PLT Blackwire 5220 USB-C Wired Headset 3.5mm 32 ohm 138g

All-Day Wired Headset for Calls

The PLT Blackwire 5220 is a wired over-ear headset built for professionals who spend long hours on conferences. It connects through USB-C with a tethered USB-A adapter or a 3.5 mm jack for mobile devices. Certified for Microsoft Teams and Zoom, it targets home-office workers who need simple plug-and-play audio without wireless pairing steps. Buyers wanting Bluetooth freedom or active noise cancellation will not find those features here.

Passive Isolation and Fixed Audio Specs

Passive noise isolation comes from the conforming ear cushions rather than active circuitry, so constant low-frequency hum is reduced but not eliminated. The dynamic driver runs at 32 ohms with a 20 Hz to 10 KHz frequency response, while the flexible boom microphone covers 80 Hz to 10 KHz. Both transducer and microphone share a signal-to-noise ratio and sensitivity of 11 decibels, giving a predictable baseline for voice clarity in typical office backgrounds.

Lightweight Build with Multi-Device Wiring

At 138 grams the headset adds minimal load during extended sessions, and the retractable boom mic tucks away when not in use. Inline call controls handle answer, end and volume without reaching for software. The single USB-C cable includes the integrated USB-A adapter, so one cord serves both modern and legacy ports, while the 3.5 mm connection frees the USB port entirely for phone or tablet calls. No separate power supply or driver installation is required.
