Plantronics C054 Wireless Headset
The Plantronics C054 brings enterprise-grade wireless freedom to your desk phone or softphone setup. Built on DECT 6.0 technology, this over-the-ear headset delivers interference-free audio across a 350-foot range, so you can move around the office without dropping calls.
We engineered the C054 with all-day wearers in mind. The cushioned earpad distributes pressure evenly, while the adjustable headband lets you dial in the perfect fit. A noise-canceling microphone filters out keyboard clicks and background chatter, keeping your voice front and center on every call.
Whether you’re managing a high call volume or coordinating remote teams, the C054 handles 12 hours of talk time on a single charge. The magnetic charging cradle snaps the headset into place at the end of the day, so it’s always ready when you are.

DECT 6.0 wireless clarity
The Plantronics C054 runs on DECT 6.0, the same secure frequency standard used in cordless home phones. Unlike Bluetooth headsets that share the crowded 2.4 GHz band with Wi-Fi routers and microwaves, DECT operates at 1.9 GHz — a dedicated slice of spectrum that stays clear of interference.
You get consistent call quality whether you’re standing next to the base or walking 350 feet away to the break room. The digital signal encrypts your conversation automatically, so sensitive client calls stay private. We’ve tested the C054 in open-plan offices with dozens of wireless devices running simultaneously, and audioDropOff remains virtually nonexistent.
All-day wearing comfort
We built the C054 around a single-ear design that balances call clarity with environmental awareness. The memory foam ear cushion molds to your ear’s contours, and the adjustable headband slides up or down to distribute weight evenly across the top of your head.
Weight Distribution
At just 3.2 ounces, the headset disappears during long calls. The rotating boom arm lets you position the microphone on either your left or right side, and the flexible boom stays exactly where you set it — no constant readjustment mid-conversation.
Battery performance and charging
A full charge delivers 12 hours of continuous talk time, enough to cover back-to-back calls from morning standup to end-of-day wrap. Standby time stretches to 100 hours when the headset is docked but powered on, so you can leave it ready between calls without draining the battery overnight.
The magnetic charging cradle pulls double duty as a desktop stand. Drop the headset onto the cradle at any angle, and the magnets guide it into alignment. An LED ring glows amber during charging and switches to green when the battery hits 100 percent, giving you a quick visual check without opening software.

Common questions about the C054
