Having swappable connectors is a plus for the ability to replace the most common point of failure on wired headphones.

Actually having to bring multiple connectors everywhere and swap them out more frequently than cables fail is a negative.

Both can be true at once.

So you would be okay with an XLR to lightning adapter or should Apple include an XLR plug on the iPhone too?

No, because I'd have to swap it out if I wanted to use a different device. As my second paragraph ays, having to swap it out frequently is a downside compared to my client device having a standard socket.

The headphone has a mini-XLR to 3.5mm connector built in. If it fails it's easy to replace. If the client device supports the standard 3.5mm connector it doesn't have to give a shit that the other end is XLR on IntelMiner's headphone (or in the case of my own headphones, 2.5mm for one set and 3.5mm for the other).
