Koss collaborated with San Francisco-based Drop to develop the KPH40X Utility, tapping into its unique “Community-Driven” commerce platform to inform the product. 

Featuring the unmatched sound quality of the original KPH40 Utility, the Drop x Koss KPH40X Utility features uncompromising connectivity with the ability to connect to USB-C, Lightning and standard 3.5mm ports (USB-C and Lightning Utility Cords sold separate). 

KPH40X Utility features a updated aesthetic with a blacked-out body and interchangeable red and blue ear-pads giving KPH40X Utility a retro with a modern mindset. The Drop x Koss KPH40X Utility is available exclusively at Drop.com
