Duck, I am specifically talking about the Note 9, and if it may sound different, for whatever reason, from the V40. I am not talking about headphones alone. Obviously, a different pair of cans sounds different. I am only seeking to answer the question if there is any real reason why a BT signal from phone to phone would be impacted by any hardware. Whlle what I know would lead me to say no, various folks on the head fi forum have suggested as much. I am inclined toward the Note 9, but want to make sure I don't lose any audio quality in the process. That doesn't seem out of line to me.
BTW, I did have the Note version 1-5 (maybe 4), and they were not bad, but at the end of their cycle, they had awful battery life and worked like crap. My last 2 Lg's seem to be holding up better.
