I don't use wireless headphones because they are impractical and quality is low and I feel unconfortable to put wireless emitter almost in my brain.

I don't use 3,5mm jack on my phone as well, because output from S10e is terrible. So I connect fiio DAC via USB-C and wired Shure headphones to DAC.

I don't understand why anyone, who cares about sound quality, complainis about output, that crippling that quality.



The drivers in your wired headphones are also wireless emitters almost in your brain.


How something wired is suddenly wireless?


In reality there is no "wired" and "wireless". Things which are "wireless" just use the air as a crappy wire.

Anything with current flowing is creating electromagnetic fields. The wires and coils driving the magnets also act like little antennas and lose energy to the surrounding environment through RF radiation. In fact, it is exactly the property that the field exists outside of the wire which enables it to push/pull the magnet in the driver. It is the RF emissions produced by the coils that moves the magnet which pushes the diaphragm which makes the pressure waves you experience as sound.

This is why crosstalk on cables is an issue. This is why little transformers can cause issues with wireless devices. Everything electronic creates some kind of RF emission. Everything electronic is a wireless emitter.

You can even end up seeing the contents of a wired display because of the RF leakage of monitors. These aren't "wireless" by any measure, and yet their video can be detected and decoded wirelessly.
