The drill is to pinch and squeeze it until it is as thin as a stick put it in your ear canal and wait for it to expand to make a perfect seal

But you must know how to properly put them into your ears

I have small ear canals and have trouble getting normal earplugs to compress enough to get all the way in my ear and actually cancel out any noise

I dont find these to be uncomfortable at all and they stay in my ear the whole night two things i need from my earplugs

The only thing that i have noticed is sometimes at night the device comes out of my nose

Posted by a reviewer on Amazon

I dont know if i am pulling it out in my sleep or if it falls off

Posted by a reviewer on Amazon

The just shut the noise out completely

Further they fit well in your ear and dont fall out during a nights sleep
