A pair of Koss Bluetooth headphones. They are brand new and unopened. I'm only selling because I was gifted another pair of headphones right after I bought these. Retails at $70 on Koss' website or $100 on Amazon. https://koss.com/en-ca/products/bt539i?variant=37998719631533 https://www.amazon.ca/dp/B01N214ADI
