I just received mine- is it supposed to making a hissing / crackling sound?

After 1 week, it hissed and crackled and burned out. I think that it had a short but, I did not attempt to return.

I've never noticed mine to make any noise at all. When I checked again just now, I put my ear right up to the camera and could barely hear a little hum.

No, my unit does NOT make such a sound. I DO think it is faulty. Please return it, ASAP, but be sure you tell them why.

No it does not make a crackle noise but the flame looks real. One thing I would do is reconsider buying this one. Mine died after 3 months of use on the lowest setting and repairing it costs more than the original purchase price. After reading the comments, I found that I was not the only one who had their unit break down after a few months of use.

no it is not normal. I get the hissing sound until i turn off the puck(i.e. I touch it). The hissing with power on appears to happen with most computers and speakers, until the speakers are turned off.

Mine is definitely silent. It only buzzes/clicks when there is a power fluctuation, which is very rare. I'd suggest to check your line voltage at the outlet before condemning the unit. If that's ok, then yes, your unit may be faulty.

If its the hissing sound you're talking about, that's the noise canceling pink noise. Since the processors aren't fast enough to real time noise cancel, it uses a frequency that cancels most ambient sounds, but when exposed to a constant outside noise for long enough (fan, car engine at idle), the mic picks up and cancels that outside frequency. If it's making some other type of noise, then it may be a defect.

Mine, which I bought about four months ago, does not make any noise. You might consider returning it. That is my only advice.

i didn't send mine back, I took the screen off and pressed the speakers. the popping and crackling is gone, every now and then it comes back, so I press them again. eventually they will fail I assume, but what do you expect from something so cheaply and poorly made?

Mine does not have this high pitch you're talking about, just a loud hum, rather like a window air-condition unit. Since it is in my basement, it does not bother me. Maybe you have a bad unit?

Ours makes a small cyclic hum. You can hear it. It doesn't bother me, but everyone has different tolerances.

In my setup there is no hiss or background buzzing in the background. I can have the volume knob at any volume setting and its dead silent with music off. The hissing and external noise might also be coming from your sound card, if your using onboard sound. I have my emotiva plugged into a Sound blaster Z gaming sound card. Hope this help answer your question.

Hello Kitcat, Thank you for contacting Tools for Wellness! The VI-2500 does have a subtle whisping noise and sometimes you'll get what sounds like a crackling noise. Its not particularly loud but is some what noticeable. Most ionizers have the same type of sound. If its loud you may have a defective unit. Let us know if we can help. Thank you!

Mine only makes the noise for a few seconds when I first plug it in. Other than that it is quiet for me.

No, not at all, sounds like you got a defective one, mine is still working GREAT!
