I'm pretty sure you can increase the quality of the DAC if you purchase two additional dongles and create the following configuration:
(iPhone)+(male lightning)(cord)(female 3.5mm)+(male 3.5mm)(cord)(female lightning)+(male lightning)(cord)(female 3.5mm)
This logic is fairly irrefutable, and it will most likely increase the DAC quality three fold, if not much more. You can add additional dongles if you want, but it's a bit overkill at that point. Science dictates that three dongles is the optimal number of dongles to dangle from your device.
I don't really understand why anyone is complaining. This will provide an extended headphone cord and make the user appear as if they are a technological wizard. If you don't like the appearance of the configuration, I'm sure you can find some common material at Jo-Ann Fabric, such as chainmail, to create an aesthetically pleasing cover that is both functional and protective.
