how do these sound without batteries? does the quality suffer noticeably?

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

The EQ band becomes more broad with ANC OFF. With it ON the slope is + by a few Db with the slope moving more towards low frequency.

The sound with Noise Canceling ('NC') on is bright and extremely bassy, even when compared to other bassy headphones. But turn the NC off and the sound becomes very dull and much less bassy. If the sound with NC off had a little more treble - even half of the treble of a good hi-fi headphone, it would be a good thing, but it's very recessed.

Well it does change, but some might not call it worse. It has a bit less bass and treble. I prefer the powered sound, but when it's turned off or has no batteries, it certainly doesn't sound bad.

I have found these to be tinny. So what you are hearing may be normal. I do not find them to simulate live music. Their greatest quality for me is that they have little to no wire noise when moving, compared to all of my other headphones ranging from Sony to Sennheiser and Bose (which are highly overrated as well).

They should be okay .... I use them without any music on and I dont hear any hissing noise or even when I listen to music very low

These are noise isolation and they don't require any batteries and I had them for over 5 months and I think there one of the best earbuds out there and there not overprise. I recommend them

They can operate without battery but you need batteries if you want to switch on the built in amplifier.

I think the sound is pretty good for the price and size. I really like how the set folds and is easy to carry. The bass and highs are very respectable. I even use them with my cell phone. Hope this information helps.

Yes they need batteries. But the speakers blew within two songs. Its terrible.

They do not have sounds or lights. You or your child will have to provide the sounds. On the bright side no batteries required.

Well, they aren't battery activated, they're passive. But once on, they do a great job of diminishing all ambient noises surrounding- give or take a few screams, or weights dropping or clanging around you. However, if you have your music going, all excess noise is a distant memory. After putting them to work in this morning's session, I cannot tell you how pleased I am with this headset!...

The sound quality isnt bad at all. I actually dont use any external speakers, these seems to be fine. I play a lot of games and dont have a problem with the built in speakers

You can listen to music without using noise cancellation but the sound quality will drastically be reduced. Also the noise cancellation does stop one the batteries die.

Nope it's 30-something ohm so any source can easily power them. I've plugged them into my android phone, my wife's iPad, and my work computer and all powered them easily. Volume levels were good and sound quality was great. I did get a budget dac amp for my work computer and I'd say there seemed to be the slightest performance increase, but it also could have been my ears getting used to the headphones. So no, an amp is not needed.

These do not take batteries, they are not radio headphones they are just noise muffling for shooting guns or noisy environments.

They sound great to me but I'm no audiophile. Mine are in the living room, and I enjoy them just fine. I like the fact that theres' no wires (except inside walls).

I would purchase a back up just in case and keep them on a seperate mixer to adjust.without mixer they dont sound good.

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.

Yes, they work without batteries, you just won't have any noise cancelling.
