LG G4 'earphone splitter' simultaneously uses Bluetooth and wired headphones

Here's a fun little feature on the LG G4 I didn't know about until today. You can (nearly) simultaneously listen to music on a Bluetooth device while also having something plugged in via the 3.5mm jack. The "earphone splitter" feature showed itself when I was testing some Bluetooth headphones and then plugged in a wired set. You get the option to use it or not. And while it's probably not something you're going to use very often, it's pretty handy if you need to.

There was a very short delay between the music on the wired headphones and the music through the Bluetooth headphones — far less than a second, but still noticeable.

Regardless, that's cool.
