Will these work at all if the battery dies ?

Unfortunately no, they won't.Also the wire gets easily tangled and if you drop them at least once, the plastic edge part of the headband cracks.

Afraid not! Mine failed and I only had them a little more than two months. I wish the design could keep them from shorting out.

You will unless you don't have an extension cord that reaches to an outlet from where you are outdoors. These are lights. They use electricity.

well if they come in before the battery dies, or if you actually get one that works then yea. My advice is that you should spend more money on a better brand

if you use any chargeable batteries they should work. I use others other than the original

I use them in emergency lighting and computer power backup devices. They are charged to where they will work to silence the dead battery alarm. You just don't know how long these batteries have been sitting in a warehouse, so there is no sure way to know if they are fully charged.

I'm not sure. I kept them just in case new batteries would work but haven't actually put in new batteries.

Yes. All batteries will. A battery that didn't stick out or wasn't heavy wouldn't last longer than a half hour or so.

If the battery is dead the NC won't work. Contact bose they will get you a new pair at a discounted price bc yours no longer work properly. It's gauranteed. Good luck :)

Yes they work sumultaneously but they lost power if you use one you have. Good power

No, the headphones were completely dead when I received them. I plugged them in for a test and they worked. The headphones will work with the audio cable when the power is off. I just tried this out.

Yes they will. I bought these for mine and turned out the UPS was defective. Couldn't return the batteries cause the vendor would not take them back, so I'm stuck with them.

If they stop working you have to replace the batteries. IF that doesn't work, then I don't know what you should do because it's never happened to us.

I have no suggestions. These did not work for me at all. I know of none that use a battery.

No, these may work if running on battery only. I had problems when the camper was plugged in.

No, they work fine, they just don't last a long time (when you leave them on as a night light).

They work right out of the box, except you'll have to make sure they are charged.Oh, and don't forget to open battery compartment and remove plastic so that batteries make contact.
