If you plug your phone/ipod/etc to a charger, does using this create a ground loop and buzz/hum?

Yes unfortunately it does, but for the price it's a great product! Would highly recommend

Don't know that I've had that problem but i got a ground loop isolator as well. They're pretty cheap

Yes it does. Not a huge deal though. Might get a ground loop isolator in the future.

I've successfully plugged both into a power source without humming. However, I suspect it may vary from power source to power source, and maybe even from unit to unit. Your milage, it might vary.

If you're 100% sure it's not the source, then yes. I don't have hum unless I am on high volume but I have had a lot of source hum from my sound card. So check that out before shipping it off.

Nope - doesn't make a peep of audible noise - just an internal relay clicking after it does it's initial check and switches to charge mode.

Yes, mine makes a buzzing noise when it is charging. It is not very loud, at least in my garage, but I can hear it pretty clearly when I put my ear against the box.

Yes for sure. Seems like if it's on and I plug it in that it turns off and I need to turn it on again but other than that quirk it charges in car usb outlet, iphone charger plug, any usb outlet that has power.

Yes, But I don't understand why that would ensure a "no buzz" scenario. Perhaps your home radio needs to be looked at as the culprit!

Yes you definitely can. I have not experienced any hissing or change in sound quality when I'm charging it and playing my music.

The unit itself does not make a sound. Rather the blue LED indicator light shows charging activity and remaining charge. Your device that is plugged in May make its normal charging chirp. For example I've charged iPads, iPhones, an iPod and a windows phone and all make a charging sound once plugged in and you turn on the unit (don't forget to power it on of course) �. Hope that helps.

No, not at all. Make sure you are connecting to correct charging source and chords don't have issues.

Also, if possible only use equipment with a grounded 3 prong plug. Without the third ground connector on the power cord the equipment can't be properly grounded and so ground loop hum will be harder to avoid ...

i doubt it. from what i know having your equipment plugged into different circuits would only make the hum worse. in any case if your equipment hums it is probably not worth spending this much money to fix the problem. good equipment doesn't hum no matter where you plug it in. i suggest getting equipment that uses balanced ( XLR ) or digital ( Optical / Coaxial / XLR ) interconnects. Regular consumer unbalanced analog technology is inherently inferior and was never designed for high performance.

No. It boosts the sound and as a result it can actually pick up noises like a buzzing sometimes. I wear a noise canceling headset to cut out background noise.

Same as if you were plugging it in to charge. If your volume is on it will make the charging beep and light up red. When you remove it no noise.

If I charge it at the same time, it will have the buzzing sound. Otherwise, it is perfect and sound great.

I'm not sure... I don't even use mine because it makes a humming sound every time I plug it in. I'm afraid it's going to spark a fire.

I used it for my I phone and never had a problem with that. I always heard it ringing. My issue was with the plug in the back. Sorry, hope this helps.
