Plantronics DA80 USB Audio Processor
The Plantronics DA80 is an advanced USB audio processor engineered for professionals who demand broadcast-quality sound on every unified communications call. This compact external sound card replaces your computer’s built-in audio with studio-grade digital signal processing, delivering wideband HD voice clarity and active noise reduction.
Designed for Microsoft Teams, Zoom, and all major softphone platforms, the DA80 eliminates background noise and echo while optimizing your voice for maximum intelligibility. Whether you’re on back-to-back conference calls or hosting webinars, the DA80 ensures every word is heard with exceptional fidelity.
- Advanced DSP with active noise cancellation and echo reduction
- Wideband audio support up to 6.8 kHz for HD voice quality
- USB 2.0 connection with plug-and-play setup on Windows and Mac
- 3.5mm headset jack supports both stereo and mono headsets
- In-line call control with answer/end, mute, and volume buttons
Advanced DSP Technology for Crystal-Clear Calls

The DA80’s digital signal processor actively analyzes your audio stream in real time, applying intelligent filtering to suppress background office noise, keyboard clatter, and HVAC hum. This enterprise-grade DSP engine samples audio at 48 kHz and applies adaptive echo cancellation that eliminates feedback loops common with lower-quality USB adapters.
Wideband audio encoding extends frequency response from 150 Hz to 6.8 kHz, capturing vocal harmonics that standard narrowband codecs discard. The result is natural-sounding speech that preserves vocal tone and reduces listener fatigue during long conference calls. For professionals who spend hours daily on voice collaboration platforms, the difference in clarity is immediately audible.
Universal Compatibility & Setup

Our DA80 works as a plug-and-play USB audio device on Windows 7 and later, macOS 10.10+, and Chrome OS. The operating system recognizes the DA80 as a standard audio interface, so no proprietary drivers are required. You can hot-swap between computers without rebooting or reconfiguring softphone settings.
The 3.5mm headset port accepts any headset with a four-pole TRRS connector, including consumer earbuds and professional communication headsets. The DA80 automatically detects whether you’ve connected a stereo or mono headset and routes audio accordingly. In-line controls on the attached cable give you instant access to answer/end, mute, and volume without reaching for your keyboard.
Optimized for Unified Communications Platforms

Microsoft Teams, Zoom, Webex, and Skype for Business all support the DA80’s advanced audio features through native USB audio APIs. The processor reports wideband capability during call setup, allowing these platforms to negotiate HD voice codecs when both endpoints support them. Teams users can certify the DA80 through the admin portal to unlock one-touch meeting join on compatible headsets.
The DA80’s firmware includes pre-tuned EQ profiles for voice intelligibility, reducing the sibilance and plosives that often plague laptop microphones. Many users who previously relied on their computer’s internal audio find the upgrade to the Plantronics DA80 immediately improves how colleagues perceive their voice quality on calls. The same approach to audio clarity found in our DA70 adapter carries forward here with an expanded feature set and higher processing headroom for demanding workloads.

What people are saying

Common Questions About the DA80 Audio Processor
The DA80 works with any headset that has a 3.5mm four-pole TRRS plug, which includes most wired headsets. For wireless headsets, the DA80 is not the right solution—you would use the wireless headset’s own USB dongle or Bluetooth connection directly. The DA80 is designed to improve audio quality for wired headsets by replacing your computer’s built-in sound card.
The DA80 requires a USB Type-A port and is designed for use with Windows, macOS, and Chrome OS computers. It does not work with smartphones or tablets unless you use a powered USB OTG adapter, which is not officially supported. For mobile device audio, we recommend a headset with a direct mobile connection.
Both processors deliver wideband audio and noise reduction, but the DA80 offers higher processing headroom with a more advanced DSP chip that handles more aggressive noise environments. The DA80 also uses a premium aluminum housing versus the DA70’s plastic enclosure. If you work in a busy open office or need the best possible voice clarity for client-facing calls, the DA80 is worth the upgrade.
No drivers are required. Windows automatically recognizes the DA80 as a USB audio device and loads the appropriate class drivers. You can plug it in and start using it within seconds. The same plug-and-play experience applies to macOS and Chrome OS.
Yes, the DA80’s inline mute button functions as a hardware mute that works with Teams, Zoom, Webex, and other major softphone platforms. When you press mute on the DA80, the platform recognizes the mute state and updates the on-screen indicator accordingly. This gives you a physical mute button you can find by feel during calls.
Absolutely. The DA80’s DSP processing applies to all audio captured through the headset microphone, including recordings. Your recorded webinars will benefit from the same noise reduction and echo cancellation that improve live calls. Many customers specifically use the DA80 for content creation and podcast recording because of its consistent audio quality.
The USB cable is permanently attached to the DA80 and is not user-replaceable. The cable features reinforced Kevlar strain relief to prevent damage during normal use. If the cable does sustain damage during the two-year warranty period, contact our support team for warranty service options.
