods themselves to abuse themselves.
In this article, I use the two plugs I have on hand, and the extreme space JDBF headphones N60 and N90 contrast, talk about their listening experience. Subjective feelings plus limited level, you are a brick house, and many advices... extreme Space JDBF headset N60 and N90's outer packaging style is basically the same, are almost all black background, plus a simple red embellishment. This red and black bright match, looks awkward and different.
The product introduction text printed on the pure black outer packaging of JDBF headphones is white and gray fonts. There are two kinds of English and Chinese, mainly introducing the respective packaging contents and product specifications of N60 and N90.
From the outside of the box you can see the look of the N60 and N90. In the big red box, the silver-gray headphones are really revealing, giving people an unparalleled temptation, and a deep shock from the heart.
From the outside, you can see this black small box. There is an English LOGO with extreme space printed on it. What kind of stuff is there? Open it and find four kinds of soundproof rubber sleeves, which are suitable for different users.
Open the plastic film box cover on the outer packaging, pull out a red plastic base, and finally see the N60 and N90 full nude body. The N60 and N90 headphones are very unique in shape, pure black and silver gray match, giving a delicate and compact The metal texture. The English LOGO and model type of JDBF printed on the earphone cavity and the plug are very upscale. Look, is it that the shape is very handsome?
There is also a plastic clip that secures the headphone cable and a very compact product warranty card.
Both the N60 and N90 are 3.5mm gold-plated plugs, which are very pluggable and easy to transmit audio signals. The visual and feel 3.5mm plugs, the connection at the Y-type interface and the material of the earphone cavity should be made of metal because they knock on each other. When it is hit, it is crisp and has a metallic texture.
According to Lao Huang, the wire used in the N60 and N90 is a transparent woven aluminum foil wire. It is very expensive. I don’t know the name of this line, but from the appearance and feel, this line is very different from other brands. Particularly flexible, especially resistant to pull, not easy to entangle, is indeed a good line.
The high-quality wire is a highlight of the N60 and N90. However, if you connect this cable to the earphone, it is better to use the pluggable type. You can replace it after the wire is damaged, and extend the life of the earphone.
Official specifications: 6mm/9mm moving coil drive unit, sensitivity 98dB, SPL@ 1KHz, impedance 16Ω, frequency response 20Hz-20KHz, line length 120cm, line diameter 2mm/1.8mm, gold-plated 3.5mm stereo plug.
From the product specifications, the sensitivity, impedance, frequency response range, wire length and diameter, and plug specifications of the N60 and N90 are basically the same. The only difference is the drive system. The former is a 6 mm moving coil unit, and the latter is 9 mm moving. Circle unit. According to this prediction, the difference in sound quality between N60 and N90 is mainly in the performance of high and low sounds. Later audition proved my inference.
Extreme space JDBF headset N60 and N90 market positioning is about 160 ~ 200 yuan of the public price, so the same grade of the Sony MDR-EX210B and the iron triangle ATH-CK313M to compare auditions, see how the performance of these two headphones The playback device uses the Sony Z1050N, the playback software uses the Rockbox Chinese community doomsday version, the volume is set to -33dB (the volume value I usually use), the audio is set to the default setting, the differential surround and reverb effects are turned off, etc. These headphones have a rated impedance of 16 ohms, so set the equalizer to open and select the 16 ohm .cfg mode.
In addition, I have collected more than one hundred equalizer settings, which are suitable for all kinds of high, medium and low-end headphones and various styles of music. I don't like friends who set them manually or don't know how to set them up. You can leave your mailbox and send you a balanced game. Settings file and loading method. The Rockbox player is powerful and the setup is too much trouble.
The following is the audition music track information. Because it is inconvenient to use Rockbox to intercept music file information, so use the daily listening to view and take screenshots.
Firstly test the noise reduction effect of the extreme space JDBF headphones N60 and N90. Wear the headphones without playing the sound, and feel the surrounding environment noise is obviously reduced; tighten the headphone cable to stretch the hand, the ear has a loud echo, the stethoscope The effect is very obvious. In the case of playing music, gradually reduce the playback volume until you hear the fixed program sound of the external TV. The following are the test values ​​of the four headphones (the subjective test data is for reference only):
JDBF Headset N60: -54dB
JDBF Headset N90: -56dB
Sony MDR-EX210B: -59dB
Iron triangle ATH-CK313M: -52dB
The test values ​​of the four headphones are very close. The noise reduction effect of the JDBF headphone N60 and N90 is small and the ultra-iron triangle ATH-CK313M (maybe the iron triangle is a bit hard), their sound insulation gap is hardly in the actual listening process. Obviously, but compared with Sony's big name is still a bit of a gap. Considering that Sony headphones and the machine match more effective!
After the earphones arrived, I immediately listened to the voices and voices. For more than a week, I listened to several identical albums. Four headphones were inserted and removed from the player, and I listened to the listening experience repeatedly. Finally, I could even close my eyes. Say what is the sound-receiving headset. Now introduce your own music performance for the JDBF headset N60 and N90 to everyone. Subjective listening experience, said not necessarily in place, I hope friends forgive me.
About the high-pitched performance: The high-pitched performance of the N90 is more general. There is no such bright feeling that pierces the clouds. It feels that the flute's sorghum and tooth sounds are not enough. If you add "high-frequency gain" in the Rockbox player, or in the "SPU mix" The sounder is "dry and dehumidified inside, and the treble is obviously beautiful. The high-pitched performance of the N60 is better. The high-pitched voice has a certain penetrating power. In the high-pitched sound, the Sony MDR-EX210B and the iron triangle ATH-CK313M perform slightly better.
About the performance of the midrange: The midrange performance of the N60 and N90 is basically good, especially for the vocal performance. Listen to the songs of Dedema and Guan Mucun, and the lieutenant of Liu Xing. The sound is soft and quiet. Very moving. Personally feel the N60 and N90's midrange performance is very close, compared with the Sony MDR-EX210B is comparable, and feel the iron triangle ATH-CK313M's midrange performance is slightly thin.
About the bass performance: The bass performance of the N60 and N90 is very good, with strong strength, dive and rebound, especially when listening to dance music, the rhythm is powerful and shocking. Especially the N90, the bass performance is better. Compared with the Sony headphones that are known for their bass, they are not inferior, and they are even better than the ATH-CK313M.
In terms of sound field processing, I feel that the N90 is slightly narrower, and the tone performance that is biased towards the mid-bass makes the whole listening experience slightly tight. However, if you add stereo width in the Rockbox player or increase the size of the room in the reverb, feel the sound The field is obviously much wider. The sound field processing of the N60 is better than that of the N90, and the openness is enhanced. In terms of spatial positioning, the N60 and N90 are relatively accurate, and the restoration of sound is also true.
I look at the JDBF headset N60 and N90. If you want to match the high-end fever audio equipment, JDBF needs more efforts. But compared with the random matching of the general mobile phone or tablet, it is definitely not a grade. N60 and N90 workmanship and sound quality are much better, it is an excellent substitute for random matching, it will definitely give you a surprise to change the machine! Compared with the brand plug of the same price, the N60 and N90 work and sound quality is also very good. It is very worthy of a friend who likes music to start a test. Personally think: bass control can not miss the N90, three-stage equalization choose N60, take more than one hundred yuan to buy such headphones, value!
JDBF headset N60 and N90 market price is 160 ~ 200 yuan, personal feeling is worth the value for money, but at this price there are a large number of domestic and foreign headphones brand, waiting for the N60 and N90 to compete and kill. JDBF headset early in business Brand awareness is not high, in order to open the market to expand sales, in order to let more people know JDBF headphones, it is recommended that Lao Huang appropriately reduce the price, or engage in promotional activities, or cooperate with domestic mobile phone tablet manufacturers.
I took so many headphones and various prizes to do the activities, indicating that Lao Huang is very concerned about the evaluation of the products, and I very much hope to make the products better. I am very fortunate to have the opportunity to try the JDBF headphones N60 and N90. My own real feelings and suggestions are given to JDBF. Not all good words are not bad words. The evaluation is not in place and left to the brick house inside the jar. After all, the personal level is limited, and finally I wish JDBF success.
