Our Price 130.80 (109.00 ex. VAT)

The Classic HM40 Headset is back!!

This headset since its introduction has grown to be very popular with flying schools, private pilots and other users in high noise environments. This popularity is due to its superb passive noise reduction capabilities and strong construction whilst only weighing 16 oz. It has an electret noise cancelling microphone mounted on a flexible 'rubber duck' boom. The earseals are liquid filled to affect a close fit and the headband is air foam filled. The cable is of a reinforced construction and the headset is supplied with microphone sock and cloth ear covers.
