Q: Is it possible to use a commercial grade binaural headset with my cordless phone?

A: The headsets Plantronics designed for cordless phones are all single ear, either headband or over the ear. Their power requirements are not as intensive as commercial grade headsets. Cordless phones in general do not pull out enough power to make commercial grade headsets work properly. Also, the cords of the commercial grade headsets do not shield from the interference as well as those made for cordless or mobile phones.
