Game Boy Advance Wire-Free Dehum Dehiss Kit - RetroSix

The physical design of this thing is amazing. I love how it just fits on the PCB unobtrusively without any modifications. However, I'm not sure it did anything when I paired it with the CleanAmp Pro v1.0. Maybe the popping has lessened (placebo? not sure), but the hissing is still there.

After building out my GBA mod i found that my audio just went to absolute ****. I have an IPS screen, Light kit and audio amp installed. The humm and buzzing, especially when i used an ezflash omega cart, was unbearable. First I recapped my board with new capacitors, very small improvement. Next I added a Helder power cleaner mod and it basically did nothing for my audio. Finally I added this de-hum kit and at least 90% of my noise went away. There is still an extremely small amount of hiss when audio isn't playing, but its very bearable. I think these kits are a must if you add aftermarket mods like IPS screen/lights/amps/flash carts/etc. I'll be including one on every single GBA mod from here on out.

Wow this mod is great added the audio amp but had a little cracking and pops. Added this little mod and Bam clean and clear. Also am a soddening Noob when it comes to soddering thought I was going to break the thing cause of that tiny capacitor but no it turned out all right thanks for your time.

Installed correctly but the hiss and hum is still there.

The only humming I hear now is when I meditate.

Incredibly poor product, contacts melted off at less than 190c , RetroSix appears to be the manufacturer so I am not surprised a shame. Alongside further inspection shows that this doesn’t appear to actually Do anything suggesting some things might be Placebo.
