Bluetooth Headsets: Date Code Location

Headsets are listed in alphabetical order. Date Codes consist of one letter and one number (e.g., A9).

The two digit Date Code on this headband is located on the left side, which also has the on/off switch. Look at the inside surface (facing your ear) and you will see a printed "CE". Above the CE are four lines of very small print. The Date Code is on the third line.
