Quad DAC is not working properly

Quad DAC Settings showed High Impedence Audio device connected when I first plugged in my JBL headphones and that was awesome. It didn't change when plugged in second time and further. Any solutions ?
 
What is the impedence of your headphones? Without knowing that we can't know which of the two behaviours is correct.

(I'm assuming that the "problem" is that it is now treating them as low impedence; "it didn't change" is ambiguous, since coming after a statement that it showed high imedpence the first time it could imply that it did the same subsequently, though from the context I assume that isn't the case).
 
Looking around the web, most people reckon that the high impedance mode should be triggered when the impedance is > 50 ohms. Maybe you had a bad connection the first time and that made it think the headphone impedance was higher than it should be?

May be due improper connection. I'm not using the high end headphones.

AFAICT that's not a high impedance. The stock little earbuds that comes with my Oppo are 32ohms. High impedance in headphones I think would be around 100 ohms or more.

Are these JBL headphones stated as being high impedance? What model are they?

No it was not stating about those. It is not high end headsets. Headphone model is JBL T250SI
 
The headphone jack feels stiff on the V20's. Use a little more force and make sure the jack is fully seated. You wouldn't be the first or the last. I learned first hand.
