It turns out that pro, like plus, was born under the impetus of a big boss in order to better drive high-impedance headphones. I listened to the engineering board in June of 5438+00, and I felt that the thrust was great, but I used a relatively simple treatment method: highlighting the line sense of high frequency, strengthening the resolution of each frequency band, improving the sound quality, and also affecting the sense of music. There are more teeth at high frequency, and the listening ability is much lower than that of plus.
These two months have ushered in the retail version of Beam3pro. As a result, the female university changed eighteen times, and the voice was completely unexpected (O).
The packaging of Pro follows the design of plus, using a very textured dark blue carton, with audirect trademark on the front and product parameters on the back. But the first batch of products printed the minimum output power wrong, not 247, but 427. Please collect "Wrong Edition" (O).
Although pro and 2se used the same mold, Mr. Mu made some minor adjustments according to some feedback from plus. The frame is replaced with the same blue paint as plus, which is more beautiful and durable, and it is not easy to scratch.
On the second floor of the box, there are: paper instructions, single crystal copper-plated Type-C cable customized by Taiwan Province Province, copper alloy plug protection seat, gold-plated plug and braided rope cable. Awesome! Due to the cost pressure, plus no longer provides the Apple Line. This time, pro is said to give a customized Apple adapter at random before New Year's Day, which is still made by seiko without any compromise. Cool!
Pro and 2se sockets are the same. When inserted tightly, the wire plug protection seat is flush with the shell, and the connection is very firm. The buttons on the side adjust the gain. The red light is high gain and the green light is low gain. Considering the great thrust of pro, manufacturers remind users to be very careful when pushing iron earplugs, but I don't think Pro is totally unsuitable for pushing iron. I use low gain to push the aurora borealis, which can not only squeeze out more low frequencies, but also keep the fineness of high frequencies. It would be better if it could be thicker (O).
There is only a 3.5mm single mouth at the bottom, which is exactly the same as 2se. Converted, the thrust of the third gear gain is about115mw (16r)150mw (32r)13mw (600r). If the thrust is only 32 Ω, it has surpassed the vast majority of small tail fins on the market, which is the same as the previous Link2 with the largest thrust.

Let's talk about something beside the point first. I have always recommended the small tail of Liang series, because wood is always willing to cut materials in invisible places; Grab where you can't see. Just like this pro, everyone will be relieved when they get the plus sign. Teacher Mu still wants to do better and find a breakthrough direction. I admire that.
Beam3Pro is designed to drive high impedance headphones. There are also some small tail wings with great thrust on the market, but the design principle and internal circuit of pro are completely different from others. It imitates the process of large-scale HiFi system, from decoding to first-stage amplification (equivalent to the power amplifier of large-scale speaker system) to second-stage amplification (equivalent to the rear stage of large-scale speaker system), and finally to the second-stage amplification output with independent left and right channels. Decoding-front stage-rear stage-speaker (earphone), such a design Beam3Pro should be the first one to eat crabs in the market at present. According to Teacher Mu, the retail version has increased the post-amplification compared with the engineering version; POP explosion-proof audio chip; Stack 300 milliohms of internal resistance and capacitance.
Beam3pro Small Tail Company Huawei Mate20Pro(UD), HarmonyOS System 2.0 System, Haibei Music APP, exclusive mode. Auditioning with KPE JZ MOD single-acting earplugs, one ear feels that the gain of pro is very strong, and the sound changes in each gear are very obvious. As far as audition earplugs are concerned, the gain is the most comfortable, and the hardware volume is only 9/32.
The performance of high frequency is completely different from the previous engineering version, but it is very close to 2se. It seems that Mr. Mu finally chose the scheme that has been tested by the market, which is more secure and makes the high-frequency tooth sound processing very good. Under such a great thrust, listening to the unaccompanied female voice "One Love" is still delicate and moist, without stabbing or breaking. The retained small teeth sound increases the texture of the sound, and the ups and downs are very easy. Different from the silky feeling of plus, pro is more real, transparent but not very bright. Listening to the violin will not be so rosin, nor will it be like pulling a tightrope. There is texture, detail, extension, soft edge, and it is not tired after listening for a long time.
I am most satisfied with the same series, Hilidac Beam2SE small tail.
Compared with 2se, the performance of low frequency is greatly improved, the speed is slightly slower, the dive is deeper, the strength is appropriate, and it is fluffy, which sounds a little more sense of quantity and atmosphere. The key is high quality, tenacity, ability to play, bounce, not dragging their feet, rich levels, and not bumping their heads. I was worried that the sound of thrust would become thicker and the low frequency would be turbid. Pro's performance completely dispelled my previous concerns, very good!
Intermediate frequency, the density is not as high as plus, but it is a little warmer. Excellent sound insulation performance and excellent positioning. Listen to the male group singing "The Girl of Osaka Castle", with clear left, middle and right. Maybe it's because the voice is completely turned on and I feel a little bigger than before. The voice is close to the surface, but it is not a big mouth. It's just that sometimes I feel that the sound plane moves to the back of my head, and the depth is very shallow, which is not satisfactory. Fortunately, the dynamic is good, the sound is vivid, and there is no problem of flat sound.
The biggest feeling is "working hard to create a miracle". KPE JZ MOD has been listening to various devices with me, and its sound characteristics are already familiar. I thought the potential was almost the same, but the performance of Pro was beyond my expectation, which was a bit like the feeling that the yogi was pushed to get through the second pulse of Ren Du. The context of the whole voice is much clearer at once, and it is much easier to cope with big scenes at once; For example, HDR is added to the photo, and some hidden tri-band details emerge, which can be better captured. As far as listening is concerned, the biggest feeling for me is that the sound becomes very stretched, and the high frequency wins the sky, and the low frequency dives into the gutter. Both ends are completely extended, and the scale has reached a higher level. Moreover, under such a large thrust, it is very stable, relaxed and happy, taking into account the sense of music and excellent listening ability.
After getting a large thrust, many devices like to increase the energy sense of tripling, which will be more exciting, but it will also be relatively top and easy to make people tired. Fortunately, Pro is not so simple to handle, but it turns these energies into a kind of energy storage, so that the performance of sound is still contained, reducing aggression and ensuring the resistance of hearing. This treatment is very advanced, awesome!
When I switched to the only big earphone in my hand-Philips X3, I had an accident during the audition. After the single-ended jack of Philips random line is completely inserted into Pro, the contact is poor, which leads to the distortion of sound hole. Other devices have not encountered this situation. Yes, I compared LINK2 with the same thrust, and X3 is normal. Both of them need the hardware volume of (Pro high gain) 18/32, and the sound base is also very similar, except that the sound of LINK2 is more straightforward, the low-frequency dive and sense of quantity are slightly inferior, and the vocal charm is not as strong as Pro.
Generally speaking, as an upgrade of Beam2se, as a small tail to deal with big headphones, Beam3pro has achieved its goal very well, and still combines the high-quality workmanship and materials of General Mu, with remarkable sound quality and full firepower. Although Mr. Mu suggested himself: Plug plus wins completely, and the big earphone is given to Pro, I feel that no matter how big or small, there may be a surprise (O) if Pro pushes the earphone in my hand.
In addition, the pre-sale price of 65438+February 1-10 is 799 yuan.
At the end of this paper, Mr. Mu sent another artifact that claims to continuously improve the sound quality. HiFi is endless (. |||| | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
