Headset is used in most cases of a hands free device. Wired and unwired are the two types of headsets available. Bluetooth technology is used in case of unwired headsets in order to transmit signals between headset and the phone.
In some phones there is an in-built hands free device and no special equipment is required in this case. By using a speaker phone, the process of hands free is achieved. Although there is no need to hold the phone but one should be close enough to the phone so that clear voice transmission can be achieved.

So, if one loses it then its replacement cost is near about $10 to $30 US Dollars (USD). But for wireless hands free device the price may range from $20 USD to even more than $100 USD as it depends on the features and the brand involved.
