Plantronics has announced that the Supra line of headsets will be discontinued August 15, 2008. This was the model that put Plantronics on the map for call center and business headsets. This will affect the H51, H61, H51N, and H61N models. If you have been using the H51 model, you will need to either stock up on spare units or consider migrating to the new SupraPlus H251 version. The sound quality is better and the style of the H251 appears more modern. The price will be the same for the newer model or even slightly less with most dealers. It will be sad to see the Supra go but you will now have a newer looking, better sounding, less expensive solution with the SupraPlus.
