Anyone from Singapore or Msia? Used to make RAB-P myself. But got really busy with work and had no time to DIY or repair my own RAB-P. Willing to pay for your service to make a RAB-P.- Choy Wei De

You can offer me a house and a car for 20K. But I simply just cannot afford them. I get the very good price for that it offers. I can’t afford spending $50 at this point of time for a solder.- Choy Wei De

I have tested, if my temperature control is still working, at 300C the enamel do burn but need to give it some time. I believe at 350 or even 400 it will achieve the effect faster. Time to get a new solder.- Choy Wei De

I try to minimise the number of tools I need to make a iem. I can’t control the lighter very well anyway. I burned MMCX and some driver using 220V temperature control, but the control spoil. That’s why I changed to USB solder. My USB solder tip is small enough that I can start melting iron...- Choy Wei De

I’ll try to use a more powerful soldering later. I mainly use a 5V USB solder, because it heats up very fast and very easy to set up but I think it might not hot enough to burn the enamel.- Choy Wei De

I have a very basic question. For those who wire Zobel straight to the wires. Sometime I do suspect the way that I’m doing it does it even make the electric connection. All my wires are pre-cut to 3cm long, I don’t want to cut my wire into two. So what I did is to use the solder and try to...- Choy Wei De

I donno why, but Zobel on RAB makes all the difference to me. I can’t listen to RAB without Zobel. I have not tried other drivers with Zobel yet.- Choy Wei De

I have bad experience with this kind of wire downward and plug straight into the ear. I prefer at least at a angle like Xiaomi earbuds. I uses this, quite comfortable and good deal if you manage to find the right eartip.- Choy Wei De

Normal IEM maker will ask you to go for tip rolling, means try ‘every single’ ear tip in the market. I also have slightly picky ear canal, but I manage to find a few shells that suits me. Let me know if you have access to Taobao.- Choy Wei De

@homerograco The way I understand is very unique. A smaller ID tube is like a river with rushing water. The surface of the water is not travelling the same speed as underwater, not cohesive. When a river flow to a bigger tube, ‘pond’ or ‘lake’, the surface of the water slow down and back in...- Choy Wei De

Personally I think the material of the tube matters. But not sure will it be noticeable enough. I think the best way to test is to print a short tube and compare with normal tube, e.g a 15mm of 2.0mm ID tube. Or if you really want, build a simple single driver like RAB/RAF, ED using resin printing.- Choy Wei De
