@Precogvision i wrote down the same comment in tanchjim’s thread with no result. It seems like you can help me (and maybe others)
„Is anyone own both Oxygen and Hana 2021? On some graphs new Hana seems to be more bassy than Oxygen (for example crinacle) which is a good thing for me. Also i wonder If there is any difference in technical performance. If it’s not a problem to pay a bit more for oxygen, are these any better than new hana? I wish there is a black or silver version of hana.. ”
I can say that the Hana 2021 sounds almost exactly the same tonally, at least within the scope of the units I heard. The Oxygen might be slightly more technical, but it's slim enough that I'd need to A/B to confirm (I don't own either, unfortunately).
