I like them quite well. Only been buying Happy Plugs products as my first airplugs were from them 5 years ago. They actually still work but since back in the day it only allowed you to go up to 4 hours, its a bit outdated. These are quite good, at first I was confused about the noise cancelling cause I've never had them but nowadays i do not even notice it. The quality is also good and they last quite long. Thank you
