The brother moved out of the house for months now. He s starting his own family and starts buying things at their home. He is done buying furniture stuffs. Now he is investing on their sounds system. Knowing my brother,he would surely buy the best sound system for their home. And to make it more fun my brother wants to add the irig keys to their sound system.
