They don't make any sound at all. They do have a small red light that flashes occasionsaly, to tell you its working.

These make very little noise. You have to put your ear right next to them to hear them once they are in the ground. They won't annoy you or your neighbors.

I do NOT recall any such sounds. I use the unit only occasionally, last a few weeks ago.

No. they do not have microphones or anything of the sort. They only have IR receivers as they have an IR remote with them.

Depending on how you set it it may make a small noise. Normally though, no.

Hi Katie,No not really. They make a little noise, but nothing unbearable (I didn't think at least). Hope this helps.

Yes, they do make noise. You can hear a buzzing noise but you can only hear it if you are near it. It definitely would not disturb your neighbors.

No. But when you are listening to music with them you cant hear anything else

They do. Tested mine 2 days ago and they muffled the sound while still allowing me to hear someone walking up behind me

Elisa, they do work without any music playing but you do hear a not more of the surrounding noise. The more expensive models I have tried do a little better job without music. But not considerably better.

Not at all, they are remarkably quiet. You can barely hear them even when you put your ears close. Great fans.

No they do not light up or make noise. They are just ocersized figures from the real steel movie.

Don't think so. They aren't very loud sounds either. Especially for a ckassroom.

No, they are a cloth material. They do not make noise but just like anything, they become more soft as you break them in and give them a wash.

I can't say if it's normal or not, as I don't know any beyond my own... but mine do not make any noise.

They don't make any noise. They are just duds shaped like a loaded bullet with a plastic cushion for a primer so you can dry fire pistols with strikers.
