Excellent Ground Loop isolator.
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.

Got rid of my static noise on PC
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!

It works (sort of)
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.

Brilliant Piece of Kit
Brilliant piece of kit.I had a terrible whistle while feeding sound from a video on OBS throught the phono out into an external USB card and onto a second machine running a radio playout system i.e. broadcasting video sound on radio.Soon as I put the Smof between the laptop and the USB external sound card - bingo no more whistle!This had bugged me for weeks.

Does what it’s supposed to , but does effect Bass mainly.
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 - 10/10Effects sound quality - 4.5/10Quality feel - 8/10Size convenience - 9/10Value for money - 9.5/10Easy to use - 10/10

Works but with a cost to sound
Got this to use in my car, having an older cat I bought a cheap android system to sit on the dash and plug in via the Aux socket, soon noticed a whine from the speakers from the a alternator. So I bought this and hey presto it worked no whine, but whilst eliminating the whine it also capped the bass so all the heavy sounds make it Seem like your speakers have blown. It will be returned and I will try to find a better item.

Amazing Little Gadget
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.

NO BS!! This worked for me 100%
Oiiii! I'm sceptical by nature. I read reviews but never fully believe them.I had to write this one because i am honestly blown away how good this lil thing is!!Had a loud hissing sound from one of my Rocket powered speakers when connected to my TV. I thought it was the quality of the cables i used. I bought x2 different RCA cables, tried XLR to RCA. Blamed my Tv. Came across this, and thought i don't mind wasting £8 for another nonsense thing that won't work.I put this thing in and SILENCE!! I was very very surprised. A very happy man!!

⭐️⭐️⭐️⭐️⭐️Zauberrei 😊 Funktioniert bestens, kaum zu glauben! War ein heißer Tipp von Gemini für mein Funk-Setup vor dem Audio-Kompressor, der zog das Chip-Säuseln in den Sprechpausen hoch, jetzt habe ich AST-REINES AUDIO!

ラパン２２に車載したアンプ用で成功
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。

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)
