3.5mm Audio Noise Filter, Ground Loop Noise Isolator for Home/car/Computer Stereo Systems

The thing works. That's it. Aggravating noise 95% gone, insignificant audio compromise that was easily fixed with EQ. Used it on Dell OptiPlex 5060 desktop PC. Just plug isolator into rear speaker input, then plug yer speaker cable into the isolator. Couldn't be easier. I listen on headphones now with nearly zero noise. Huge difference. Great value! Recommend.

Wasnt expecting a lot of reduction, like 50% but id say 95% of it was eliminated. Using this for iem, plugged into my pc (3.5mm). Good value, good job

This is a complete waste of money. It did cancelled the noise but it drops the volume of the Bluetooth device by almost 50%, there’s no bass in the music, and you can barely hear it at all as well. Not worth your money. DO NOT BUY!

This did not change anything. Still have noise

Funciona perfecto! Tengo unas bocinas desktop junto a mi laptop y al conectarlas siempre había zumbidos. Con este filtro desapareció por completo!

Excelente producto. Lo que necesitaba para disminuir el ruido en las grabaciones que realizo. (Utilizo el dispositivo para conectar mi interfaz de audio a mi ordenador y evitar ruidos de interferencia).

Honestamente no me funcionó, e incluso aumento el ruido en el amplificador. No sé si sea mamonel producto pero a mí no me funcionó.

Funciona pero ya esta presentando fallas, lo compre en septiembre 2025

No funciono, es verdad que aisla el sonido pero prácticamente todo, y si usas audífonos o bocinas solo escucharas medianamente un solo lado.
