These are a must have to keep dirt or water out of the female ends when not in use
I use these dust covers to cap my Nexus plugs and as a retainer for my headset extension harness. Works great as advertised.
Totally worth it if you don’t want water and crud getting into your jacks when not using them!!
I use in my 4 seater when nobody is in the back or when I wash for extra protection. Never had a problem love them!
