Nope no coilwhine, not so far. I play with headsets, I also bought the Sony 3D pulse ones, and don’t regret It at all! They are good for what you pay for! And no, the controller doesn’t make noises with the headset connected. I am loving DS remake, and love the fact that you can now send stuff directly from inventory to your storage. Already put in like 10 hours or so. About the coop no worries , but would be nice to play sometimes !
