The Logitech H820e is a comfortable, user-friendly and wireless headset with a range of up to 100 meters. You can get up during a long telephone conversation, take a walk or get a cup of coffee. When the headset is fully charged, you are assured of approximately 10 hours of talk time. The lightweight design, padded headband and premium materials such as TR90 nylon mean you can wear this headset for hours on end. The LED light on the microphone lets you know you're on a call so you won't be disturbed. Thanks to the noise-canceling microphone, you won't be bothered by ambient noise and you can enjoy crystal-clear sound. The integrated buttons on the earpiece allow you to answer, end and change the volume.
