Hello I am very intrested in Audiophile sounds systems and headphones and music in general. I am quite young for this hobby so i don't generate income to get it for myself but I plan on getting a few systems and headphones in the future. I came across quite a few of "SOUND DEMO"s (headphones mainly) on Youtube recently and I didn't really understood the concept of them. Some of my friends told me that they are "useless" beacuse it depends what you are listening on so the only thing it can give back is ANC and passive noise isolation if the microphone is placed incide the cups. On the otherhand the tests were very carefully made and seemed pricey (which proves nothing but indicates that they could be legit). Can anyone clarify this for me? Do Sound Demos make any sense if I am not even using the headphones they use? (I watch Z reviews quite a lot but its not for everyone so be aware)
Thanks in advance.
