If your company already bought Plantronics H-series corded headsets for desk phones, and now needs those same headsets to work with computers or softphones, you don't need new headsets — a DA-series adapter bridges the gap. Here's the full lineup, from basic to call-center-ready.
Quick answer
Why a DA-series cable instead of a new headset
If your company already standardized on Plantronics H-series corded headsets for desk phones, and your work has shifted toward computer-based calling or softphones, a DA-series cable lets the same headset serve both purposes — no need to buy an entirely new headset just because your communication method changed.
DA40: the original basic adapter
Connect the QD end of your H-series headset to the QD end of the DA40 cable, plug the USB end into your computer, let it install any needed drivers, and you're set. It's the most economical option in the lineup, without inline volume/mute controls or bundled call software.
DA45: adds controls and call software
For better value, the DA45 adds inline volume/mute controls, call answer/end, support for wideband audio, and echo management, along with the PerSono call software program.
Myth
PerSono software is still the current tool for managing Plantronics DA-series adapters.Reality
PerSono is an older Plantronics call-management software, from well before the more recent Plantronics Hub → Poly Lens → HP Poly Studio App lineage. If you're setting up a DA-series adapter today, confirm with our team which current software (if any) applies to your specific model, rather than assuming PerSono is still the active tool.DA55 and DA60: for older Polaris-connector headsets
If you're still using an older Polaris-connector headset, the DA55 connects it to a computer without requiring a whole new headset purchase. The DA60 does the same but adds the inline volume/mute controls, call answer/end, wideband audio, and echo management found on the DA45.
DA70: the current simple entry point
For any Plantronics H-series headset, the DA70 is the current basic option — a straightforward QD-to-USB-A configuration with no extra controls. Plug your H-series headset in, connect to your computer, and you're done. Affordable and practical for larger deployments where simplicity matters more than extra features.
DA80: for call centers needing hands-free controls
The DA80 adds volume control, microphone mute, answer/end, and hold (depending on your softphone application) to any H-series headset connected via USB-A. Strongly recommended for call centers or anyone taking constant calls who needs to adjust volume or mute without reaching for the keyboard or mouse.
DA90: for 6-pin "D" Digital headsets and managed deployments
The DA90 is compatible only with 6-pin Plantronics "D" Digital headsets — model numbers ending in D, such as HW510D, HW540D, or HW720D. It's built for call center deployments that need fleet-level management: usage monitoring, quality feedback, and inventory tracking, whether on-site or remote, through Poly's current device management software.

How do I connect my Plantronics H-series headset to my computer?
Use a Plantronics DA-series adapter — connect the QD end of your headset to the QD end of the cable, then plug the USB end into your computer. The DA70 is the current basic option for this; higher-tier models (DA80, DA90) add controls or fleet management for larger deployments.
What's the difference between the DA70, DA80, and DA90?
The DA70 is a basic QD-to-USB-A adapter with no extra controls. The DA80 adds inline volume, mute, and call answer/end/hold controls, ideal for call centers. The DA90 works specifically with 6-pin "D" Digital headsets (model numbers ending in D) and supports fleet-level usage monitoring and management for larger deployments.
Can I connect an older Polaris-connector headset to my computer?
Yes, using the DA55 (basic) or DA60 (adds inline volume/mute, call controls, wideband audio, and echo management), both built specifically for Polaris-connector headsets.
Do I need new software to use a DA-series adapter?
It depends on the model — some older DA-series cables referenced the now-outdated PerSono software, since superseded by Poly's current device management tools. Confirm with our team which software, if any, applies to your specific adapter and deployment.
If you're expanding into unified communications without wanting to replace headsets you've already invested in, the DA-series lineup is exactly what bridges the gap — call our team at 877-999-3838 to find the right one for your deployment.
