Not effective at all
Doesn't even work in the slightest. I purchased these as I have migraines daily (about 8 hours at a time) and am super sensitive to sound. Used them to try to watch TV and didn't even make the slightest difference and could still hear everyone talking full blast around the home. Also tried listening to music with them and no luck. Guess I have to purchase a more expensive pair..<br /><br />I did give two stars because I have super tiny ears and pretty much all earbuds pop out but these fit and stayed in, so I'll give them that.
Rating: 2 stars
