do these just inflate or is there some sound or echo to them?

Barbara H.,These are only inflatable microphones. They do nothing but sit there and look nice. I bought them, along with some inflatable guitars, as studio props for a photographer's meeting. I might get some more and hand them out as party favors.

these take a normal pump, you can inflate by mouth or with a pump, it does need the attachment on the pump to fit the valve but most pumps come with that attachment.

They are deflated. If you are a first time buyer, you will want to buy a ball that comes with a pump.

I haven't aired them back up, as another user suggested, so find them extremely soft. I would think they'd pale in comparison to something like a tennis ball or Trigger Point ball on your back. However, I haven't tried to really pump them up and see. Good luck!

none of them are particularly quiet in my experience with a usual rough vibratory tone made worse if they are operating under any back pressure. Run it free in a bucket and see how it sounds. If still loud then that's the sound of the pump.The maxijets are worse

Yes they do' but the air is not helium. This is a good pump. It will do the job very fast.

I have two of these and have never noticed that before, but yes indeed they do have air coming from that hole while the moror is running! I LOVE these compressors. They are quiet and reliable.

Unfortunately they do not, they're made of a soft foam and have very minimal bounce if any. Hope that helps

I used an air pump. Never saw where it said otherwise. Took a matter if seconds to inflate.

They aren't loud at all! They make a very dull sound. If you have a large load in the dryer, I wouldn't say that add any noise at all. If it's smaller, you can hear it some, but it's not like putting tennis balls in there. They are very soft.

They deflate like a car tire. Take a small screwdriver and press the tiny stem that is inside the valve stem.

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.

When you unroll it, it inflates. You have to do this a couple of times before it fully inflates.

No. They doesn't make any sound. They are good. I am using them from around 15 months. All four are still working.

There are simply airpockets in the foam that full with air when you unroll the mattress and open the valve. After an hour or so, we give a few good blows to fully inflate it.

Not at all, be careful not to let the air go in all of a sudden then it might sound (funny) But the pump itself doesn't make any noise.

There is not but honestly it takes me about 2-3 minutes to inflate both chambers with the hand/foot pump provided. Hope this helps
