Every time I share Lao Zhong headphones, my biggest fear is to write the beginning of it.
Itself has the English brand LZ HiFi ADUIO it has to register Lao Zhong as a brand name, itself is also a domestic HIFI circle veteran, the purchase channel in addition to a treasure C store, not even a distribution agent, not to mention often go to the exhibition to show their faces.
If there is a group where the bosses of the domestic HIFI circle are in, it is estimated that Lao Zhong is the one who enters the group without saying a word.
However, Lao Zhong headphones are not workshop-style DIY brands, which can be seen from its previous product styling, because DIY manufacturers can always grasp the most trendy appearance, and Lao Zhong's previous headphones are all "ugly" of their own school.
In addition, Lao Zhong headphones are also inside the wall blossom wall outside the incense, in the North American HIFI forum can also search for the evaluation of his headphones, and his previous market is mainly foreign, in the past two years under the influence of the epidemic forced to test the domestic market.
▲ A moving coil plus three Lou's moving iron, plus three tuning styles of tuning holes and 4 kinds of nozzles for fine-tuning sound and 3D printed resin cavity, priced at 1499 yuan, do you think it is expensive?
▲ This A4PRO is actually the sub-flagship of Lao Zhong, the appearance is as shown in the picture, in fact, it is very good-looking, but the domestic HIFI headphones are now this kind of 3D printing resin male mold, the visual effect is similar, only when put together can you detect the difference in resin grade or workmanship.
▲ Lao Zhong A4Pro back cover close-up, similar to amber, the surface layer is smooth as jade, including the LOGO is also in the inner layer. From the gloss of its resin material is better.
▲However, from the side of the cavity of the metal screw tuning hole workmanship is still flawed, it is best to be careful when using the cross to replace the tuning screw. Also, the official did not explain its design, there are knowledgeable please point out.
▲ Lao Zhong A4Pro cavity inside and the tuning nozzle display, the default is black nozzle at the factory, and there are three kinds of nozzles to replace, but unfortunately the official does not explain the style of each nozzle, in short, you like to toss, three kinds of tuning screws + four kinds of tuning nozzles are enough for you to toss.
▲ Replaceable nozzle and tuning screw display, the official sent a small screw at the same time.
▲ The tuning nozzles are arranged, and the line change must be standard. In addition to the 0.78 double needle change scheme, the wire of the old zhong is 8 strands of graphene copper silver alloy wire, silver gray appears to be relatively plain, although the main line is coarser, but the softness is good, in addition to rubbing the collar when wearing, there will be a stethoscope effect, and other good.
▲ Look at the official purchase page only 3.5 plug, but it does not matter much, this A4PRO is better to push.
▲In terms of parameters, there is very clear information on the box, impedance 26 ohms, sensitivity 112dB, frequency response range of 5Hz-40KHz, channel error and distortion have clear data. In addition to the larger frequency response range, the others are all in the normal range, in fact, looking at these core parameters is not too much information, can only be said to be not difficult to push.
In terms of unit architecture, the low frequency is responsible for a double-cavity carbon nanotube CNT diaphragm dynamic, the intermediate frequency is responsible for two Lou's moving iron units, and the high frequency is responsible for another Lou's moving iron unit. The official purchase page information is relatively simple, not only is there not a sentence that violates the advertising law, but there is not even a tall sound quality description, yes, Lao Zhong headphones are a brand that is unlikely to do promotion.
▲The following sounds are based on black tuning screws and black mixers, which are also the default adjustments at the factory.
Let's talk about easy pushing, personal use Huawei mate30 direct push, although the low frequency is not full and strong, but the sound field scale is large, the elasticity is excellent, plus the sense of volume should not be underestimated, there is a little sense of disegragement.
The overall analysis is still natural, and the brightness of the if-frequency instrumental music can be a little brighter, but the vocals are very natural, although there is a little bit of low frequency, but it is warm and stretched.
There is still significant room for high-frequency brightness and dynamics when the phone is pushed directly, but the instrumental separation and sound field are very good, and the overall transparency and musical taste are out.
Obviously this is a headset that requires a little thrust, if the front end is limited, add a small tail, and the individual has a good push on hand.
▲ Coupled with the thrust after the LINK2 is more than enough, A4PROde low frequency can easily get a strong sense, listening to the "California Hotel" Frozen Hell Edition, the drums in the prelude are like coming from the back of the head, wave after wave, but not head, plus a wide sound field, the sense of presence is touching.
And fortunately on the Beam2, the voice of Lao Zhong A4PRO is still a little low-frequency on the mobile phone, full, bright and stretched, listening to the eight eyes in addition to the obvious purity, there are three points of warmth and stretch, the details of the performance point so far but very natural, the voices of different members can be easily distinguished.
Female vocals listened to Cai Qin, Li Xinjie, Sun Yanzi, Karen Mok and Faye Wong, more thrust than male vocals, the analysis is not perfect enough, but the thickness is suitable and the thickness of the stretch, listening to Cai Qin in addition to the analysis of the lack of heat, other are very good, is the best interpretation of these female voices. Followed by Sun Yanzi and Li Xinjie, personally increased the volume, the thickness and stretch are very natural, there is a slight magnetism when listening to Sun Yanzi, the tooth tone control is still natural, but it is not clear enough; Li Xinjie's sweet feeling is no problem, but the tooth tone is not natural enough, the breath is too heavy; finally, Faye Wong and Mo Wenwei, the volume is not natural to open the analysis, the volume is not analyzed, and the volume is not analyzed.
Due to the sufficient thrust on the BEAM2, the high frequency of the Laozhong A4PRO immediately presents a full and bright high frequency, the sense of extension and dynamic are remarkable, coupled with the open sound field, the overall sense of transparency and musicality is also very good. The disadvantage is that although the instrumental performance has a more obvious analysis, it is not particularly delicate, and it can only be said that the timbre tends to be neutral, and in the small orchestral music, its strings and wind instruments are taken into account, rather than the kind of strong analysis when only the strings are prominent.
▲ Finally, talk about the performance on the player, personally used Qianlongsheng QA361 and Lepi L4 respectively, the thrust can push the A4PRO, the value is not enough for the latter or more suitable for some low-impedance high-frequency headphones.
Listening to some of the explosive metal percussion on QA361 will be a little noisy, not a sense of headbanging, but the old A4PRO itself has a strong sense of volume at low frequency, and the sense of transparency is not loose enough when the extremely fast drum kit and electric guitar are mixed, of course, if it is tender or like the jazz rock of the Horror Channel and the folk songs of Bob Dylan and Neil Young, it is not a problem.
This is less pronounced on the Lepit L4, which can handle a variety of styles on low frequencies, even electronic rock and ACG styles.
Of course, if you don't listen to rock and roll, it is easy to say, for the national instrumental music of the big drum class, Lao Zhong A4PRO is more than capable, including Ryuichi Sakamoto and Hans Zimmer.
In terms of vocals, the two players have a good performance, the male voice performance is more neutral, not thin and not thick, pure, analytical natural, and with the small tail of the degree of nothing to say, good enough.
The female voice is greatly improved, and it is not at all the same grade as when using the small tail. The thickness is natural, there is no cold and warm trend, the analysis is not sharp, there is no sense of density and mouth shape, but the clarity is natural and soft, the tooth tone is very natural, and the female voice that controls Cai Qin and Sun Yanzi in two completely different styles is handy, and the overall performance is similar to that of the male voice.
High frequency relative to the degree of LINK2 improvement is not obvious, the same is such as the sound field, brightness, instrumental separation and other basic qualities are excellent, the difference is that it is more bland, the overall sense of transparency is not a word, the musical taste is less, but the high-frequency instrumental performance appears to have some talent.
▲Overall summary section
After listening to it intermittently for a week or so, the overall feeling of lao zhong A4PRO to me was that there was no too prominent part, and of course, there was no obvious shortcoming.
Compared with the low-end circle iron of the domestic HIFI mainstream circle, although it is easy to push, the thrust requirements of its old loyal A4PRO when it started are a little larger, at least on Huawei mobile phones.
Fortunately, the small tail is more prevalent now, plus it has no special trade-offs in the sound, in addition to the high frequency did not surprise me, the low and medium frequency performance is good enough, but this does not mean that it is a stopper on the lower plate, and the distribution of the sense of volume is also balanced.
In addition to sound quality and price, the biggest feature of Laozhong A4PRO is its playability, a pair of headphones can get a variety of different senses of hearing, which is worth exploring for burners.
