I believe the connector cord is a necessity for these earplugs. I've been using Zound earplugs for a year now and taken them to every festival and concert I go to. I got the connector with a pair I bought for EDC Orlando and I worked great. They fit around the earplugs in a way that fit doesn't disrupt the fit of the earplugs in your ear and they are easy to attach and detach. The cord is a good length and very durable. I also like that they are clear so most people don't even see the cord. The cord is definitely worth the purchase with if you don't want to lose your earplugs.
