Vsing offers several VIP Subscription packages that unlock unlimited access to our new releases, plus our special sound effects options. *Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription.  Your iTunes account will be charged a renewal price equal to that of the original subscription within 24 hours before the end of the current period.  Be absorbed in your music by singing in a private room, getting connected with others via chat message, or sending your friends gifts to show how much you like their voices.  Billions of free HD songs for genres like Rock, Pop, Rap, R&B, Electronic, and Country Music are available to our users!  From time to time, you may have new visitors in your room, and when you aren’t in your room feel free to visit other rooms to hangout!  No need to hide your talent since Live Karaoke allows you to show your capabilities without worrying about finding a place to shine.  Subscription purchases are charged to your iTunes account upon confirmation of the purchase.  Subscriptions are non-refundable and may not be canceled during an active subscription period. Having trouble?  Thanks to our amazing technology, studio class recording quality is no longer a dream for our beloved users; ALL you need is a set of earphones to enjoy.  All subscriptions will AUTOMATICALLY renew unless auto-renewal is turned off at least 24 hours before the end of the current period.  You are free to host a karaoke live party that crisscrosses the world.  You can manage your subscriptions and turn off auto-renewal by going to your Account Settings after purchase.  Our application is developed by genius technicians, who bring amazing recording sound effects to the software.  In Mic Grab, test your skills by seeing how many songs you can sing while competing with your friends.  Feel free to join and open up new paths to friendship!  Isn’t it cool to express yourself, and meet new people all around the world through singing?
