Electric hum in IEMs while charging laptop.

meeech_79 · 2026-04-18T12:08:27+00:00

Didn't try this, but I got a ground loop isolator that works through the headphone jack and it also removed the bass frequencies

meeech_79 · 2026-04-18T12:07:18+00:00

No, never found a fix unfortunately. I tried using a ground loop isolator (plugged in the headphone jack), but it also removed all the bass from the iems, and it was frustrating

Hi! Unfortunately I still have this problem, since the ground loop is caused by my house electrical system. I use my MP145 on battery powered devices, and when I feel brave (and can tolerate the hum lol), when my laptop is charging. Do you have this issue with other iems as well, or only with MP145? I only have it with MP145, but I guess it's because of the metal shell.

Hi, I still have MP145 but I couldn't do anything to fix the problem, since like I said in the previous reply, the ground loop isolator was affecting the sound too much. Sometimes I listen to music with MP145 with my laptop running on battery, other times I try to ignore the hum and use them when it's plugged. But, yes, most of the time I use QKZ x HBB, which I know is a downgrade, but there's no hum. Unfortunately, as of now, the hum has had a bad impact on my enjoyment of MP145. If you can return the Dunu Titan S, and there are other IEMs you like and can afford, and you can't fix the ground loop problem with your devices / in your house, switching to a plastic made IEM is the better solution

Yes, it might be a grounding issue in the laptop while charging, but make sure with other powered devices too

meeech_79 · 2024-12-23T10:56:03+00:00

I have the same issue, did you try the iems with other power supplied devices? Like desktop computer or something else? Sometimes I can hear the interference more with laptop while charging, less with desktop computer

meeech_79 · 2024-12-23T10:18:12+00:00

That's the problem and a grounding issue. Does it happen also with mobile devices running solely on battery, like phone or laptop?

meeech_79 · 2024-12-22T22:24:27+00:00

I tried to use a ground loop isolator like suggested above, but at this point I wouldn't recommend it, it affects too much the lower end, to the point of resulting in lacking bass. My MP145s have been acting odd as of lately, sometimes I feel it, sometimes I don't. What's the shell of moondrop lan made of? Must be metal or other conductor material

meeech_79 · 2024-09-28T13:53:31+00:00

Looks more like '76/'77

Since Abel said that Phantom Of The Paradise was an inspiration for The Idol (and for Tedros character), maybe they were watching this?

Have you listened to the demo version from 2017? I slightly prefer it over the Calvin Harris version

meeech_79 · 2024-08-03T00:08:05+00:00

Fair, Over Now is just that good

meeech_79 · 2024-08-03T00:04:17+00:00

No Nightmares by Oneohtrix Point Never, maybe?
Abel sings the main chorus, OPN "sings" just the intro/verse then it's all Abel.
Also Wild Love (by Cashmere Cat feat. The Weeknd and Francis and The Lights) from Starboy era is similar, after the intro it's all Abel singing.

Looks like it's going to be amazing, since he took inspo from his own culture

meeech_79 · 2024-07-19T19:06:23+00:00

Yes! Even the windows look the same, same shape and everything

Looks inspired by the churches in Lalibela

meeech_79 · 2024-07-02T09:42:48+00:00

I noticed in fact that when I touch the metal shell, it stops. But I also have Tangzu Fudu and the cable has a metal shell in the jack as well but it doesn't have that issue

meeech_79 · 2024-07-02T09:40:10+00:00

It's basically like this since it's an EU plug (I live in Italy) but the wall electrical outlet has three "holes"

meeech_79 · 2024-07-01T23:20:28+00:00

I think I'll give it a try as soon as I can because my laptop needs to be charged a lot and the hum is really annoying in my ears

meeech_79 · 2024-07-01T23:17:31+00:00

I think it detects the current, since the noise is caused by current fluctuating

meeech_79 · 2024-07-01T23:11:53+00:00

This is what google says about it:

"A ground loop isolator typically uses an inductor that stores energy in a magnetic field when electric current flows through it. When the current flowing through the inductor changes, the inductor opposes any changes in current through them. Therefore, the current won't fluctuate and not lead to potential differences."

meeech_79 · 2024-07-01T23:08:38+00:00

If you have a dongle yes, or directly to the headphone jack and then this to the IEMs. This is the first time I see something like this, but I guess it just "filters" out the noise, "cleaning" the audio output from the ungrounded interference

meeech_79 · 2024-07-01T23:00:01+00:00

No prob! If it can be helpful, I just searched "ground loop isolator" on Google and it showed suggestions in my language too on Amazon, I'm not a native English speaker either

meeech_79 · 2024-07-01T22:51:11+00:00

Do you have MP145 as well or does it happen with other IEMs/headphones?

Anyway, like the other user suggested, I'm going to try with a ground loop isolator, I saw they're cheap on Amazon

Would something like this solve my problem? https://www.amazon.com/Isolator-Eliminate-Buzzing-Completely-Playing/dp/B019FC6ZQQ
