Got myself a pair of y40, at this price I cant think of anything that's better than them.
They were tuned for balance I would say, thicker on the low end, but not basshead style.
They are just new and haven't fully burned in yet, I am just gonna do some brief comparison of some portable on-ear's that I have tried based on my memories.
vs B&O h2: y40 is brighter than the very warm h2. y40 has similar bass as the h2, very smooth bass, a bit harder hitting though. Kinda like bose oe bass too. Vocal is thinner and crispier very small difference, I would say it is right in the middle of the mix. y40's top end is brighter than h2, still on the warmer side though. y40 has smaller soundstage.
vs v-moda xs: xs has tighter bass, more forward in low treble, vocals sounds crispier. Treble is brighter, about neutral with a sense of warmness. Larger soundstage.
It may look like that xs wins handsdown, in a monitoring point of view, maybe, but not enjoying music.
y40 is smooth, some say they are stereo sounding, alongside with h2, kef m500 or bose, but I think it does a better job in revealing and keeping it "real" than all of those. The largest con would be soundstage.
And it is really comfortable, definitely better than hard padding xs, better fit on large heads than bose oe
but.. why would it has a detachable cable design but not come with an extra audio-only cable
update: after some burn in, its vocal seems to be less bloated, crispier, tamer low-mids? Overall separation is better, soundstage didn't improve or very lightly.
Enjoying vocal in my k-pop track right now.
