When playing with headphones on Windows 10, from my experience, the game sounds awful. Whenever you break a block the sound is very stereo and only emits from the left or the right earphone depending on where the block is on the screen. For me this happens when I have my headphones in surround sound mode or stereo mode. Furthermore, the sound when breaking blocks in front of you is very hit or miss. The sound will either play at a decent volume or you won't hear it at all. 

To me it seems as if there is no proper directional/surround sound in the game which is the main reason why I'm still playing on the Java Edition. 

Not sure if this is a known issue or anything but my friends also have this issue on Windows 10 edition. I'm using the Logitech G930 headphones.
