These are wired earphones from nwm, in navy blue. I bought these because I liked the Bluetooth-connected MBN001. Compared to the MBN001, the part that touches the ear is hard and cannot be removed (the MBN001 has soft ear cushions attached to the part that touches the ear), so these are not the wired version of the MBN001. They are open-ear, so the sound quality itself isn't bad, but they didn't suit the seller's needs and have been sitting in a drawer.
