Logitech makes both wired and wireless headphones for use with portable MP3 players. The wired version installs simply by inserting the 3.5mm plug into the Headphone or Audio jack of your player, but the wireless version takes a few extra steps. Before you perform the installation, the wireless receiver and headphones need to be charged for proper use, and the adapter needs to be fitted for the specific player. The two components then must be connected with each other before they will work.
