If the batteries are dead or removed... can you still use them? I know they say "fail-safe" but I'd like to be clear. Thanks!

While the noise-cancelling and the bass boost features would not be available, they could still be used as regular headphone without batteries.

The headphones will work to play music if the batteries are dead or removed, you just lose the active noise cancelling capability.

I can confirm Jeffrey's response. Also there is no need to use the noise-canceling feature when listening to audio.

You can still hear music from an mp3/iPod device if the batteries are removed but the noise cancelling and boost/amplifying functions won't work.

I spot checked these less then 4 months after receiving. ALL THREE did NOT work. I'll be contacting Waran but be aware. And keeping spare batteries is not easy with these things. You need a phillips screw driver to open, and a flat screw driver to pry the case open. Something you don't need to be worrying about in an emergency situation.

I'm sure you can use rechargeable batteries as long as they are correct size. I use mine for a while and due to climate and salt water air exposure, I remove the batteries when it's not in use. battery bleeding acid will corrode the connections. You don't want to leave batteries unattended in any unit for too long.

Ours lasted about a month with average batteries. However when we went to change them as the piece twisted off so did the wires. So it's non working. We never attempted the others. I left them up because they look impressive but no flashing lights anymore.

The batteries are meant as a backup in case power fails as I believe it often does in case of fire. In my house I've rarely had a power outage so I'm not sure how long these units would work on battery power alone. I replace my batteries every year.

One more little helpful hint though...don't leave it ON or it WILL go dead a lot quicker! Found that I had done that last night when I had a dead battery and was like, no big deal...I have my handy jumper...which I then found I had left on and was dead! My bad! :P

Yes. The only thing I've found tricky with these is getting the battery compartment open. Once I figured it out, it wasn't too bad. Don't forget to turn them off when you aren't using them -- the battery will run out! (I use them at work and accidentally left them on over the weekend. Luckily, I had a spare battery in my desk!)

Yes---I looked to make sure. You must use the rechargeable type. We have had our sets for several years and have never had to replace them.

Well let see.... I don't remember every changing the batteries since I put them in place, so if you can see when I bought them, not since then. Thanks for reminding to change the batteries. I do test then so I know they still work. One has saved me a couple times.

Yes, I was actually surprised the batteries lasted a month. Figured they'd get used up fast but not in this case. Really works too. Hope this helps.

Sorry to question your capabilities ... have you ensured that the batteries are all in the slots, in the right direction? My original batteries were dead, as sent by the manufacturer. But the new ones tested fully charged, and I was careful to place them in the slots as indicated by the arrows.Give that a shot and see.

I doubt it will ruin the batteries unless you store them in the cold, however cold batteries will have a lower performance. But these heat up pretty good when operating so I am not sure if it would be observable.

I have never had my batteries give me a problem nor have they ever ran a charge down. I do however believe you can replace them but if you have another problem like you didn't do a full charge before you ever used them, then I believe that would cause the charger to max out with less of a charge and never do a full one.

If it is totally dead it may not work. For dead batteries a manual charger works better.

I just tried mine, and it worked fine. Be sure that the button end of each battery is against the flat contact, not the spring contact, and that they are in securely. Spin them in their slot. That fixes a lot of problems. I spent 30 minutes yesterday, trying to fix a toy we had found. I put new batteries in, to no avail. I took the entire electronics apart, even soldering on jumpers to bypass the circuit board. Nothing. Finally, I put a meter on the output of the battery box. No output!. I spun the batteries in their seats, and Voila! Also, the button end of the battery holder goes in first. Be sure the button contact on the battery holder springs back when you push it in. That's really all that can go wrong with it. Good luck!

I haven't replaced them yet, but I haven't used it much either. I did have problems getting it to work when I first put batteries in it.

Mike: I am sorry, but I don't know! But, just in case you find out you can, I want to be sure you know that the batteries really "run out" quit. I ended up getting rechargeable batteries, but for what I use it for, I love it. I am sorry that I can't be of help with your question. Just me! Anne
