I amplified Quest 2 audio with cordless over-ear headphones that were turned off

I would like to share with you a pleasant experiment which in my case was successful and I was happy.
While wearing my Quest 2 I tried cupping my hands tightly around my ears.
I noticed a greater sensation of isolation from the outside (but okay) and consequently less dispersion of the audio produced by the stock speakers.
I have a pair of over ear headphones, Beats Studio which fortunately have a detachable cable.
It will obviously work with all over-ear headphones that have good insulation from the outside.
I just put them on making sure they covered my ears and lined up with the speakers on my Quest 2. I didn't turn them on, plugged them in and the effect was as desired.
Now I can avoid using wired headphones (less annoyance) and bluetooth headphones avoiding potential interference with wifi and less power consumption.
