Pinout for Harman Kardon BT Bluetooth Headphones Charger Cable

I just got this headset and really love it. I'll probably lose the somewhat non-propriety charger cable, which uses a standard USB A connector on one end and a 2.5" 4-pin audio connector jack on the other. So, here's the pin diagram.


  1. Just bought one of these. They're awesome. And with this no-standard charger i was thinking the same as you. Thank you for the diagram.

  2. This is awesome, was regretting check wiring with my multimeter on this cable before I lost mine months ago. Thanks for the info!

  3. Gracias por este excelente Diagram estuve buscando el cable y no apareciĆ³,ahora gracias a Usted por su gran aporte!! saludos desde Repucblica Dominicana

  4. I've left my cable in hotel. Thank's form Poland...

  5. Quite old topic but cannot find out such info on internet..
    Do you think is the same wiring for JBL wireless headphones?

    1. There's a good probability that it's the same. JBL and Harman Kardon are the same company. I'd try it first for a few seconds, keeping my eyes, ears and nose open in case anything goes awry. If the charging light turns on you should be fine.
