Well, a headset or an earbud is a personal choice depending on the individual’s comfort level. While many people do not like to go with a headset if it has to be worn for several hours, whereas, many are not comfortable with the earbuds for their in-ear design that goes into the ear canal. It is, however, recommended to go for an over-ear headphone as it is the most comfortable option if you need to be on call most of the time of your work.
