I was under the impression that only beats branded headphones would allow the beats audio enhancement feature on the rezound. I plugged my car audio in and it allowed beats, and now listening with a pair of ableplanet headphones it also allows beats. I could swear that I've used other headphones and it didn't give me the option. Was there an update that allowed all headphones to have this feature? It's not a bad thing, I'm just curious.
