These are the shit - for under $7. The biggest problem I have with earbuds is that I have really small earholes (ha!), and so I have tried half a dozen different types, and they all either hurt or fall out of my ears when I walk. Or both.
These have an awesome design that fits in my ear and stays, comfortably. And they come in a bunch of colors. And they sound great. And they are fucking cheap. I’m thinking of stocking up for when I inevitably lose the ones I have, though these have served me well for several months already.
(I forget who it was who told me about these, but whoever you are, thanks!)
