The Plantronics® range of adapters provides the flexibility to use any Plantronics® headset (P or H range) 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.

With the top-of-the-range adapters – DA55 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.
