The eBay bidding war came to a close Tuesday morning, and the Shure Axient digital mic made a grand total of $99,900. The auction started at only $500, but got over 120 bids in about a week.
It's an impressive price to go out at, but it's got quite the story behind it -- as we reported, Cardi asked the crowd to splash her with water at Drai's Beachclub in Vegas ... but she got pissed when someone later tossed ice and a liquid on her, resulting in the mic chuck.
The mic was auctioned off by the owner of The Wave -- the production company that owns the audio device. He told us the auction's earnings are going to 2 charities ... the Wounded Warrior Project and local Vegas charity, Friendship Circle Las Vegas.
