Not on 2 and 4!!!
These work really well. I was blasting the music in my car and I could still here the music very well without it sounding muffled like with foam ear plugs. They also don't cut out the low volumes so conversations still sound very normal. One other thing I liked about then is that they're very comfortable in the ears. People also seem to really like the metal container and is pretty cool but I'm not picky when it comes to that. I would not use these for extremely loud concerts like a death metal and instead I would use the normal bright orange foam plugs. Even with that said these will be my go tos because they're a lot more practical and these signs better. On top of that they have very good customer service, I realized that I would prefer the long stem ones after reading some reviews and accidentally ordering  the short stem ones they gladly sent me the long stem ones and sent me an envelope to send the old ones back in while paying for shipping. Long story short these are a surprisingly a great product with great customer service and I would definitely consider what stem option to pick from before purchasing from them.
