It was not to make it waterproof as the LG V30 water rating is higher with the headphone jack. I am still using a 3 year old iPhone 6 Plus because of Apple dumping the headphone jack. Since the iPhone 3GS I had upgraded to a new iPhone every 1-2 years. I was going to switch to the Pixel 2 this year but Google also dumped the headphone jack even after making fun of Apple for doing it the year before (that and having to replace all of my purchased apps). In my quest for the best semi-portable sound possible I first bought a Beyer T-1 and paired it with an iFi iDSD Micro for the 6 Plus. It sounded excellent but was not the easiest to carry around. Then I bought a used pair of Shure SE846s and love them with no amp. I was about to upgrade to the LG V30 for the excellent audio but am now reading about some significant OLED screen issues. Sad that you must pay so much for a flagship phone and not get what people want/expect.
