PPLICATIONS

The HS 400 is a closed-back aviation headset. The headphone features a very high reproduction precision and a balanced sound.

Another special feature is the wide frequency response of

5 - 30,000 Hz.

The soft, circumaural ear pads filled with viscoelastic foam and the adjustable padded headband provide a high comfort. The microphone with adjustable gain can be optimally positioned with the flexible gooseneck. The figure eight polar pattern ensures a high gain before feedback and noise cancellation. The rotating microphone holder allows positioning the microphone on the right or left hand side.

The connecting cable is single-sided. There are various versions with different connecting cables (e.g. 1/4" (6.35 mm) and PJ-068 jack or

U-174/U jack). The connecting cable provides an audio box to adjust the volume of the headphone and to connect a mobile phone or music player (e.g. CD or MP3 player). If signals from the intercom occur, the volume of the mobile phone or music player can be reduced automatically. This function can also be switched off.
