Plantronics M100 Bluetooth Headset - Charcoal GrayProduct Review (submitted on January 30, 2013):
This headset works very well and the price is impossible to top. The only negative is that using for a prolonged period leaves my ear a bit sore since the headset bud fits into my ear. Perhaps those with larger ears wouldn't have this issue. However, overall I am very satisifed with this headset and would purchase it again.
