Become useless after 6 months! - Caldwell E-Max Shadow PRO Earplugs

When I first bought them they worked ok. It did reduce shot noise but wind was amplified. The problem is at the 6 month mark, the right ear bud (that controls on/off) would always lose charge. The problem is the ear buds have to sit just right in the case in order to stay charged. If you bump the case, there's a good chance the right ear bud loses contact with the charging contacts in the case. Since the right ear bud has gone dead so many times it won't keep a charge longer than 5 minutes now.
