Bose A20 Aviation Headset Control Module Holder

Various on-board holders for Bose A20 Control Modules. The modules fit in perfectly and are aligned with the top layer of the holder for optimal accessibility of the keys and volume knobs. Also fits for the Bluetooth Version.

Fix in a suitable place with adhesive tape as desired (e.g. with Tesa Powerbond) to keep the battery modules sorted and easy to access. No more in-flight struggling about which is your controller.

Rectangular single and double versions provided for general purpose use. A slanted and an ergonomically rounded, slim version have been added for aircraft with limited space (e.g. for the DA40).
