44.1 is actually better since you get aliasing in hi-res recordings. They are called “Studio Quality” for a reason, the bits are more important since they determine the dynamic range and noise floor, which are actually audible. Even the CD quality exceeds the best analogue sources like magnetic tapes. Most people won’t hear a proper lossy compression from a lossless one.
Nah, hyper x clouds are crap in every aspect, except build quality. Once you try real headphones there is no going back.
