Expand the connectivity options of your current Plantronics H-Series headsets with the DA40 USB adapter.
With the DA40 corded USB-to-headset adapter and H-Series headset (traditionally used with a desk phone) you can now manage PC communications with superior call clarity.
Note: The DA40 is an older model. Plantronics suggests upgrading to the DA70 Audio Processor. If you would still like to order the DA40, it is still available for sale, so please request a quote below.
