they are pretty durable i'd say... have been using them while working out and sleeping, and it still works fine. HOWEVER, its extremely uncomfortable

Not sure because I've only had them a month but they are uncomfortable. Maybe my ears are small. My 18 month old was able to remove the actual bud. Pretty cheap.

I have had my first pair for a year. I unfortunately let my 12 year old borrow them and now I need a second pair.

On average they last about 30 days. It depends upon how high you have them turned up and how often the dog approaches the boundary.

Expiery date? If you mean how long do they last, mine last 6 days. The expiration date is the time manufacturer says they are safe to use them.

They last a long time, I have some from a year ago. Of course one or two of them may not last, but over all they are good.

For me , they last about 4 months. I use them in a home repair business but must add that I do not use them everyday.

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.

Lasts forever. Months, if not years. Have had mine unrefrigerated for many months, and still fine.

I've had them and use for over 6 months and they still operate. How long they will continue to work is anyone's guess.

They're good for about three years. They only last about a week so that's plenty of time.

Keep 'em clean and they should last much longer. I'm at the 6 month point right now and they are still working really well.

They are made of plastic so they will probably last quite a while. You just have to clean them up every so often.

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.

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.

I suppose It depends on the amount of usage. But I have had mine since November 13. Used moderately but not heavily. A couple times a week for 30 min to 1 hour each time. I like them. If I could afford the $40 a piece ones I would get those over these any day. But for the money they do what I need them to so and so far no sign of wear.

I've had mine about a year, use them every day for at least 3 or 4 hours. Still perfect.
