U384 to XLR5 plug
 

Hi, I bought a bose A20 with U384 plug, and I buy from nexus u384/u to xlr5, but I set the xlr5 pin configuration
XLR-5 pinout:
Pin1 - Ear+
Pin2 - Ear-
Pin3 - Mic +
Pin4 - Mic -
Pin5 - No connect
With this configuration works only the mic, but earphones eater one not working, I use for the U384 this configuration
U-385/U jack.

Wiring Configuration:

Civilian Stereo:
Microphone High to Pin 1
Microphone Low to Pin 2
Earphone Left High to Pin 3
Earphone Right High to Pin 4
Earphones Low to Pin 5
Please help me what I'm doing wrong, thanks.

Mate, just but the A20 XLR5 pin section. you attach it to the joint on the headset cup and job done. The proper one gives power (you still need batteries but they last forever) Far better than messing about trying to wire your own.

The Genuine Bose part also is ISO approved, whereas your DIY setup is not!

Connect Left and Right Earphone high to Pin1 on XLR5
Connect Earphone Low to Pin 2 on XLR5

Thanks, I will set this configuration hope this work, greetings
