The Duke cell phones are back in the news.
A group of people in the US are suing the Duke for using the device to spy on their cell phone calls.
The suit says the earpieces were not meant to spy but were used for spying on the calls of others and for obtaining information about them, as well as monitoring the phones activities and location.
The earpieces can also collect location information, which is then used to track the location of the cell phone.
The Duke is being represented by a New York firm.
