NC-4
These Ambient Noise Cancelling Headphones cancel background noise such as fan noise from computers and printers. They do this by inverting the ambient noise to cancel it out. They are supplied with an aircraft audio adaptor so you can listen to films or cd without the jet engine noise whilst travelling on an aircraft. Powered by AAA battery, the noise cancelling can be switched off if not required.
