Plantronics EncorePro 520 Over-the-Head Wired Headset
The EncorePro 520 is engineered for professionals who spend hours on the phone every day. Built with our proprietary audio technology and reinforced steel headband, this over-the-head wired headset delivers exceptional voice clarity while standing up to the rigors of high-volume contact center environments.
Whether you’re managing customer calls, conducting virtual meetings, or coordinating with remote teams, the EncorePro 520 ensures every conversation is clear, comfortable, and productive. Our noise-canceling microphone filters out ambient distractions so your voice comes through crisp and professional on every call.
What makes the EncorePro 520 unique
Audio performance & noise cancellation
The Plantronics EncorePro 520 features our ultra wideband audio technology, delivering frequency response from 150 Hz to 6800 Hz for natural, lifelike voice reproduction. You’ll hear every nuance of customer conversations without the tinny, compressed sound common in standard telephony headsets.
Our noise-canceling microphone uses advanced acoustic foam and positioning to capture your voice while rejecting up to 85% of background noise. In busy call center environments where dozens of agents work side by side, this means your customers hear you clearly without the distraction of neighboring conversations, ringing phones, or office equipment. The microphone boom rotates 300 degrees and locks into your preferred position, ensuring consistent audio pickup throughout your shift.
Built for durability in demanding environments
Contact centers and high-volume office environments demand equipment that can withstand constant daily use. The EncorePro 520 headband is constructed from reinforced steel, tested and rated for more than 50,000 bends without losing tension or breaking. Metal pivot joints replace the plastic hinges found in consumer-grade headsets, providing years of reliable service.
The flexible microphone boom resists the wear and tear of hundreds of positioning adjustments per week. Soft leatherette ear cushions are replaceable, extending the headset’s usable life and maintaining hygiene standards in shared-headset environments. Every component is engineered with repairability and longevity in mind, reducing total cost of ownership for large deployments.
Comfort engineered for extended wear
At just 78 grams, the EncorePro 520 is one of the lightest professional binaural headsets available. The over-the-head design distributes weight evenly across your head rather than relying on a single ear, reducing fatigue during 8-hour shifts or marathon conference calls.
We designed the leatherette ear cushions with ventilation channels to promote air circulation and reduce heat buildup. The cushions are generously padded to create a gentle seal without clamping pressure, and they’re soft enough to accommodate eyeglasses comfortably. The adjustable headband features multiple size settings with clear click-stops, so each user can dial in their perfect fit and return to it instantly when sharing equipment across shifts.

Common questions about the EncorePro 520
The EncorePro 520 uses a Quick Disconnect connector that works with bottom cables for all major desk phone systems. We offer QD cables specifically designed for Cisco 7900 and 8900 series, Avaya 1600, 9600, and J100 series, Polycom VVX models, Yealink T4 series, and many others.
When ordering, select the bottom cable that matches your phone model. If you’re unsure which cable you need, contact our support team with your phone model number and we’ll recommend the correct configuration.
The primary difference is wearing style. The EncorePro 520 is binaural with cushions covering both ears, providing better noise isolation and immersive audio for high-concentration work. The EncorePro 510 monaural design covers one ear, allowing you to hear your surroundings while still benefiting from professional call quality.
Both models share the same reinforced steel headband, noise-canceling microphone, and ultra wideband audio technology. Choose binaural if you need maximum focus and noise rejection, or monaural if you require environmental awareness for safety or collaboration.
Yes, by pairing the headset with our DA series USB adapter or any compatible QD-to-USB cable. The Quick Disconnect design allows you to swap bottom cables without replacing the entire headset, so you can move between desk phone and computer applications as needed.
For the best softphone experience, we recommend the DA90 USB audio processor, which adds inline call controls, mute functionality, and enhanced audio processing optimized for platforms like Microsoft Teams, Zoom, and Cisco Webex.
Cushion lifespan depends on usage intensity and environment, but most users report 12 to 18 months of daily use before noticing reduced comfort or visible wear. In shared-headset environments or high-humidity climates, you may want to replace cushions every 9 to 12 months to maintain hygiene and acoustic seal.
Replacement leatherette cushions are available as a two-pack accessory and install in seconds without tools. Keeping spare cushions on hand minimizes downtime and ensures your team always has fresh, comfortable equipment.
Every EncorePro 520 is covered by our standard two-year manufacturer warranty against defects in materials and workmanship. This includes the headset, boom, headband, and ear cushions under normal use conditions.
The warranty does not cover wear items like cushions that degrade naturally over time, or damage caused by misuse, accidents, or unauthorized modifications. Extended warranty and advance replacement programs are available for enterprise deployments requiring guaranteed uptime.
Yes, the EncorePro 520 headband features a multi-position adjustment mechanism with clear click-stops for sizing. The range accommodates head sizes from small to extra large, and the steel construction maintains tension settings without stretching or loosening over time.
Each user can quickly dial in their preferred fit and return to it reliably when headsets are shared across shifts. The leatherette cushions also rotate slightly to conform to individual ear angles for a customized seal.
No, the EncorePro 520 is a fully passive wired headset that draws all necessary power through the QD bottom cable connected to your phone or USB adapter. There are no batteries to charge or replace, and no separate power supply required.
The noise-canceling technology uses acoustic design and foam positioning rather than active electronic processing, so it works reliably without any additional components or maintenance. Just plug in and start your calls.
