The TELEX AIRMAN 850 is a wired headset with a boom microphone and over-ear leather ear pads. - Model Name: TELEX AIRMAN 850 - Connection Type: Wired 2-pin - Ear Pad Material: Leather - Microphone Type: Boom Microphone - Noise Canceling: Yes Thank you for viewing. I used this when boarding a small propeller plane. Because it has a noise-canceling function, the noise from the propeller is considerably reduced. Also, it is lighter than other manufacturers such as BOSE, so there is less stress from wearing it.
