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.

I don't have 4mm tube in hand. I will stop by homedepot today and see if I can get one..

I will probably add 3mm OD 2mm ID tube than. Thanks for advice. I hope I have place for two holes on the tip of ear phone. Or maybe I can merge two 2mm OD tubing to one 3mm OD tube and have only one hole.

My first wiring and tubing. First time soldering too so it’s not perfect but sounds comes out when I tested them. TWFK has white damper about 5mm apart and CI has red damper about 7mm away from driver nozzle. Getting my second impression done today and will try to build shells tonight.

I will probably do that way. I am not sure which one goes which, but try left one on (-) and right one on (+). Thanks,

I only had phone quality pics but here they are.

Do you guys have any idea which one is positive and which one is negative on this driver? Straight out from westone w3 with TFWK +CI set up

My first set up I will try with my old w3 drivers will be white on the TWFKs and red on the Woofer. May be locate it around 5~7mm away from driver. If it is too bright, I might just locate white damper at the end of the tip.

Is this the tool you are talking about? I am buying one but it will take about a month to get here. Also I thought I should mount damper while tubing for driver something like this. But I guess you can mount them at the end of the tip to for more effect.

I was thinking butting brown on tweeter instead of green. I might just have to try it first and see how they sound before cover them up with faceplate I guess. I am new to whole DIY project, and don't even know how to read frequency graph accurately. I might just give it a try with what I have...

@dhruvmeena96 Is it usally true that higher ohm damper put on woofer side makes more thump and lower ohm damper put on tweeter side gives more bright highs? For GV, a lot of people recommend to use green on tweeter, and red or orange on woofer. (from Here). I am wondering if Brown instead of...
