Uncomfortable if you use them for sleeping.
For equipment noise, these are great.  Sanders and other noisy woodworking equipment were silenced with these easy to use ear plugs.  easy to put in and to take out.<br /><br />I thought I could use them for airplane noise and sleep, and they do well to quiet the noise.  But you can't put your head on the pillow with weight on your ears.  Very uncomfortable.  Laying on your back or reclining is fine.  But not side sleeping.
