Setup and management are very easy. the biggest issue ive had with Apple branded earbuds is that theyve never fit properly in my ears. You need to sing with your mouth pretty much on the microphone for it to pick up enough sound and the speaker is not great but its okay for a toy for a child which is what I intended it for. Length seems the same, so if you have a wide foot, go for your size but not in female. But I pretty much figured it out. I shopped around a lot, and settled on these to maximize space. Once mounted, the hook is very sturdy, unobtrusive, and convenient in our small laundry room. I have to hold it up to align the holes and slide the 15mm quickrelease through. So, Amazon must have been very limited in their choice of design. I just barely put a small amount in the center of my lip and it was wearable.
