Don't want to ding the product - I was the one who took a chance at the cheap price, and found ti failed to work with a 6650 (I can hear, but the mike isn't connected! I guess I need a different sequence of ring/metal components on the plug).I'm all Bluetooth now, and the marginal cost on buying this wired adapter to try on an existing shipping-paid order was low, so no huge loss.Looks very well built. May work with other Nokia phones, just not the 6650.
