What are the DA40, DA55, DA70, DA70, DA80?

Updated by Hayden Everly on Feb 14, 2023

With the DA Series adapters, you can use your existing Plantronics "H" Series headsets as USB headsets that work with PC based VoIP Softphones. These products from telephony manufacturers such as Siemens, Tenovis, Nortel or Avaya. They will also work with applications such as Skype.


The DA40

Includes a USB-to-headset quick disconnect adapter with crisp, clear sound. Bring the audio quality and the comfort of H-Series headsets to Voice over Internet Protocol (VoIP) softphones. This is now DISCONTINUED! Suggest the DA70 instead!


The DA50

USB-to quick disconnect -headset adapter featuring Digital Signal Processing (DSP) for digitally improved sound.


DA60

Offers all the same features as the DA55, plus an in-line mute switch and PerSono Call 2.0 software for great control of voice and audio quality.


DA70

Offers all the same features as the DA60, but does not feature in-line mute and volume controls.


If you need in-line mute and call control with their headset adaptor, you will want a DA80. These are not currently available from us, but may be out there somewhere.
