Bluetooth, we think, is a gift to the world. It is the alternative to Wi-Fi. In its current Bluetooth 5.0 generation, the technology is better than it has even been. Over a short distance, it is one of the best ways to transfer large amounts of data. It allows multiple devices to be connected simultaneously. It is also the most stable type of short-range connection you can get in your mobile devices today at ultra-low latency. 

That is why it is the preferred connection when it comes to your portable and wireless audio gear. Microsoft and Google have made it a point to allow for certified Bluetooth devices to connect to their devices much quicker and easier. The Quick Pair and Fast Pair functions saves us users a lot of time in connecting our Bluetooth gear. 

There is a problem with all these conveniences however, or rather, an inconvenience. Especially since multi-device connectivity is available on Bluetooth earphones, getting your devices or audio coming out from the right devices seems to be an issue today. For you to switch audio input from one device to the other is still a manual labour, no more inconvenient that just completely switching your Bluetooth earphone’s input source.  

Google Audio Switching 

According to Google’s blog post, their audio switching technology works on top of their Fast Pair algorithm. That also means that you do need to have a Bluetooth device that supports Google Fast Pair for it to work. Most new Bluetooth enabled wireless headphones today, save for Apple’s offerings, features Fast Pair anyway. 

They explained that using contextual information on what you are listening to, the algorithm automatically switches your audio input based on your actions. The algorithm is also highly dependent on audio prioritization to determine which audio source should be prioritized over which. For example, if your headset is connected to both your tablet and your smartphone and you are listening to music on your tablet and you received a simple notification on your smartphone, your gear should not be switching sources. When you get a call on your phone, for example, only then your audio source should prioritize the phone call and switch its source to your smartphone immediately. 

While there is a default priority setting to what your Bluetooth device prioritizes, Google is also giving users the ability to select and customize the experience on their own. At the same time, the experience will not only be limited to Fast Pair enabled Bluetooth audio gear connected to Android or Google devices only. The feature will also be available for all devices that support Bluetooth multipoint connection allowing you to have the convenience of quickly switching audio sources from your smartphone to your Windows laptop and vice versa.  

Currently, Google will be rolling out the new feature update to their own Pixel Buds Pro first. They say that they are rolling out the updates to their manufacturing partners like Sony and JBL over the next few weeks. From then on it is just a matter of time before the current line-up of Sony and JBL Bluetooth headsets get the update from the manufacturer’s end. You do not necessarily need an app to toggle audio switching as well, you just need to head into ‘Device details’ in the general Bluetooth settings page.
