Query: Well, my good luck with these just fizzled...are they different?

I have been buying these for years and since I go through about 5 a year (lose or brutally abuse them) I have always had a good few months with each. This most recent pair isn't as compatible with my Iphone...I keep getting pop ups on my phone stating as such.The device itself seems to be made differently and of poorer quality. Think I will try the other brands for a change...
