The Honeywell Airlite 700 Wireless Bluetooth Headset performs admirable well. If you require wireless Bluetooth headset that has great range, battery life and speaker/mic clarity I would recommend you check this product out. Also, it's only .57 x 0.44 x 0.70 (inches) in size and weights 9 grams (.32oz). Small and lightweight is key for a mobile phone headset because over time a heavy headset would become a burden.
