Buy.com has the Parrot DRIVERHEADSET Plug-and-Play Bluetooth Headset Car Kit for only $24.99 with free shipping.

Product description from Buy.com:

At last a Bluetooth headset for drivers

The Parrot DRIVER HEADSET is a wireless headset that has been specially designed for all drivers keen on the headset concept, but who are confronted with the poor battery life offered by most of the models currently available.

Always charged and ready to go

!

The originality of the Parrot headset lies in its combined cradle that plugs into the 12 V cigar lighter. The cradle is used to both recharge and hold the headset when not in use. The long-life 90 mA battery is therefore always charged.

Hands-free headset kit

Once the kit has been paired with your Bluetooth phone, the cradle reacts to the slightest incoming call and notifies the driver by sounding a ringtone. Answer the call by pressing lightly on the headset to unclip it from the cradle: the call is established so chat away!

Ergonomic and effective

The Parrot headset has been specifically designed for in-car use and does away with the conventional headband and sidepiece, which tend to get in the way when driving. It fits naturally into the auditory canal. The headset weighs a mere 14 grams and offers 5 hours’ talk time on a full charge.

Compatible with all Bluetooth phones

The Parrot DRIVER HEADSET features a built-in Bluecore 3 p!
rocessor and offers complete compatibility with all the Bluetooth phon
es on the market.

FeaturesIn-car cradle doubles as headset carrier and charger when not in useRingtone and LEDs signals driver with incoming calls, headset easily unclips and call is connectedFeatures built-in Bluecore 3 processor for complete compatibility with all Bluetooth
