Yes. One AAA. Just open the cover on the side with the on/off switch and there it is.

Yes, they take one AAA battery. They should be switched "off" when not in use to preserve the battery by sliding the yellow switch on the side. They are still functional when the battery is dead; the noise reduction feature will not work, though. Hope this helps :)

They do take batteries. I have only used them on a few flights so I am unsure how long they last. I believe it is AAA batteries but not sure at the moment.

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

Sound great. I use mine without batteries most of the time. Turning them on does add a little bass boost.

I can't remember for certain but am pretty sure they came with batteries. Sorry about not being too helpful.

Hello,I see you had a question, to answer your concern: these speakers donot require batteries, nor do you have to plug into a electrical outlet. A USB plugin and sound input is all that's required.

If I recall correctly they take AA batteries. The battery life would depend on the batteries, I guess. We don't use them for very long at a time so I am sorry I cannot be of much help.

It isn't technically noise canceling considering there's no need for batteries. However, the sound isolation is similar to noise canceling due to the design of the cups. They are really great headphones and keep out most sounds. I use them all the time. Plenty of times my girlfriend has asked for favors that I never heard because these headphones are so boss.

They are not too loud. But warning my kids only played with them for less then an hour before they quit working. They only work for about 20 mins at a time before they freeze up. The straps also kept slipping down their arms, they got frustrated and won't play with them anymore!

They last pretty long. Make sure you use quality batteries, like Duracell or Energizer. Don't forget to turn them off when not in use. I don't want to attempt to guesstimate how many hours, but we really don't have to change them often. If they start making funny noises, time to change batteries.

There are no batteries in these. Strictly over the ear protectors and they work good.

The seem to be just normal earmuffs blocking 82db and above when there are no batteries but I can not say this for sure because I have not field tested them without the batteries. My guess is that they work the same when there are no batteries or if they are dead, as they do when the volume is turned down while they are on; they cut out 82db and above without amplifying sounds below that range...

I don't know, Melissa. They might sell rechargeable hearing aid batteries. It would make sense. I suppose you could do a search on

No they do not. They are not noise canceling or wireless therefore they do not require batteries.

yes, the batteries works very well, I can tell after 4 days when the batteries are getting low the sounds are not as loud.

I don't know how long the batteries last because I returned the speakers. The volume was so low they could be barely be heard. I even called Acoustic Research customer service, thinking I did not have them properly set up or connected; I did have them properly connected. Don't waste your money. They look great, but produce very little sound. In fact, they could not be heard at all, when people carried on a normal conversation.

No. No sounds, no lights. 4 year old Nephew loves it all the same.Thanks for the question :)

Yes. They use 3 AAA batteries. They get a pretty long use out of them as well.
