Query: Not the normal Plantronics quality

I own 3 other Plantronics headsets and each of them is great. This model is an inferior product that should not bear the Plantronics name. You would expect a wired headset to be clear and loud. This on is neither. Ironically my other Plantronics units are all wireless and work wonderfully. Look beyond this unfortunate model.
