The same way you hear in 3D while only having two ears, but reversed.

Your ears are shaped such that when a sound comes from a certain direction, your ears physically alter it in a way your brain can understand. That lets you hear a direction. (Left and right are done by relative volume in each ear as well).

Dolby atmos and similar techniques apply filters to the sound that make it behave similarly to what your ear does, and that fools your brain into thinking the sound came from a specific direction.

It’s a tool not a solution. CICO is all the matters. I will say it’s very difficult to eat more than your daily allotment of calories in a a single meal or in a 4 hours time period. The problem is the zealots (like with most lifestyle trends) who treat it like the 2nd coming of Jesus.

They recommend an amp that does 2W @50Ω because amps are not rated for power in a standard method that accounts for the full frequency range. The headphone still only needs 1.5W max for 115db and that's 750mW per driver.

I dont know what you are on about with balanced = double voltage which means 4x power. Did you read that somewhere and not question it? Balanced does double the voltage, but the current does not change so power is only doubled.

You are applying opinions and feelings to physics.

As for the "happy customers dont complain" argument. It could be true.

But, when I see a user mentioning that their headphone broke, then the replacement also broke, as for example we have one post today about this happening to a Hifiman.

The argument is no long important. If QC issues are so common to hit the same costumer twice, the brand just doesn't care about QC.

It maybe even using the replacement service to bust consumer confidence in its shit product it sells. Instead of improve QC, if the later is more expensive.

The same way a 3D game can be seen on your 2D screen. The most common method is Head Related Transfer Function, it simulates the speakers placed in a room and places a head in the middle of it. What the simulated head hears at it‘s simulated ears. For more info look up head related transfer function and binaural audio.
