Good day to you guys. So this is my first post here on Headfi. I often read the forum, but didn't think that I have something to share until now.
I like Sony EX1000 a lot, but I was frustrated with how to wear it on. Especially when I go out on the road. My journey brought me to visit Itsfit, Vietnam on itsfitlab.com. I spent some months with the engineers there and tried a lot of things with the EX1000.
I feel really thankful for their hospitality so I want to share some of my experiments with them. These are experiments with filterless EX1000, which I prefer. (The reason they put the filter there, I guess, is to emphasize on female voice from Japanese anime. But I like the filterless option. The filter is easy to put back on nevertheless). So my experiments with Itsfit including:
- Custom tip for EX1000. This one I didn't like because it doesn't solve the wearing problem.
- Custom EX1000 1 without changing anything: put the whole thing inside a shell, change from sony connector to 2 pin by connecting exk connector to 2 pin connector. After experimenting with this one, I bought some EX1000 to put on the real experiments afterward. Nonetheless, you can choose this option if you want a safe option.
- Custom EX1000 2, cut out the nozzle and change it to a bending one, made of resin. The result is a shift in peaks at high frequency to the right. Almost nothing is changed in bass and mid. Remember the image below is the measurement on their rig (I do compare it with Crin's measurement data and they are not the same). I didn't keep the original measurement but it follows the same line for bass and mid. Almost identical except for the peaks. For my custom EX1000, the shift in peak reduces grains that you might get from EX1000 at some points. This happen to me especially when a female is finishing an opera song, at the most intense moment. And you know, they guided me and let me do the whole thing, from creating the shells, putting ex1000 inside, making the resin nozzle and polishing the faceplate. Best service ever!
- Custom EX1000 3, this time their head designer did it. He carefully re-vented the thing with resin, giving it a little more bass, especially sub-bass. The venting part of the original shell of EX1000 is remove-able and the core is not affected. He also did the beautiful Koi fish design for me. For me, he IS a legendary resheller and custome IEM designer. I was there when he made the breakthrough for this design. A very creative mind!
All in all, I get an unforgettable experience at Itsfit Lab. Their engineer also made a special cable for me, made of copper, silver-plated copper and gold-plated copper, x16. Very special one, nice looking and sound excellent. I must admit that this is the first time I hear a clearly change in sound quality by changing cable.
So that's my story. I'm just feeling so thankful that I want to post something about how they help me get the best custom IEMs I ever had.
