I purchased this to replace a different pair of earplugs, but they did not fit any better. So far only one side works. They have good sound if you need the volume up high, there is no reduction to outside noise. Maybe someone will invent better, lighter ones soon. Don't bother with these, they're terrible. Sorry!

Ex Output:
Bad review

Our kids play in the pond to cool off all summer long. We had been putting it off, looking for something better looking. These work great! They are lightweight enough so they don't damage delicate water lilies, but strong enough not too bend very well.

Ex Output:
Good Review

i love the story line but it wasn't as good compared to other books I have read from this author. i was excited when my book came sooner than expected and that is why it got two stars instead of one. I still recomment amazons books though. I always get a great deal. Amazon never disappoints me!
