Ex Input:
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


Ex Input:
This is an excellent product. It replaces a unit that broke after some time. The old one had the battery door open and needed to be recharged. You need two AAA batteries. It's lightweight - good to travel with. Batteries can last 2-3 weeks between charging. All in all I'm very satisfied with performance - no complaints.

Ex Output:
Good Review
