Bluetooth, the headphone jack, or a USB dongle headset like the PlayStation headsets.
Using the built-in Bluetooth or an adapter? I wouldnt trust the built-in Bluetooth considering the joy con problem from the Switchs launch.
The headphone jack is inaccessible.
A third-party (or even Nintendo) could make that later. I think this is a this is what you get now solution. Same thing with Wii Us battery.
Are you kidding? This really isn't a difficult problem to solve. I'll quote myself from earlier:
Do you need more ideas?
Firstly, calm down. Secondly, I wasnt talking to you so I dont know why youre so flustered. Lastly Im not rooting for Nintendo. I know your years of gaming forum debates have you conditioned to be defensive but Im earnestly asking for a better solution.
1) I dont know much about Bluetooth so I cant give you a very accurate response, sadly, but doesnt distance between the two connected devices matter?
2) Where in the joycon could you put the headphone jack that would allow for the other features to work well AND allow you to comfortably hold one in each hand AS WELL AS one in both hands? Seems pretty difficult honestly.
3) The grip is the absolute cheapest product in the whole Switch package. Its just plastic... doesnt even have lights on it. Wouldnt adding a headphone jack require you to add other tech that would allow it to communicate with the console?
4) Are you talking about a different kind of grip?
5) This is the only weird thing to me but I assume its because they didnt want people to feel forced to buy a pro controller. Kind of a hey you want to voice chat but its your fault for not having a smartphone instead of you want to voice chat then buy our controller.
Support for the basic standards for voice chat on any normal system? USB, headphone jack on controllers, and bluetooth.
Even though its marketed as a home console lets all be honest. So with that out of the way, your options are the same as the above guys options. The only viable thing Ive heard is a USB dongle which sounds like a good idea but would require you to buy something just to chat. I think Nintendo is just trying to offer a free way to chat... without offering a paid way to chat for people that want it. :/
