Logitech H540 USB Computer Headset with Noise-Canceling Mic

Features

Noise Canceling Mic
Minimizes unwanted background noise for clear conversations. Right-sided mic can be conveniently positioned for better voice capture. Discreet boom can be tucked inside the headband and out of the way when you’re not using it.

High-Definition Sound Quality
Laser-tuned drivers and built-in equalizer provide rich, digital audio for full immersion in music, games and calls. This plug-and-play headset can be used with any PC or Mac computer with a USB-A port or adapter without the need to install software.

On-Ear Controls
Adjust the volume or mute your calls with simple on-ear controls located on the right ear cup. Confirm mute status with an easy-to-see light indicator on the headset cord.

Padded Comfort
Ultra-comfortable, adjustable design. Soft, padded leatherette headband and ear cups feel good even after hours of listening.

USB-A Connection
