Pros: Worked great for the price when I got them. I used them for running and working out mostly, and the ear buds stayed in better than most ear buds I've used in the past

Cons: Like other people have said, after 3-4 months the volume would randomly change. I had to giggle the volume switch to get it to come back. Eventually the right ear went out altogether, and the inline controller sends the "mute" command to my phone 5-10 times in a workout.
