    1.0 out of 5 stars Faulty, and unusable regardless of faults

    Both units are faulty. One has no connection with the left channel, the other has the left channel significantly quieter than the right. Both significantly degrade audio quality, it causes distorted hissing and clipping sounds in any song with any kind of highs. Very unfortunate because it did eliminate the buzzing, but is otherwise completely unusable.

    Used it to get rid of buzzing from the headphone out of a digital piano and it worked really well for me. It reduces the overall output volume a bit but in my case there was enough amplification available to counter that reduction.

    5.0 out of 5 stars Absolutely Fixes Ground Loop Noise
    Reviewed in the United States on May 9, 2024

    It's electronically a stupidly simple circuit any beginner could make, but the trick is containing it within a professional-looking, commercially-made housing that isn't made from a pill bottle or other reused container, and doing so for less cost than getting TWO of these for.... what'd I pay, eight bucks? nine?

    I have a Jeep with the aux audio port into which I have wired my amateur radio transceiver via a 3.5mm TRS patch cable. The alternator whine only came through on the receive audio, never went out on transmit, and honestly it was quite tolerable, but I really wanted to get rid of it. Knowing the circuit was a simple design, I figured it would be quite inexpensive to purchase a commercially manufactured product, and I was correct. Installation was a breeze, and fortunately I already have the radio bracket close enough I could zip-tie the filter to the bracket and keep it secured and out of sight. You can barely see it!

    It definitely works. After installation, I couldn't hear any whine. I'm not saying it's zero, but the engine with the tops off and windows down was loud enough that I couldn't hear it with the filter installed, whereas the whine was loud enough to hear through the engine noise with the filter not installed.

    I don't 100% understand the theory myself, but essentially it's a 1:1 audio isolation transformer inline that disconnects the lines electrically (DC) but still allows audio (AC) to pass electromagnetically via the transformer windings and core, thus breaking the otherwise direct connection between audio equipment and a variable ground potential (voltage on the audio ground instead of chassis ground) from the alternator.

    Anyway, bottom line, it works, and I have two for the same price some sellers are selling only one.

    The media could not be loaded.
    This is a pretty good product, nothing too insane, the value is good, the installation is extremely simple, and to be honest, I thought it would be way bigger, the size of it is very small which is what I like, I stream on twitch and this helps a lot with hissing sounds and buzzing. Sounds whenever I use my mixer. One little problem is that it does make audio slightly quieter. Other than that, it does what it says it does, and it’s nice to have. 👍

    5.0 out of 5 stars Worked for me and removed the hum noise
    Reviewed in the United States on November 28, 2024
    Verified Purchase
    Had a 4 channel headphone amp and every device connected to it had a hum.
    Installed this on every input and got a clean sounding system again.
    Truly don't understand why these aren't built into every audio input gizmo. If it's a known fix, design it into your stuff and the. I don't have to buy extra gizmos, cables, and connectors.
    This had two 3.5mm jacks on it, so had to get 1/4" adapters at all ends to make it work.
