This silver colour Universal ICON BT4517T Bluetooth Headset Includes Charger has an earhook design. It also features a 10m operating range, up to 50 hours standby time and up to 8 hours talk time. This headset also includes LED indicators, last number redial, in-car charger, and answer or end call button.
Not available online but there were loads at my local Extra store. Cheapest bluetooth headset I have found, I bought mine as a spare set! I bought the black set. The spec is wrong on the website...I DOES come with a charger and it uses V2 Bluetooth and has voice dialing!
