Tune Them Out

When the Hubby and bro-in-law sit down and talk djing I can only handle so much before I have to tune them out.  Don't get me wrong I'm a big fan of the music, but a lot of the equipment and stuff is confusing to me.  Like when they were talking about how my bro-in-law could save on ns7 at musicians friend I have to tune them out. I have no idea what that is or why he needs it, so it's like a foreign language to me. That's where I am tonight, stuck in tune out mode while they ramble behind me!
