I know we’ve had “recommend some earbuds” threads before, though I don’t remember any of them specifically addressing the issue of durability. This one, however, started out with its OP complaining about his Skullcandys not lasting. (There’s also the issue that some models may have been discontinued or had their price change, and new models been introduced, since those older threads.)
Klipsh Si-4. About $80 bucks. Just outstanding. Over the years I went from the cheap-ass Apple supplied bud with an iPad, and to progressively more expensive buds. And I heard a significant improvement every time. After I got the 4 Si, I’ve tried pricier ones, but I haven’t heard any sound better.
I’ve been using my Jaybird Bluebud X earbuds for about 3 or 4 years now. I use them in the shower, while walking/running, cycling, etc. They are pricey, but I’d buy another pair if this one somehow failed.
I wish I could be more specific, but based on one of these threads a couple of years ago, I bought a couple of (some specific model of) Panasonics, that were only in the $20-30 or so range. The first pair lasted almost a year, which is unheard of, and died only because I got them caught in some wiring as I was starting the snowblower, and one speaker got ripped off the wire. The replacement pair has lasted, again, almost a year without a hint of trouble, and I wear them constantly every day. They’re fantastic. I have a picture somewhere of the packaging so that I could buy more if they ever wear out, but my phone’s downstairs charging so I can’t look right now.
