This is the best price I've found on the internet for this particular headset. It's £20+ elsewhere. £14.99 at Play.com with free delivery.
It's compatible with most of the latest mobile phones, including the iPhone, iPhone 3G, BlackBerry, HTC, etc, and also compatible with the Sony Playstation 3!!
You can choose a stylish headset and still get the top capability you expect in a Sony Ericsson Bluetooth headset when you choose the HBH-PV708. Imagine how much you can get done while you talk on the phone for 15 hours, and with 500 hours standby, you'll rarely need to recharge your PV708. Make your life a little bit less of a juggling act. The PV708 keeps you on top of your calls in the car, at home or anywhere your busy day takes you. Bluetooth Headset HBH-PV708 is compatible with all the Sony Ericsson and non-Sony Ericsson mobile phones.
