3.5mm Aux Mini Noise Filter Aluminum Alloy Shell Ground Loop Noise Isolator for Car and Home Audio System Gold Coating AUX Hum Eliminator (WD-AUX-Mini S012S)

This is my second ground loop isolator that I've bought as the first was about half the price of this one. My setup is a pair of computer speakers powered by electrical outlet and connected by aux to an audio interface which is then powered and connected by USB. The sound has a hum which is heard when cranked full volume and lowers when turning volume down but of course the sound will go down with it. The cheaper product lowered the hum by a lot but it was still there. With this one, it pretty much completely takes out the hum or if it is still there then its hard to hear it. I don't know if maybe the way this product is made is why its better than the cheaper version but the results were clear that this one worked better. I will say the price for the one item alone is a lot and should be a 2 or 3 pack for the current price but in the end, the isolator did its job for my audio setup.

I've been using this to clean up audio noise from the monitor output on my hyperX quadcast mic. Does a pretty okay job at it. A tad on the bulky side, have to take care the big black rectangle's not touching the mic. Noticeable improvement though.

A lot of times, these devices will kill your lower end frequencies and many times they only works by remove 80% of the feed back. So far, this device hasn't killed any of the quality of sound that I can tell and it removed all of the the feed back.My setup? I'm using two linux machines and an audio splitter between the monitors 3.5 audio jacks. When I plug one 3.5 into a single monitor, it works great, if I plug two jacks in at the same time to both monitors, then I get an ugly static. This device completely removed it and with a little volume tweaking, I can listen to both machines and not tell the difference as to which one is which.

Purchased two of these to reduce hum on my speakers, Did not work. If there was any improvement, it was so slight I could not hear it.

Works great with powered speakers with subwoofer and MP3 players in a very old fashioned setup I've put together

This stopped all background noise immediately in my car when using my cell phone in my car

this teenie lil noise assassin be doin some serious work cleanin up them nasty ground loop hums that be ruinin your car audio vibes. the gold plated connections and aluminum shell make it feel real premium-like, not like them cheap plastic alternatives that fall apart after a week in the sun. while it do cut out a tiny bit of the low-end frequencies, the trade-off be worth it when you aint got that annoying buzz screamin through your speakers no more.

Used with my xmradio onyz ezr. Was getting high pitched whine. After installing this the whine was gone
