The article you mention (2) does not appear to say that it "does away with a DAC". Rather, it correctly states that by using a digital interface the user has choice to select their own DAC, built into the headphones. Users can of course use any USB headset with a USB adapter if they want. The other article, which you use to support the fact that the external audio is lower quality states "the bottom line is that the difference is going to be completely imperceptible to most people.". And of course, other options than Apple's included headphone adapter are available, which maybe higher quality. There are many valid reasons why you might not like the iPhone, or might want a headphone jack. However the reasons you've provided don't seem valid to me, unless I've misunderstood something.

> The 3.5mm port is an analog output on the phone. The lightning port is a digital output. Needless to say, all the circuitry in the phone is digital. So accommodating analog technology isn’t ideal. >By taking out the 3.5mm jack, Apple is removing the need for these two components. The lightning port and lightning input are both digital, so the phone does not need a DAC any more. The iPhone 7 can thus be more battery efficient, and have room for other components (like a bigger battery) in its slim case. These arguments are deluded. The phone might not need a DAC anymore (hang on, I guess it does for the built in speakers), but the user does. It doesn't help with battery efficiency unless the DAC is powered separately, in which case you have two things to charge. Room for other components? Well if you want a bigger battery why don't you just have an extra one attached to a dongle to charge the phone up with? Why not remove the screen, another digital to analog device, to save space and battery, and just have an HDMI out? I know these are silly examples, but a phone brings convenience - it's convenient if a phone can last all day on one charge, and also convenient if it can interface with headphones. Stepping back a bit, these articles seem to crop up periodically - I remember similar about the lack of GPS in the first model, the problems with the 4's antennae etc. Getting a bit philosophical here, but I wonder if the same people who refuse to accept valid criticisms of an Apple product also believe in 'good' and 'bad' people who can either do no bad or do no good. Google translation of the original German page is fairly clear: > With the saving of the jack socket, Apple deteriorates the output quality of the music on the iPhone. While the output sockets of the iPhone 6S and iPad Air itself perform well in comparison with professional audio interfaces, the output on the new Lightning adapter of the iPhone 7 and 7 Plus reaches only the note satisfactorily. >The differences should be noticeable in comparison with similar connected headphones in the price class from 100 euros, especially with uncompressed music files with 24 bit. In the case of lossy compressed music pieces (MP3, AAC), however, most users hardly notice a difference. Bluetooth headphones and digital audio interfaces are not affected by the deterioration. A 4.5dB loss is actually pretty big.
