Plantronics DA40 USB Entry Level Adaptor for Plantronics Headset

Plantronics DA40 provides exceptional sound quality and the flexibility to use any Plantronics headset with VoIP SoftPhones. USB port connection provides universal compatibility and independence from the PC’s soundcard, allowing the PC’s speaker, not the headset, to ring for call notification. Sound quality is digitally-enhanced with Plantronics proven SoundGuard Plus and Call Clarity technology, whilst Digital Signal processing (DSP) suppresses the echo sometimes experienced with VoIP.
