Yamaha dgx 670 - jbl partybox 310 connection

[Adambalaton]

Hello!
I have a yamaha dgx 670 piano. I’d like connect it with jbl 310 soundbar, which has a “guitar” input. If I connect the piano from the headphone output, and put into jbl “guitar” input , will it be working?
Thank You!

The DGX headphone output will be stereo. I don't know anything about the inputs on the JBL, but guitars are mono, not stereo.

I see that the JBL also has AUX IN, which should be stereo, so you could get a 6.35mm-to-3.5mm stereo cable to connect them:
