Using this Shure SM58 wireless microphone capsule is easy. Just connect it to your compatible wireless system and you're ready to start using it. When using it, keep it at a proper distance from your mouth to get the best sound quality. As for maintenance, gently clean the grille with a soft brush to remove any dust. Be careful not to apply too much pressure on the grille since it already has a dent. If you notice any other issues, it's best to consult a professional.
