Is it possible that headphones could possibly open or weaken that barrier? Of course it would be a much weaker effect as the sound frequency is different.

  No. Or at least as far as we know. Ultrasound is still a mechanical force that can be focussed in a specific area to open a part of the Blood Brain Barrier. Wifi and bluetooth are electromagnetic, and interact less with the brain. Their transmission power is also extremely low. So they don’t do much. Super powerful MRI scanners (3T or more) can heat up the body a little bit with electromagnetic waves, but still no focal damage or anything. Trauma however, or certain diseases can open the barrier.

    I think they were asking about acoustic vibrations generated from wearing headphones, rather than EM radiation?

      That was my reading too.
