Guys have any of you noticed any issues other than the triggers not rumbling when your battery is needing charged? My mates headset was playing up and we could all hear his crackle a bit when he spoke, he then purchased a new headset and it still crackles and it went completely off earlier. I thought it could be something to do with the battery dying and asked him when he last charged it. He said ages ago, I'm thinking it could be the battery??
