The Realme UI was officially unveiled today and amidst all the screenshots is a hint of an upcoming product – the Realme Buds Air Neo. Those can be seen in the Dual earphone connection screen in the settings.
The current buds don’t have active noise cancellation outside of calls so that’s one possible feature that Realme Buds Air Neo might bring.
As for the Dual Earphone feature, it lets you send different audio to wired and wireless headphones. For example, you can listen to music on your wired headphones and use a Bluetooth headset only for calls. This is just one of several features Realme is developing for its branch of Android.
Here’s the tease video, the Dual Earphone screenshot comes up at 0:06.
