I have the companion 2 series computer speaker, and when i plugged my headphones into the headphone jack just below the volume dial, i was met with only left ear audio only. When i plugged my headphones into my interface directly, i didn't have that problem
Hi dracejr,
Thanks for reaching out. I am sorry to hear that you are having this experience.
Does this occur with all headphones you connect to your Companion 2 II speakers?
Can you inform us on what model your headphones are just to see if we can provide you any troubleshooting for this product?
