A:AnswerYes, it is just slightly longer than 3 inches. It appears to be the exact same item that was included with my iPhone 7 - but of course, this one was purchased separately.
A:AnswerI have an iPhone 11 and it works on that. The dongle is only 3 inches long. If the charge connector on your phone is the same as an 11 it will work. I use the dongle to attach a Pop phone to my iPhone.
A:AnswerNo, you cannot use this with an external DAC. This product is an analog output for traditional headphones. It has a built in DAC and amp (the same chips used by Apple in earbuds). To use an external DAC use the lightning to USB cable that comes with the phone. The DAC may give an error because it requires more power. In that case you need to get a powered USB hub (iPhone to hub to DAC). Those can be found on Amazon for under $20.
A:AnswerI plug regular aux skullcandy ear buds into this adapter, assuming you are also using an iPhone like me, since they don't have the commonly accepted ports
A:AnswerYes. Apple has supported audio over lightning cables for a long time, even when they still had headphone jacks. I have an older iPad Pro and it works fine with it (just don’t need it).
