Mini piano 201 headphone hack?

Hi there! Just got myself a 201 and wondering if there’s some way to rig some headphones up to it either using the usb or line out port. Thanks in advance!

I use one of these 1/4” Mono to 1/8” Stereo adapters:

Disino 1/4 Mono to 3.5mm Stereo Adapter, Gold Plated 6.35mm TS Male Plug to 1/8 inch TRS Female Audio Connector - 2 Pack

awesome thanks! I’ll try that out, much appreciated
