Remixed the Monster Mouth Headphone Holder by philbarrenger (Thx for a good foundation!) I changed the design to have a wire hanger, USB slot and stronger overall design. Enjoy, hope it works for you. You don't have to use support but if you want a perfect print, use support as it will provide a foundation for the underside curve where the headphones sit. I used 50% infil as 60 seemed overkill. The design is solid and any more than 50% is really waste. Good Luck!
