Plantronics SupraPlus HW251, HW251N, HW261 & HW261N Corded Headset Date Codes

The date code of the Supra Plus SL family of headsets will be located on the speaker, under the ear cushion.  If a binaural model, the code will be on the microphone side.  The first number represents the month (01=January, 02=February…).  The two numbers following the dash represent the year (05=2005).  Next is the model of the headset.  An “HW251” represents the SupraPlus HW251 model and “HW261” represents the Supra Plus  HW261 model.  If an “N” is present, the headset is a noise-canceling model.  If an “R” is present, the headset has been re-manufactured or replaced by Plantronics.

This also applies to the older H251, H251N, H261, H261N corded headsets.
