A20 works for Rotorcraft and Fixedwing now

  • By Richard from Smyrna GA USA on Monday, September 17, 2018
  • Pros: I didn't have to buy a new headset
  • Review: I had the fixed wing straight cord and wanted the rotorcraft 'coil' cord. Not hard to switch depending on what aircraft I'm flying. Didn't want to use a non coil line in the helicopter. And wanted a straight line for fixed wing. I just have to carry a small Philips head with me in a case with the other cord.

    Q: Does this device have low or high impedance rating? I purchased a headset/ controller mic combo, but it doesn't work on fighter jets. Has a galaga style chirp when connected to the intercommunications and hotmic turned on, but can receive audio signals without problems.

    A: This is high impedance for civilian helicopters.  For military aircraft, you would generally need the Bose A20 Cable Assembly NO Bluetooth - Straight Cord for MILITARY 5-ohm mic

    Q: Can you play music through Bluetooth ? I have a Bose A20 with bluetooth but the Bluetooth only works for phones calls I’m not able to play music through Bluetooth Will this cord work give me the ability to play music through bluetooth ?

    A: Yes, this supports streaming music over Bluetooth.  Cables made before 2016 did not support stream Bluetooth but all cables after 2016 work great.
