We designed the C052 with all-day wearability in mind. The ultra-lightweight frame weighs just 21 grams, while soft leatherette ear cushions and an adjustable headband ensure comfort during extended conference calls and customer interactions.

DECT 6.0 wireless connectivity & range
The Plantronics C052 uses DECT 6.0 wireless protocol, operating on the 1.9 GHz frequency band to eliminate interference from Wi-Fi networks, Bluetooth devices, and other common office electronics. This dedicated frequency ensures your calls remain private and clear, even in crowded workspaces with dozens of active wireless devices.
With an operating range of up to 350 feet, you can step away from your desk to retrieve files, consult with colleagues, or move to a quieter area without ending the call. The included charging base doubles as the wireless transmitter and docking station, requiring just a single power outlet and one desk phone connection. Pairing happens automatically when you dock the headset, so there’s no complicated setup process or button sequences to memorize.
All-day comfort & ergonomic design
We engineered the C052 with a focus on extended wear comfort. At just 21 grams, the headset applies minimal pressure across the head, reducing fatigue during marathon call sessions. The leatherette ear cushion conforms to your ear shape while remaining breathable, preventing the heat buildup common with foam-only designs.
The adjustable padded headband distributes weight evenly and accommodates a wide range of head sizes without creating pressure points. Unlike rigid over-the-head designs, our flexible frame maintains a secure fit whether you’re seated at your desk or walking through the office. The rotating microphone boom allows you to position the mic on either your left or right side, and it stays exactly where you set it without drifting during the workday.
Audio quality & noise-canceling microphone
Wideband audio support delivers frequencies up to 6800 Hz, capturing the full tonal range of human speech for natural-sounding conversations. Dynamic EQ adjusts bass and treble response based on whether you’re listening to voice or multimedia content, optimizing clarity without manual intervention.
The noise-canceling microphone filters out keyboard typing, office chatter, and HVAC hum before it reaches the caller on the other end. We tested the C052 in open-plan offices with ambient noise levels around 65 dB and found the microphone consistently isolated the speaker’s voice while suppressing background sources. SoundGuard technology also protects your hearing by limiting sudden loud sounds to safe levels, meeting acoustic safety standards for all-day professional use.

What people are saying
Common questions about the Plantronics C052
The C052 provides up to 350 feet of wireless range from the base station in open office environments. Actual range depends on physical barriers like walls and metal partitions. In typical office layouts with cubicles and interior walls, most users can move freely throughout a 3000-4000 square foot area without signal loss.
The Plantronics C052 connects via standard RJ-9 headset jack, compatible with most business desk phones from Cisco, Avaya, Polycom, Yealink, Mitel, NEC, and other major brands. If your phone lacks a dedicated headset port, you can use an optional electronic hook switch cable for remote call control. Check your phone’s user manual or contact our support team to confirm compatibility for your specific model.
The C052 delivers up to 13 hours of continuous talk time and up to 50 hours of standby time on a full charge. Charging the headset from empty to full capacity takes approximately 3 hours when docked in the base station. The headset provides a voice alert 10 minutes before the battery runs out, giving you time to wrap up calls or dock for charging.
Yes, the microphone boom rotates 180 degrees, allowing you to wear the C052 on your left or right ear. The boom holds its position once adjusted and does not require re-positioning throughout the day. The single-ear design lets you stay aware of your office environment while remaining fully engaged in phone conversations.
The C052 is designed specifically for desk phone use via DECT 6.0 wireless and RJ-9 connection. It does not support Bluetooth or USB connectivity for computers and mobile devices. If you need multi-device connectivity, our Savi W740 or Voyager Focus UC models offer desk phone, PC, and mobile connectivity in a single headset.
The C052’s noise-canceling microphone is engineered to filter out ambient office sounds including keyboard typing, nearby conversations, and HVAC noise. It focuses on your voice while suppressing background sources, ensuring callers hear you clearly even in open-plan environments. For contact center use or extremely high-noise settings, binaural models like the EncorePro series may provide additional passive noise isolation.
Each C052 package includes the wireless headset, charging base with integrated DECT transmitter, AC power adapter, desk phone connection cable with RJ-9 connector, and quick-start guide. The leatherette ear cushion and padded headband are pre-installed. Optional accessories like replacement cushions and electronic hook switch cables are sold separately.
