With the latest firmware update for Nintendo Switch it seems that not only did there come clues about what that future Switch Pro that has been talking about for many months could be, but also information about Bluetooth audio support that would allow connecting wireless headphones without the need for third-party adapters.
Nintendo adds support for Bluetooth audio to the Switch

The latest firmware released by Nintendo for its portable console and the work of data miners is leaving us the most interesting information. A few days ago we commented on those two lines of code that referred to a possible base with a chip that would allow you to enjoy 4K content as well as the output of said video signal through a DisplayPort connection through the USB C port of the console.
Well, now it is a new dataminer that has found a reference to a novelty that this time would improve the user experience of any user with the laptop: support for Bluetooth audio. I mean, what you’ve seen is that Nintendo has added audio support to a Bluetooth controller that could allow you to connect any wireless headset to your console.
This, as you know right now, is not possible and without a doubt it is one of the main complaints of many users. Because it does not make sense that a portable console today only gives you as an option to enjoy your games in a more personal way and without disturbing others to use wired headphones.

With True Wireless type headphones so widespread, that you cannot connect your AirPods, FreeBuds or any other model of the hundreds and hundreds that exist on the market is a real nuisance for many. And if you want to do it, you have to resort to third-party accessories to connect Bluetooth headphones to the Nintendo Switch, through an adapter that goes to the USB C connector or via a 3.5 mm connection.
Will Bluetooth audio support make its way to the current or future Switch?

After the good news that Nintendo has added support for Bluetooth Audio, now the question is whether this is a novelty that will come to the current console in an upcoming firmware update or is it for the next generation of Switch.
According to the dataminer who has discovered this novelty, that it is there does not imply that Nintendo is going to make use of it in the current console. What’s more, it does not guarantee that you will use it. Because if the original Nintendo Switch launched in 2017 and the Nintendo Switch Lite in 2019, the company has certainly had plenty of time to add this functionality.
If you have not done it in all this time, even after receiving numerous criticisms for that online chat system where you had to make an absurd combination of cables next to your smartphone, why now? Maybe just seeing the current situation and how Bluetooth headphones are already normal or because what they are preparing is the future Switch Pro.
We do not know, we will have to be patient and see what happens with the next update and the rest of the company’s movements. But as a Switch user, beyond 4K resolution and other things, being able to connect your wireless headphones to your Nintendo Switch would be one of the things you most want to do right now.
