Recently listened to two earphones, their ears also heard the difference, the feeling is quite impressive, is to write a sense of listening, and the value of friends to share.
I. Baiya Power DT990 PRO
I have a 250 euro version. There are also 32 euro and 600 euro versions of this model. As for the brand, impedance, and so on these, I do not say in detail; I believe that the person who can see this article is certainly not unfamiliar. This earphone should have a large quantity. It is the monitoring series of Baiya Power Earphone, and it is positioned as the early monitoring flagship. Its civil flagship before is DT931, and then there is DT1990 Pro. This series of appearance and artistry are very low-key stuffy Sao, predominantly black color matching. The DT990 Pro has a single, non-replaceable phone cable, an iron headphone beam, a replaceable leather headband, a plastic headphone body, silver-gray velvet earmuff, etc., open, moving loop design (it feels more like a semi-open since the back isn't fully open). The wearing comfort is okay, but because it is used for monitoring work, the earmuffs' pressure is still there, so it can be felt when wearing for a long time to avoid falling off during work. The plug is 3.5 inches to 6.5 inches which is screwed to 3.5 inches.
Second, the Hifiman HE400se
This is a new type of earphone. It's also prevalent these days. This brand even did not say in detail, mix green altar 2000. This earphone is a flat earphone with an impedance of 25 ohms. It is flat-driven and different from diaphragm earphones. The headset is positioned at the tablet headset's entry-level, and there is a gap between the price and the 990 Pro. This is the first time I buy this brand of earphones, and the previous players have left me feeling nervous about the quality control of this brand. Fortunately, I got the earphone and found that the appearance and artistry were worthy of its price. HE400SE is a bilateral replaceable cable design. The earphone body replaceable cable port is a 3.5 plug, and the earphone body line also distinguishes left and right; a replaceable line means that you can play balance. The headset beam should be made of aluminum alloy, and the headband cannot be replaced. The protein leather is also made of this kind of material, but a circle of black suede is attached to the ear's contact surface, which is carefully designed. The headset is a plastic body with an open design and a metal mesh on the headset's back, but the metal mesh can be moved by hand, which surprised me a bit. The headphone plug is a 3.5 "elbow but also has a direct plug 6.5" adapter.
Three, appearance artistry comparison
Compared with the two, HE400SE is larger; aluminum alloy silver with the headphone body plastic light treatment looks more fashionable, 990 PRO black, gray match, more reflective and durable. The artistry is almost the same, both have a little groove, but the price is reasonable. The weight of HE400SE is more solemn than 990 Pro, but the wearing comfort can be refined. Because the earmuff pressure is small, the fitting feeling is not as good as that of 990 Pro, which is a contradiction. The head beam adjustment 400 is smoother than that of 990 Pro.
Four, listening to a simple comparison.
I'll compare it with the most straightforward equipment at hand. Tianyi EF100 headphone amplifier is a class A ear amplifier, output 32 ohm for 2000mW, 300 ohm for 240mW, thrust should be no problem, and the machine's maximum volume is 80, the immediate hit to 40 is enough, the visible margin is still large. It mainly uses its U disk to play local lossless tracks to listen to headphones, direct ear decoding. It has an exciting place, is a 6.5 and 3.5 double output, which is suitable for A/B comparison.
To sum up, when the 990 covers the shell with his hand, the sound does not change. When the 400 covers the body, the sound changes a lot. So the 400 is more open than the 990. The 990 still has the potential to be explored for those who want to play more deeply, for low-frequency repertoire, small classical arrangements, single instruments, especially violins. 400 is friendly, suitable for the initial burning, do not want to put too much, there are requirements for sound, and is more suitable for listening to the human voice, listening to the low drum frequency is a little bit of metal tapping foot, low-frequency elasticity and texture are low.
Finally, I took Huawei's tablet and tried it. I didn't expect that the Huawei M5 tablet thrust can be better than a mobile phone. Although it can't compare with Tianyi's, the Yiduo 05Plus can't compare with Tianyi's, but they have different positioning. The benchtop ear is placed in the aspect of looseness or a few more potent than the portable ear. After listening to the tablet, the conclusion is the same as before, only the 400 voices are close to the ear, and the 990 representatives are relatively far away. The quality of the 990 is higher, and it is not unreasonable to sell expensive land, but the 400 still has its market space in terms of human voice and equipment adaptability.
