Dont work well
The main reason I bought these was because I have neighbors who play loud music almost every week. I wanted to be able to study and sleep in peace. If your curious I'm in a house not an apartment. So it has to be pretty loud for us to hear it in our home. We have called the cops many times, but nothing ever happens to truly stop it. I have tried the foam ones and they were ok but I could still hear them. These are worse than those. I had hope but.....naaaa. I don't know what to do now with the rest. I waited to long to try to return them. I wish I could recycle them.
