Cons:they won't stay on so I have to re-insert them about every two minutes.
I got these for two purposes: airplanes and exercise. They are a problem for both. Yes, the plug does block some outside noise and the sound is good. But trying to keep them in my ears is SO frustrating. They fall out constantly. I can't jog with them. Plus the squishy plug part isn't attached to the rest of the headphone so that falls off very easily. When I look in my carry-on luggage to get them, the foam plugs are missing. Bottom line: get something else. The only way these would please me is if I'm sitting still, at home.
