Can I get a “Woohoo,” “Yeehaw,” “Amen”, “Huzzah”, or somethin’ cekebratory?
I bought a RodeCaster Duo and was pretty upset (to put it lightly), when I realized the headphone ports… all three ports… make quality headphones sound like garbage. Apparently, several people have dealt with this known issue and many have returned the Duo. I mean, when you pay $500 for an audio device, this shouldn’t be an issue. When I first looked for tech solutions (after attempting other methods), most options I was pointed to… costed $60 to several hundred dollars! Ridiculous! Thank goodness for this solution! NO NOISE AT ALL ANYMORE! I was honestly expecting it to dampen the noise and/or cause me to have to crank up the headphones… but, thankfully… you just plug in and SOLVED! I’m so happy, I’ve already put in another order (for the other ports).Please make sure you plug this device in correctly. If this device doesn’t solve your issue, you haven’t hooked it up correctly, or the issue is something else. There is always a possibility that you may get a defective product every now and then due to rough shipping, human error, etc… but the percentage of reviews say you are not likely to get one that doesn’t work.Anyways, thanks to this company for saving me from migraines, headaches, and irritation. I hope Rode corrects this issue in their device(s). Hopefully soon. Otherwise, the Duo is amazing. If you buy a Duo, invest in 1-3 of these (depending on your potential needs).Thank you!

5.0 out of 5 stars How to get rid of the hum! Plus a pro-tip
Reviewed in the United States on April 12, 2024
Verified Purchase
This thing does exactly what it says it does. The fat little section has an inductor that creates the magnetic field that makes sure when current (sound in this case) flows through it, it is normalized and doesn't have any potential difference (which causes the hum we all hate). It's cheap and works on the 3.5MM input that I plugged it into and no matter how much power I throw at it now, there is no more hum. A good buy and I recommend.

Pro-tip: Where do I put this thing in the sequence? The age old question of before or after that amp??? Well, conventional wisdom usually says add this inline as close to the amp as possible between the head (stereo) and amp. In other words, put this on the input side of the amp. Stereo --> Isolator --> Amp --> Speakers. This works in the vast majority of cases.

There are some instances where there might be components after the amp besides the speakers, perhaps some kind of Bluetooth adapter, or game console, or something. This situation is more rare but in that case you'd put an isolator after the amp (out put side) but as close to the speakers as possible so Stereo --> Amp --> Component X ---> Isolator --> Speakers.

There is also a third scenario where you put an isolator before the amp AND after the amp but before the speakers because you are getting two kinds of issues like potential current differences from a bad ground on the stereo feeding into the amp (corrected with the input side isolator) and then a shielding problem on the way to the speakers or another component that is leaking on to the line with a bad ground or the like (corrected with the output side isolator closest to the speakers).

Why not just add one single isolator as close to the speakers as possible to correct it all? I'm glad you asked. This is because unless you get super high quality and usually powered isolators, you can't expect miracles and the potential difference might get so high that one isolator just isn't enough to correct it all so you correct it one step at a time after each component that is causing an issue.

Bottom-line: One isolator on the input side of the amp or right before the speakers is usually enough and this thing works great for that.

5.0 out of 5 stars It worked for the iPhone with power splitter
Reviewed in the United States on April 15, 2024
Verified Purchase
I bought a used Scion for a family member to use while home from school. The car has an aux plug, but for longer trips, the phone needs to be charged too. I used a power splitter for the iOS that allows the phone to charge while also playing audio through an aux cord.

With the lights on or AC running, there was a whine coming through. This low pass filter stopped the whine and the audio was clear.

Other reviews mentioned sound quality impacts or other sound issues. If you’re using this, it’s likely you’re not running a high end sound system. If you are, then you’re running Bluetooth or USB. I didn’t notice and sound deterioration while using it.

For the price, this was a great purchase and it very worked well.

5.0 out of 5 stars Used between computer and stereo amp
Reviewed in the United States on April 21, 2024
Verified Purchase
I recently purchased a new stereo amp for my computer. The new amp ended up being very, very noisy. It probably wasn't designed well. If it wasn't the exact size I needed, I'd probably have returned it.

At any rate, I put this between the amp and the computer, and most of the issue went away. I'd say this isolator did a fine job. The rest is the crummy amp.

I was getting electrical feedback when I was using my iPhone lightning to 3.5mm audio and power adapter to connect my iPhone to my car's stereo via the Auxiliary input. You could hear the electrical interference from the engine in the speakers without the noise isolator. It is COMPLETELY gone with this device. Your ears will thank you for this! I could not hear any loss of quality in my music when installed, only made it sound better my removing the interference.

I have a verified ground loop in my house when a certain appliance is on that creates a horrible noise in any speakers connected to my Mac mini via 3.5mm headphone jack. I tried a power conditioner, and the Morley ground loop hum eliminator which were both expensive and did absolutely nothing to fix the issue. This little cheap adaptor did what neither of those could do and completely eliminated the noise. Try it out.

I have a Linux laptop and I connect a boom box to its audio output. With all my USB hub and USB connections, and possibly because of Teams, while using the same power circuit for both, the hum was too intense to be able to use the boom box. Adding the "BESIGN Ground Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable" cut the hum completely. I only hear some clicks when an audio using application starts. I have no issues listening on Youtube.
