Yes, it's more fiddly if you want to chat with head phones on Switch due to the lack of any convenient way to combine both game and chat audio output. This is again, something that should be addressed. The point is that many people won't care about using headphones in most situations unless they're out in public. To those people who are playing at home, this setup is fine. Generally speaking, it's a concept that should be more fleshed out if it wants to be more useful.
See that's a reasonable thing to say. I can accept that. The only thing I slightly disagree with is:
"The point is that many people won't care about using headphones in most situations unless they're out in public. "
Again I like what I am talking about to be mostly private, even if of course my side is going to be audible to my housemates. Headphones have been bought for consoles for like a decade so clearly this isn't entirely true although you could argue that's necessity but I think for the most part it's also convenience.
You are being fairly reasonable with your point, I think you are just going a bit too far in denying the comfort and convenience most people have with headphones. Personally, I like them, don't use them for consoles much though.
