Of course, these are cheap chinese capsules, because if you have seen the price of the mics I am selling after my changing the capsules and sometimes other parts, these could not have been expensive ones. But I also have tested the expensive ones, and as one can hear it in the audio results I show, even if there are differences, the quality is good. My idea is to be able to make a cheap chinese mic sound much better. The problem I am trying to solve is the following, in fact : I am a professional voice talent and dubbing and voice over teacher. nearly all of the people that contact me and all of my pupils are trying to work in this field and they follow stupid advice from people who lie to sell or form people who don't want them to have their opportunity to work and then by efficient competitors. one of the worst example I have seen is that one : one of my female colleagues (I precise female, because mic techniques , recording methods and knowledge are unhappily not a woman's interest. I don't criticize, I just could acknowledge it. And when women get to be interested in that field, they have to fight to stand equal to men, and finally, they often get better than men) had a tlm103, she was a real pro, had been working for years for tv, radio, etc... but I found her samples poor in sound, and definitely not at the level of a tlm103, which I had owned too. she was also complaining about it and asked me for an advice. she told me a professsional voice talent and sound ingeneer had installed her set. I asked a photo of her home studio. the tlm103 was pointing at the window... opposite to her. She just had to return it that was perfect. What I want to say with this short story is that most people who use or want to use mics professionally are easy to swindle and I found it particularly sad, because most of the time, they don't realise they have been trapped and they relay it to newcomers. Another example : a pro voice talent was advising newcomers to buy an at 2020 to work as a pro. But this mic is not at all used by any professional, real recording studio. And the point is that if you start in the field, and say you are a pro and your mic is that, nobody will take this seriously, and worse, you will considered as someone who doesn't know what he is talking about, even, who can be a liar, saying he is a pro. then, you will find no job with the real clients, and the clients you'll find will only accept to work with you if your fare is ridiculous low. and the clients who don't pay will search for people like you and you will never be paid. so, I find this awful. you know, when you are looking for a mic and you go to ebay, you will see many that say "pro", at 30 euros or less. Pros never use that. then, if people or my pupils don't have the money to buy for instance an at4033, which is the mi I started with, and which is recognized by a good deal of real pros, my idea is to propose a modded chinese mic for a low price, out of which my point is not to make a maximum profit, but to give a possibility to have a pro sounding mic for 100 or 150 euros. so, the capsules I found sound very good for a pro job ( I have very good ears), they are around 35 euros. I don't find a valuable 130 more euros difference in non chinese capsule. For the time being, I am looking for a both sided 47 type caspule that would sound this good, and I didn't find them yet. I am discovering this forum with great pleasure and I think I will find answers to this.
