I'm thinking about purchasing an external Dac for my iPhone to improve volume and quality of music I listen to when out and about.
I understand when I upgrade from the 6 to the iPhone 7, I will be forced to use an external Dac if I want to keep the same headphones I'm using now? Betron B750s.
Any Dac recommendations? I don't want something which drains the iPhones battery.
Been looking at Dragonfly black/reds, anyone using one of these?
