The I paid $25 for these pretty decent ones, they go for $60 retail. Everything was fine and then I remembered the third reason this is trash technology: the screen thingie always comes off, or gets gummed up and has to be taken ‘ off, making it sound like something I wouldn’t even pay $5 for.
If it isn’t that, earbuds will either not stay put, or I’ll lose one, just one.
You can get third party tips for differently sized ears, but I've been using the same set of cheapass koss porta-pros for a decade now if that's an option for you.
