Headphone jack is overrated. Keep the DAC as close to your ears as possible if you are an audiophile. For the rest of us casual listeners, the adapter is fairly cheap and just keep one connected to your headphones (or in the headphone bag if you got one).
I am willing to accept no headphone jack only if the device supports USB-C, like my new iPad Pro and every other product I have purchased in the last 4 years.
