Kratos S5 Constant Hissing/Static sound

[Mr Arky]

I recently purchased the Creative SoundBlasterX Kratos S5 Soundblaster speakers, and as soon as they are on there is a hissing sound which wont go away, weather its just on desktop, or even watching videos/listening to music.

I have tried:

Plugging into a different socket,
Setting up in a different room,
Setting up without the computer plugged in,
I have W10, so it installed drivers automatically, but I still went to their site and reinstalled the up to date firmware and drivers.
Even bought a second pair to see if something was faulty,
Turned down all volumes to the lowest possible - and if its on the highest volume its insanely loud.
It also still happens when the volume on the mixer is muted.

I had a more simple Logitech set of speakers before which did not make the hissing sound, or if it did it was so quite that I was not aware of it.

I'm truly at a loose end here! and the hissing is so loud and I can't really find anyone else with the same issue, after going through the trial and errors.

I've stuck with headphones mainly for years now, is this common in speakers?

Any help or suggestions would be greatly appreciated.

Thanks

I have my headset plugged to the SBZ and the Kratos connects via USB.
I find it strange though how I have 2, seperate Kratos S5's and both have the same issue,
and if thats the way they sound normally then that kinda sucks.

You get a hiss with all speakers to a certain extent, but it shouldn't really be heard unless you have your ear close to the speaker.

From what I can gather, they have USB and 3.5mm auxiliary input. Have you tried the 3.5mm and disconnected the USB cable?

If you still get hissing when using 3.5mm from the sound card rather than USB; what about trying them with a smartphone or tablet?

Connecting to a mobile device is best to test them. Rules out whether the noise is coming from the PC and whether it's a problem with the speakers.

If you still get hissing whether the speakers are connected to anything (including mobile devices) or not, then you may have been unlucky to receive 2 faulty sets (possibly from a bad batch).

Sorry for delayed response,
I hear the sound even when leaning back in my chair,
I get the hissing as soon as the speakers get power, weather its connected to the PC or not, and these speakers are supposed to be conneted via usb, though I see a possibility for an adapter, I don't belive it would make the already present hissing sound disappear.

I guess its looking like I have a faulty batch, as thats the only scenario which seems likely by this point.

I have contacted Creative for any final solutions then may have to get them returned if all else fails.

Thanks for the replies!
