Cringe worthy and very pathetic to mock a phone that hasn't been released yet.
I reckon in a few years time more manufacturers (Samsung included) will remove the 3.5mm headphone port and use the USB Type C, and then advertise the fact of the better audio quality by using this.
If Apple do remove the 3.5mm port (which I think they will) they are going to respond to criticism with the argument of improved audio quality but not using the 3.5mm port. Definitely going to be a controversial move, removing the 3.5mm port though.
The quality of audio produced from the digital data transmitted via lightning port will not improve after 3.5mm jack is removed. It'll stay exactly the same and will depend on the quality of the external DAC and amplifier (as it always was)
