DIY IEM/Headphone Cables
Mar 25, 2024 at 1:05 AM Post #106 of 113
Is there any recommendations on a diy option for iem ear hooks? I have a cable that is already made, but I am missing the ear hooks. Any help would be awesome. I got some rubber sleeves that could slide on but they do not stay on. I thought about burning the opening to seal it up.
Just use 5mm inner diameter heat shrink tubes.

Sounds good, I will give it a try. Thanks.

Are any of you measuring your cables to ensure that they are left/right balanced?

Yes, but honestly I don't think there's any audible differences as long as it's only a few tenth of ohms off.
A few tenth? Which resistance did you measure? My best cable only has 250mOhm. I’m always trying to match them down to 20mOhm or less.

Yes, I also always try to do the same but I have tried listening to some unmatched resistance cables and I just couldn't hear any imbalance. The variations in the impedance of the drivers/receivers are much greater than that usually. like as much as a few ohms. My best cables have resistance lower than my cheapo multimeter that can measure and it only shows the internal resistance of itself, I bet they measure around 5-10 mohms.

are you using 10 AWG wire or how do you figure the 5-10mOhm resistance for a cable with 1.2m length?

Opps sorry, wrong units, I mean 50-100mohm. Maybe you are better at measuring cables or my multimeters always give me fake readings but here is 5.5m of the wire I used for one of my projects:

This one is around 14-15 AWG.
The internal resistance of the meter is around 0.2 ohm, let's subtract 0.1ohm only to allow rooms for error.
(0.4-0.1)/4 = 75mohm per wire for a 4 wire balanced cable and I am unable to measure it with this meter so it's more likely less than 75 (actually 50) mohm.

And btw, 250mohm doesn't sound very low to me, that's about the resistance of all my litz cables.
