My cowin E7 headphone doesn't show any blue light for connectivity and headphones are not shown in my paired devices and available connections and I didn't hear any beep sounds after I press the button.

Was this working for a while before or is the device new ? What are you pairing it to by the way ?

So just to check, what lights at all does it show at what points when trying to turn it on and when charging?

The headphones are showing only the white 'noise cancellation' light. It doesn't show any blue light blinking.

And you are sure they aren't paired to anything else nearby? And you are sure the switch is still set to BT on the side?
Finally, if you have no joy, resetting by holding down the plus and minus volume buttons together for 5/6 seconds doesn't do anything ?
