‘MK I’ Armour Cable Headphones (ACC-40)


‘Mk I’ Armour Cable Headphones (ACC-40)

Product Description

What Are They?

Our ACC range of headphones are reliable, vandal resistant and suitable for any application within the public domain. The audio cable is protected inside a larger steel braided cable and we offer a Mk I and Mk II version. These are our MK I version and are are designed to offer commercial-use headphones at a cost effective price.


What’s different? Our MK II armoured cable headphones offer increased durability and improved sound due to the inclusion of the unique 90° swivel knuckle, a more robust anchor point between cable and headphones, as well as boasting an increased impedance of 100 Ohm. If you intend to use your headphones in a busy high use environment then we recommend the MKII, whilst the MKI are ideal for temporary exhibits or areas with less visitors.

What makes our Armour Cable headphones so exceptional?

blackbox-av originally developed the Armour Cable headphones for a contract with ‘Virgin‘ and ‘Our Price‘ in the early 90’s. With almost 20 years selling this popular product, we have developed the design to make the headphones as public-use ready as can be. We have recently taken the headphones in two directions, with the Mk I being our more cost effective option, and Mk II our premium more robust option.

How Do they Work?

Simply connect the Armour Cable headphones to your audio playback device, using the 3.5mm jack. If you are in need of an audio playback device we recommend our SoundClip range which contains an on-board amplifier and can output directly to 2 ACC headphones.
