Yep, phone and laptop, maybe I'll consider an amp someday, but right now I can't even estimate when and if. Many people say that momentum are not suited for long sessions if you haven't particularly small ears, but I can't find anywhere the measures of the pad.
Also the attitude to spend years in any decision that may affect you long-term (and maybe every other decision, like ordering a pizza).
Maze Neo 99 are available for around 200€, so unless it's like heaven and hell from any option around 150 I'll have to pass or wait. Regarding the difference it seems that they're smoother, mainly.
Lately I've been suggested Beyerdynamics Custom One Pro (which i can find on Amazon for like 120€), but whereas someone mention extreme clarity, other people state that the sound is a little muddy. I don't know if clarity and other non strictly related to the timbre properties could change depending on the mere bass amount, anyway I'm even more confused now. Same for the opinion that they're basshead headphones... Like, why nobody specify if they're talking about 3 and 4 level or about the hp overall?
One thing everybody seems to agree on is that they're extremely comfy, which would be a huge boost if they are actually good sounding.
