After a simple burn-in(about 50 hours), After finding that the sound from this unit hits the moving coil and the moving coil, it easily surpasses the 90 electrostatic headphone units in our store. It''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s really amazing, haha, it is produced by Kelixin, Nagoya, Japan.(Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t make a fuss, this foundry has production bases in more than ten countries, and the base in Japan is mainly for scientific research and production of high-end products.), not a low-end product like Xingdian, the cover of Xingdian unit has no teardrop shape, and the teardrop shape is a unique cover of Kelixin, with an impedance of 32 ohms.(The data measured by the frequency response meter, the sampling frequency of the multimeter is 1000HZ, so the measured value of the multimeter is about 29.6 ohms, which is not a quality problem, but a problem with your test tool)

Talking about the sound: don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t want the poisonous human voice, the density is so high, I feel that the k3003 is the same density, the resolution is not worse than the 1000-piece moving iron, the bass elasticity is good, it is not suitable for bass control, but most people listen, that bass The amount is enough! ! The sound field is also very broad. It can be said that the sound quality of the flat head plug is basically at this level, and it is too difficult to improve it! ! The following 10,000 words of evaluation and boasting are omitted to solve everyone''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s precious time. After all, time is money and life! !(There is a lot of nonsense in the general evaluation, haha)
Beginners must not buy this unit, it is not just a case to find a good sound, you can buy the finished product shown in the picture below, only 399 yuan, almost only the price of the kit, the manual cost is almost negligible(This shell is all metal and it is dozens of pieces a pair.)
Additional free mmcx wire! ! You can listen right away! !

The picture below is a sample for audition. The actual product was sent to the right steel mesh. In the actual test, the effect of the right steel mesh is better, and the sound is more awesome. Tuning is a matter of knowledge. Turned into a tuner, but I think the sound is already very good(Narcissistic narcissism!)Hahaha. . . . .

Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t worry about the bad effect, if you are not satisfied after 50 hours of cooking, there is no reason to return it within 7 days! Warranty 2 years, cost maintenance within 5 years(To put it bluntly, it is a lifetime, who can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t use an earplug for five years, right? Hahaha)![](https://img.alicdn.com/imgextra/i3/49228956/O1CN01NPxYfu2G1tm5C71Rn_!!49228956.jpg)
Let''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s talk about the speaker, if you don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t buy the finished product in the picture above, mature players can use the pk1 shell to match this unit(This store is 19.9 yuan for a pair of shells, and the quality of shells in other stores is uneven, so it is not recommended to buy)The disadvantage is that the tuning cotton needs to be replaced by yourself(There is no suitable cotton in our store), the density is slightly lower, our store is equipped with cotton with a shell of 19.9 yuan, the density is too high, and the effect of this unit cannot be exerted by putting it in.(Putting it in can only bring out 70% of the effect of this unit!)

At the request of many DIY friends who are starting to burn, I specially made a version with a 3.5 plug without a microphone(The cable with the microphone is easy to break, everyone within the galaxy knows)As shown in the picture below, the material price of the kit is 320+19.9+2.8, which is close to 343 yuan, and it only sells for 345 yuan, which is almost free of manual fees!
The key is tuning, which saves you the trouble of tuning yourself. The sound is 666666 hahaha.

pk units all look the same, so don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t look at the appearance, it''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s a thousand miles away, that''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s the reason!
