Yeah but...I don't understand the hype when 4/4 completely different people shared the same opinion about them, yet I rarely if at all see the same issues mentioned here.
Weird, but worst of all, irritating...very irritating :/
The X2 got hyped up by people who were either trying to get affiliate money or people who never heard an actually good headphone before.
I can well see someone without experience with Hifi headphone, who just came off another consumer headphone, thinking its actually good.
Personally I tested a pair just to see what it was all about quite some time ago and found the things fairly lacking in terms of sound quality (specifically limp, but mid bleading bass and grain across the board, especially treble, not to mention the wide but not well defined sound stage).
Also I have the feeling that you might be expecting bass quantity from the X2 (compared to the cloud), which since they are open back they just can not match that in comaprison to a closed back headphone. Generally hifi headphones (open back) do not feature nearly as much bass as most people are used to, as the bass has a tendency to hide detail which is the exact opposite of what hifi means. Most headphones just can not do quality, but controlled bass.
Personal recommendation is to return the things. If you want to try something cheap but open back that sounds better just try some KSC75 (which to boot also cost only 13$, so you might as well see what Budget-fi sounds like). Alternative if you just want to see how good bass sounds there is ofc the CAL headphones. Best introductions to hifi on a budget if you ask me and if you like any of those it might be worth investing more into Audio later down the line.
