SAFETY RISK
These worked well...until one got stuck in my ear.  I had a consistent problem with them being too loose (as others have noted).  Then today one got stuck a little too far inside my ear.  As I was able to get the stem and pull it out, the stem separated from the main plug.  This left the flexible silicone part stuck in my ear, and I needed someone with tweezers to remove it.  Had this happened when I was further away from home or exercising, it could have gone even deeper in and required an ER visit.  DO NOT BUY.
