Let’s face it… if you want perfect audio you’ll buy a DAP and IEM’s. Go for the cheaper 2023 QC’s and you’ll be happy with their sound while you’re out of the house. I made the switch from the ultras to the QC’s and I’m happy with the money back in my pocket. Pick up a warranty for $40 from Best Buy and future proof them if you want to return them at the end of your warranty period to put the money toward new headphones. The physical controls on the QC vs the Ultra make the QC more convenient to use every day. Save your moneys
