WeSC and the Bread & Butter tradeshow have come together to collaborate on these Maraca headphones as part of the B&B for Charity Project. The headphones look pretty slick with the all-black colorway and subtle branding that should delight any audiophile worth his salt. Due for release at special B&B charity booths next week, the headphones will be available for three days only, and all proceeds from sales will go directly to charity.
