Easy All-Day Comfort: This headset is made to be comfortable for all-day use. Compared with binaural Bluetooth headsets, this single ear Bluetooth headset is lighter and allows you to hear what's going on around you and not break any laws while driving. If interrupted, you can deal with issues and move on quickly instead of removing your headset. It also won't make regulating your voice volume difficult. The mic is 270°rotatable to fit either ear. The hinge can rotate to fit the shape of your head. The adjustable slide does a great job of shaping the headset to the size and form of your head. Ultra-soft memory foam earpad makes the laptop headset extremely comfortable for the whole day.
