do they make a hissing sound in the middle of the night if they come on?

Not a hissing sound. Just a gentle whirling. I can only hear them when I'm 5-10 feet away. You can make them quieter by installing a computer fan resister inline. I'm sure they're on Amazon.

Yes, I hear ticking from time to time. The light it really low, I can only use it with my boys at night. Even then the light does not always work.

I discovered that same hiss when my TV was connected to a DTV converter box, equipped with its own universal remote. I was able to eliminate the hiss by lowering the volume on the TV's remote. I use the converter boxes remote to power on and off the tv as well as change channels and raising and lowering the volume. Note that everytime the tv suffers a power interuption by either being disconnected or power outage, I have to again lower the tv volume (and raise the volume using the converter boxes remote

Nope. It is on the loud side in my oppinion. We can't use it before bedtime as a result.

I west them to sleep, my spouse snoars a little. They do not block out all noise. I still can hear if there is a load noise or someone (the dog) gets up and moves around in the night.

I have heard them make noises as well. If you look at my review 5 out of 8 went bad on me. It may have been just bad luck but I sent mine back.

There is a low but pronounced hissing noise on at all times... That is the active noise canceling.. These are great for movies, get them you won't regret the purchase

Yes, very quiet. Maybe a very slight click when the turn on, but when they are just plugged in there is no sound at all.

Hissing may be water inside the innards where it shouln't be. I would return it for an exchange if I were you. I hope you kept the packaging!!!! Call them first to tell them you are sending it back. This device should not make hissing sounds--loud motor noise seems to be the norm, though! --SuAnn

Yes, ours just began doing this last night. We have had these for over a year and all 3 of our room units began doing it the same day. I am still trying to track down the reason behind this.

I have been using these for about a year. One is in my master bedroom and even with everything off in the house at night, I've not noticed any sound from it.

They are sort of loud when they are working. however one of ours quit working first day we opened the box. I would never by this item again.

It sounds like a low humming. My son uses it every night, all night since I purchased it and still works great, almost a year now since he's had it

I think so, but don't buy it....I have returned mine. It beeps and squawks -- eve i the middle of the night, for no apparent reason. Very annoying...to say the least.

I seldom experience a hissing or crackling. When I do I just scan and the noise goes away. This happens very infrequently to me. I rarely have any problems with hissing. I found out a while back that if you are too close to the TV you may experience a hissing. Just move a little bit away and it will clear up.
