Bluetooth Headsets: Date Codes

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

BackBeat 903/906

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.
