How long do they last?

They stopped working before we even got to the concert they were bought to wear at. They turned them on an within hours they were no longer working.

It depends on if you're using them continuously. I would say you can get about 8-10 hours (though this varies). You can extend the life by removing the batteries when you don't need to use them. You can also buy replacement batteries, but they tend to be expensive so I would recommend buying new ones.

I was at a festival and they lasted for at least 6 hours. You can bring batteries if you're concerned. They didn't really stay in my hair though. I ended up clipping them to my fanny pack.

They are hit or miss. Some last just as long as Duracells, but for the most part, they do last long at all.

I have had mine for a while now, and they are still going strong. At least 5+ months.

During the warmer months, they've lasted 2 to 3 months. Winter time, I would check every 2 weeks depending how cold it gets.

They seem to last a long time, I bought the 4-pack two months ago and I'm still using the first one. I really don't use them a lot, tho, only when I open up my pc case.

I only purchased them about 6 months ago so I cannot tell how long they will last. I highly recommend them because they work great and is very well made.

No, I have not. And so far, I have not had any problems with them lasting for weeks and even several months.

I'm not sure entirely, but the computer will complain if they are too old (planned obsolescence). They have lasted for anywhere from 1.5 to 2.5 years has been my experience.

I don't know how often you use them but I have had some for up to 6 months and haven't any trouble with them. Hope this has been helpful. Thanks Bert

I read somewhere that these are suppose to last for up to a year. Just make sure you keep them stored somewhere cool.

Mine last between four and five days depending on how long you have them on.

There is a little variation with some but, on average, I would say about three weeks. I've used them for about a year in two separate locations in the house. Hope this helps.

I've had some over 6 months and they are still good. They have kind of a wax outer shell so I think they would keep for some time.

Not sure exactly, but I rarely replace them, I would say over six months at the very least

I'm sure they would last beyond a year. I've had mine for maybe 6-8 months and some have changed shape a little, but otherwise they are all perfectly fine!

They can last for years. I uploaded a video of mine after a few years of use, and I use them often: http://www.amazon.com/review/R236EXQTVCUJA4

I believe they are supposed to last for one year. I have been using mine for over 6 months now and it has barely changed in size.
