Lenovo 4XD1S19778 Dual Mode Wireless ANC Headset 6550

Overview

The Lenovo 4XD1S19778 is a premium wireless headset engineered for high-performance communication in open-office and hybrid work environments. Certified for Microsoft Teams Open Office, it ensures seamless integration and hardware-level control for Teams meetings. This model features Hybrid Active Noise Cancellation (ANC) with three distinct modes to filter out ambient noise, allowing users to maintain focus in busy settings. On the transmission side, it utilizes AI-powered Environmental Noise Cancellation (ENC) across a 5-microphone array to eliminate up to 99% of background noise, ensuring professional-grade voice clarity.

This "USB-C" version is identical in performance to the 19777 but includes a dedicated USB-C Bluetooth audio receiver, making it the ideal choice for modern laptops and workstations that have transitioned away from USB-A ports. It supports Bluetooth 5.3 with Multipoint technology, enabling stable, simultaneous connections to a PC and a smartphone. The headset is SGS-certified for ergonomic comfort, featuring a pressure-relieving headband, premium leatherette memory foam earcups, and 135-degree swivel functionality.

Power management is a core strength, delivering up to 60 hours of playback or 30 hours of talk time on a single charge. It includes several intelligent workflow features, such as a 360-degree "busy light" to prevent interruptions and a flip-to-mute boom microphone that can be worn on either the left or right side. Compatible with Lenovo's LADM and LAFM software, it allows for centralized firmware updates and personalized audio tuning, backed by a 3-year limited warranty.
