For rock progressive / space rock ... Dendroaspis is perfectly valid and enjoyable, I enjoy them in that musical genre on a daily basis.
I think it is necessary to clarify about dendroaspis, reading comments gives the impression of not being recommended or being a real garbage. They have already spoken to you about the basses and subwoofers, but it is not that there is no bass, it is there, but it is not the protagonist, as an example the subwoofers do not rumble in your head and the drums do not have that extension in which you seem to notice the tension of the kick drum ... but ... what it does well it does very well, a clear, natural tone, wide sound, all the other frequencies, and more technical aspects in my opinion are superior to everything else I have heard, not a little higher, much higher. Sure, there are better ones, but it cost me € 52, which is important.
If we go to a bud with good bass options like ry4s plus, in my case I would choose dendroaspis every day of the year.
If you are looking for something low compared to iems, I think buds is not the place to look, if I want that flavor (I can live without powerful bass, but sometimes you want joy) and I use IEM as an example to help you use ZS7, Blon BL3 or Smabat Blackbat, but if I want a full sound I use another price range and to be honest there the bass is not the protagonist either.
We are also talking about a bud with a great metallic construction, light, small, with mmcx, it can be worn over the ear, and in my opinion cheap, and green ...
Edit.: Another thing of Dendroaspis Viridis, if I want to listen to metal for example, in my DAP with high gain the problem is over, if I want to listen to Pink Floyd ... it is not necessary.
