The Lenovo Dual-Mode Wireless ANC Headset 6550 is a professional audio solution designed for open office environments, featuring Microsoft Teams certification to ensure seamless communication. It utilizes Bluetooth 5.3 and a USB-A wireless receiver to provide a stable connection within a range of up to 30 meters, while multipoint connectivity allows you to stay linked to multiple devices simultaneously. The hybrid active noise cancelling system offers three distinct modes to help you focus by filtering out ambient sounds, complemented by a built-in rotatable boom microphone that uses AI environmental noise cancellation to keep your voice clear during calls. Constructed from lightweight plastic, the headset weighs only 165 g and features an adjustable headband with 135° flexible swivel earcups. This design, combined with SGS Comfort Certification for pressure relief, makes it suitable for long workdays without causing fatigue. The closed-back, on-ear style ensures a secure fit, while the microphone can be switched to either side of the head and flipped down to quickly answer calls or unmute your audio. With a 640 mAh battery, you can enjoy up to 60 hours of playback or 30 hours of talk time, and a full recharge via the USB Type-C port takes less than two hours. The device supports a frequency response of 20 Hz to 20,000 Hz with 32 Ohm impedance, and it complies with international hearing protection standards like EN50332. For those who prefer a tailored sound, the LADM software allows for audio customization, making this a versatile tool for professionals who spend significant time in virtual meetings.
