Plantronics M50 Bluetooth Headset
Disadvantages
- omnidirectional microphone transmits all external noise, therefore less suitable for use in the car
- the voice control of the smartphone does not always work satisfactorily with loud background noises (escalator, station announcements etc.)
- microphone mute is fiddly because the tiny volume buttons [+][-] have to be pressed simultaneously and are too close together
