Ground Loop Noise Isolator | Noise Filter for Car Audio/Home Stereo System, 1 pack

I had to export audio from pc via 3.5mm audio jack. Interference was awful, tried high quality shielded cable, still bad. Read up on Ground Loop isolator. Bought this branded device, No Interference at all now, recording is crystal clear. Highly recommended.

I have 4 monitors and sometimes use one of them as a TV. It doesn't have speakers though, but it does have an audio output which I connected to a line-in socket on my PC. Unfortunately that resulted in the dreaded Ground Loop Noise. This thing fixed the problem straightaway. As it happens it's also easy to install and costs only 11 quid. Highly recommended.

Long story short I ordered this to hopefully isolate the ground buzzing from the my psvita to my pc. The interference before this isolator was unbearable and loud to a ridiculous degree. With this isolator it’s still there but noticeably quieter, as if someone cut of about 60-70% of it.

At first I was very sceptical about purchasing this, but I needed to buy it as my PC had a static sound coming through (I have my Xbox/PS5 audio connected through the Noise Isolator) and it got rid of it altogether! Very easy to use, the size of it is very ideal as it does not get in the way. Definitely value for money and the quality of it is superb!

The quality feels good and is in a small form factor , it works brilliantly for removing the Ground loop and EMI noise between my pc and Mixer , however the reason for dropping 2 stars is because of the audio quality , especially the Bass which distorts heavily between 20-70hz and it also starts to soft clip my mixer channels , this ONLY happens if I have my windows volume above 70% but I’m fussy and like to have windows volume high to begin with. So , if you are looking for a ground loop isolator for a car stereo/home theatre or anything that isn’t line level signal , it would be great BUT for PA equipment I unfortunately cannot recommend it , but it does remove the ground loop , hisses , Hum , Digital Hash noises , so as an emergency fix at a gig/venue it will do just fine. Overall: Fixes ground loops and EMI - 10/10 Effects sound quality - 4.5/10 Quality feel - 8/10 Size convenience - 9/10 Value for money - 9.5/10 Easy to use - 10/10

This actually made my worse! I have a pair of Bose Companion speakers plugged into my PC, and when the PC is off, my speakers buzz / hum. I assumed this was ground loop noise, but when I put this device in-between my pc and speakers, the noise got worse and louder.

I was honestly surprised by this little thingy. I was having noise issues between my keyboard and kaoss pad. This little Smof filter was cheap so I went for it. It entirely removed the buzzing, even at high volume. This works way better than it has any right to at the price. It honestly couldn't work any better. It completely got rid of all the noise I was getting. I'm not claiming it will work for any situation, but it works perfect for my setup (keyboard, kaossilator, kaoss pad and speakers all on the same plug extension)

We do not have bluetooth on our car radios and when we go on long journeys we have to charge the phone we are using as a Sat-Nav while we are travelling, we us the AUX port on the radio to listen to the instructions witch is fine all the time you are not charging the phone as well, because as soon as you do we get lots of hissing, cracking & humming which is caused because the radio & the Phone are being charged by the the same source. using this Amazing Little Gadget stops all that noise but does not seem to cut out the volume at all which is brilliant I can even listen to my music and the Sat-Nav at the same time now Very pleased with our purchase.

ラパン２２の純正スピーカーと純正CDオーディオの裏から出したAUXで、DACコネクタを介してグーグルピクセルのＵＳＢ-Ｃから曲を聞いていました。 ラジオっぽい音だったので、5V駆動で3.5ｍｍの入出力が付いたのヘッドフォンアンプを入れました。 ラジオ感も減衰し、音の輪郭と圧も出て、良くはなったのですがどうも高音のシンバルなどのシャリシャリ感が否めず、ＥＱでトレブルをマイナスにして対処していました。 ですが、こちらの商品をヘッドフォンアンプとＣＤオーディオ間のＡＵＸに挟んだところ、全体的に音の分離がハッキリし、高音部のシャリシャリ感だとおもっていたものはノイズだったことが分かりました。それどころか全体的に霧の様にノイズがのっていたのでしょう。その霧が全体的に晴れて、スッキリクリアになりました。 おかげでＥＱのトレブルも下げ、マスターした時の音源に近い状態で聞けるようになりました。良い商品だと思います。

This product works perfectly! I use it to isolate noise when using my PC Line In or AUX IN in my car. I have bought three because they continue to serve me well.

Perfecto, funciona sin problemas.

Funktioniert wie beschrieben. Ich hatte teilweise ein niederfrequentes Brummen und Rauschen in den Lautsprechern die an einen kleinen Htpc im Wohnzimmer angeschlossen sind. Der Grund dafür sind Elektromagnetische Störungen die vom Pc bzw. dem Netzteil über die Erdung Rückübertragen werden. Genau dem wirkt der Entsörfilter entgegen und das zu 100% in meinem Fall. Keine Störgeräusche und Rauschen mehr ohne negative Auswirkungen auf das Ausgangssignal.

Problema solucionado ✅️, tenía el típico zumbido en los altavoces, el sistema era un radio y un míni amplificador de 2+1,la verdad que no confiaba mucho en el filtro pero me sorprendió mucho, ahora el sonido está muy bueno y limpio de parásitos, genial recomiendo mucho,quiero añadir también una cosa la calidad del cable rca es muy importante los típicos cables chinos rca te van a dar mucho dolor de cabeza, los mejores son los que vienes con las puntas bañadas en oro y empantallados (bien aislados)
