Yeah, battery might be an issue. It certainly drains battery more than dongle but not like 25% in an hour. I can still listen to music and play some game over an hour with 15% batter life left.

How old is yout iPhone? I see dfr uses more battery than dongle but it shouldn’t be extreme.

I understand now. So if I want more bass from my w3 driver (TWFK+CI) and decided to add one more CI to my configuration, can I just connect them parallen and give proper damper?

I used this product, straight out from box but upright position with no mirror on the bottom. I will try couple more times and hopefully it gets better. I am not expert on any of electrical engineering, so I am not getting this 100%, but I might want to try add driver to my GV later if I want...

Thanks! I used your recipe to make negative impression, but eyeballed 1oz of glycerin not measuring exact amount. First negative impression was not firm enough it cut to pieces when I try to pull it out from container, so I heated left over and put more glycerin, and got that one on the picture...

It is little embarrassing, but here is picture of my okay shell. It turned opaque white after cleaning with 99% Isopropyl alcohol and sanding. It was transparent before that. There is huge bubbles inside, uneven shell width, and quite shallow to fit driver and MMCX adaptor in perfect position...

Great community!!!! So I wasn't giving enough UV to the bottom of the mold. I screwed up first mold by not covering up the top(gave me solid piece), second with whole showing in pictures and third one I cured longer time same position and got thicker outer wall, but still thin U shape but no...

Thanks. I should try that. Here is picture of my first shell which has huge hole in the middle. I think I wasn’t curing it long enough. Or my negative impression has uneven spacing between side wall and where resin is.

I guess I will try that later when I get used to making shell and have one perfect sounding ciem with dampers. I saw one of your picture with crazy configuration. I was surprised that everything fits in to your shell. My shell turned out to be really small and had hard time fitting 3 drivers.

Will red on TWFK kills too much treble? I ordered couple of GV and GK and was thinking about putting green on TWFK and RED or ORANGE on HODVTEC. Is adding one more bass driver a whole different story than just adding damper?

Thanks for the tip. I will try to make them angled later. I have oem westone w3 driver. I temporary pushed iems to my ear with fingers to have air tight fit, still lacks little bass to my taste. I think they have two TWFKs + CI22955. I used WHITE damper for TWFK 5mm apart and RED damper on CI...

Just finished my first iem, didn't turned out correct. First MMCX adaptor is installed too close to ear so I cannot fit them perfect in my ear. However, I was able to get decent sound when I push them towards my ear. I am trying to rebuild them since it wouldn't work. Is there any way I can...

Thanks for info. I will try them.

Made my negative impression yesterday, but didn't work well. I diy'ed my container, but had rough surface on the bottom so it flooded out to bowl. It firmed perfect after putting it in fridge, but when I take it out from bowl, everything ripped a part. I guess I needed little more glycerin to...

Ouch... That doesn’t look good I just manage to get my second impression for right ear. He made sure it goes deep this time.
