Is the sound loud enough to cancel the outside noises ?
How do you charge it ?
In a very loud environment you ll gonna have a problem with any bone conduction headphone out there. So there is no cancel whatsoever because the purpose of these headphones is to have auditory contact with the environment while you listening to music. It can be charge via any usb port.
