That would have been good to include with your original post.
I provided instructions for pairing a Sony wireless Bluetooth headset which should not be radically different or different at all between different Sony wireless Bluetooth headset models. It makes no difference if the little lights on yours are a different color from those included with the instructions, and if yours does not include a power button, it is not a wireless Bluetooth headset.
If the packaging does not include instructions for pairing the headset via Bluetooth, more than likely it is not a Bluetooth headset. If a Bluetooth headset, it would include a power button and the instructions provided for pairing a Sony wireless Bluetooth headset would apply regardless the model, CAPISH dip-****?
