Works like a charm
In my home recording setup I am using a laptop, connected via USB to an external sound card, which in turn is connected to a set of nearfield speakers. After upgrading my laptop I started experiencing disturbing noisy/crackling sounds on the speakers (but not on the headphones), even without audio playing.
As it turns out, this was caused by a ground loop, from both the laptop power supply and the nearfield speakers having grounded power cords.
After doing some online research I came across the Behringer HD400. It is now installed in-between the soundcard output and the nearfield speakers, and with this, the ground loop problem is completely eliminated. I am very pleased with this result.
The Behringer HD400 is compact, relatively cheap, and does exactly what it advertises: eliminate hum and break ground loops. The housing looks solid.
As always, the Thomann service was great, with prompt shipment and very fast delivery to the Netherlands.

A studio saver!
Weirdly enough, there doesn't seem to be any other similar devices around. As always when I buy Behringer I am skeptical until I plug the thing in and see what comes out... I have to say for this little black box I couldn't be more delighted!
It just does what it says on the tin: my Moog Minitaur/Roland JU-06/JP-08, all usb-ed on my computer do not make any ground loop noise anymore. And, contrary to what I read on other reviews, I cannot hear any volume drop and the sound is absolutely not affected at all! On top of that the chassis is made of sturdy metal, and after dropping one a few times, there wasn't a scratch on it.
At that price it's just unbeatable... maybe that's why other companies don't even bother making their own versions!

Eliminates GPU coil whine in speakers
I bought this because I had massive coil whine in my PC Speaker caused by the GPU. After I introduced this between my PC DAC and my Speakers the coil whine went away. Solid 10/10, does the job and it's a pretty affordable solution.

Beseitigt Brummen, aber auch jeglichen Bass
In meiner Verzweiflung, Ground Loops aus meinem System zu entfernen, hatte ich mir drei Stück vom HD400 gekauft - nach einem Dreivierteljahr aber in den Ruhestand geschickt, weil sie Bässe entweder komplett entfernten oder verzerrten. Ich verwende jetzt den Palmer PLI-05, der auch über einen Ground Lift verfügt (hat der HD400 nicht) sowie einen Furman PL-8 und ein Voodoo Lab Pedal Power 3 für eine saubere Stromversorgung.

Did exactly what I needed!
A DI box is a simple piece of kit when it comes to using it. This wee box did exactly what it said and was simple to set up and use. Matched to stereo out to splitter cables into the box and the reverse out of the box, took care of the hum that was doing my head in.
Simple and easy to use, no power adaptors to muck with and nice and tidy to look at so no one but me will even notice it is there.
Pros; Best place to get it is from Thomann. Price and shipping were both right and fast. Easy to set up. Did what it said it would do. Worked so well that I have now ordered another for another feed into my board!
Cons; So far none.

Fixed My Audio Issues
I was getting a feedback buzz or hum through my monitors whenever I played video games and this fixed the issue 100$.
Definitely worth the buy if you're having buzzing or humming issues.

Final solution to ground loops!
I had the usual mass hum on a Imac-saffireAI-power mixer-speakers, and especially when the imac was active the noise would increase frequency.
I linked this tool between the AI output and the Power Mixer input and ...voila': problem solved!

HD400 Review
I purchased the Behringer HD400 as i have encountered ground loops at some venues and practice spaces due to my use of the 4 cable method between a tube amp head (peavey 5150II) and an external pre-amp (digitech GSP1101).
This little device when placed in the send and return section got rid of the ground loop hum problem easily.
its small and easy to fit either in the back of a rack or ontop of an amp head
the only downside is there is a noticable drop in volume when using this product. its nothing to bad, 4dB at the most, easily cured with more volume on the amp head itself
all in all a great, cheep, effective and easy solution to an irritating problem. if you have ground loop hums you have no excuse not to purchase this product

I suffered from unbearable hum/noise with my Yamaha HS7 active speakers, made worse by doing stuff on computer like moving mouse. The speakerds were pretty much unusable. I tried connecting the to the same outletw with computer, to different outlet, to seperate outlets, nothing helped. I bought this babt and BAM, the noise is 100% gone.
If you're considering buying this product PLEASE learn what it is for and what it isn't. I've seen some 1 star reviews on amazon from people who thought this would remove hum from their guitar pick ups... This isn't for that kind of hum! It's for noise generated by ground loop which it fixes perfectly! I know people have certain bad expectations towards Behringer gear but this is a simple piece of equipment that does it's job perfectly.

Magic box!
Use it with a Mooer GE-200 and Baby Bomb. They would sometimes get noisy, especially in cranked live situations. But this little box solved it completely. Dead silent!
