Comfort counts
Similar in design to , the M120 features a hard plastic earpiece that rests on top of your ear and is arguably a tad less comfortable than the M130's foam padded earpiece. That said, the unit slips on and off easily and is fairly light and secure. In fact, we found it more secure than Jabra's EarWrap.
As for features, the M120 has a mike adjustment switch but not the in-line volume control found on the step-up . Unfortunately, it doesn't have an Answer/End button.
A sound buy
We have no complaints in the audio department. Callers sounded loud and clear and said they didn't have any trouble hearing us, except in windy conditions.
