I have no less than five Bluetooth headsets. Each does an ok job but one stands out. The Nuvelli wireless headphones. It has a large sound stage and beautiful highs, distinctive mids and a nice base. You will not be disappointed. The kicker is the charger plug for the ZIIO fits the headset and charges it. AMAZING! >> Stereo Bluetooth Headphone I should add that I run with these at the gym. They are prefect as they stay put.
