They work great for quiet environments and the locking ear buds are awesome at keeping them in your ear.

Call clarity is wonderful, I can talk on the phone in a loud shop environment

They are adequate, I just couldn't seem to get mine to be loud enough in noisier environments

Not very effective In a loud environment (trick engine)

Was good in beginning but very hard to hear when in Loud environment.

I can see this as a pro or a con depending on the situation but while the earbud will stay in place very firmly with the rubber ear crevice, the bud itself does not make a great seal in the ear, as a result you'll find the volume needs to be turned up higher in louder environments but at the same time, when music is paused, you can leave the buds in and hear everything around you almost as clearly as if they were removed

RIGHT(R) rubber on BOTH EARPHONES when they should be RIGHT
