I'm looking for earbuds or IEMs to use with my phone to listen to music while I'm walking around outside. Low isolation so I don't bump into people or fail to hear a car. Sturdy so they won't get destroyed in my pocket when I'm not listening. Comfortable for obvious reasons. They shouldn't easily all out of my ears, as some earbuds do. Sound quality doesn't have to be more than decent, given low isolation and ambient noises. I don't need a built-in mic.
