Bring exceptional audio quality to office and contact center conversations with the Plantronics® DA45™ USB-to-headset adapter. Paired with any Plantronics H-series headset, the adapter supports wideband audio for better call performance—so softphone users can conduct clear conversations with fewer repeats and lower listener fatigue. The DA45 reduces echo that is inherent with VoIP communications. Convenient inline controls provide fingertip access to volume, mute, and a call answer/end features. Facilitating a single headset for use with both softphones and desk phones, the DA45 adapter’s Quick Disconnect™ feature allows the headset to detach without losing the call.
