[EX Q]: 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 Q]: I use these to replace the filters on our air quality monitor. They have done a good job and are just what we needed at half the price that is typically charged. Thanks. :-)
