I have:

1. Lost a pair 2. Lost one bud from a pair 3. Washed them 4. Swam in the ocean with them 5. Had a pair generally degrade

So I know once I buy a pair, I'm good for about a year until I need another. That's also when I tend to notice the new features. :-)

I won't use them in a plane because I know I'd lose them. Carry a separate pair of wired noise canceling earbuds for flying.
