To anyone who has their devices so far, how would you rate the audio quality, specifically through good quality, high impedance (50+ ohms) headphones? I ask because I listen to my music library a lot, and having owned the LG V30 for about a month, the quad DAC definitely makes a huge difference to the listening experience. While I loved it and the battery life, LG's UI leaves a lot to be desired, both aesthetically and feature-wise. I don't expect headphone audio on the Note 9 to best the V-series, but if it's at least comparable, along with the reports of good battery life so far, the Note 9 will be the upgrade to my Nexus 6P. Thoughts, anyone?
