Well, I am actually looking for some headphones for outdoor usage like KOSS Porta Pro. I know it's completely different type of product but both are open headphones and I need them to be this way. Somic's V2 are not foldable, have long cable and are much heavier but this is completely no problem for me as quality of sound should easily compensate it. I am not sure if they hold on head that much worse than Porta Pro's or some similar PX100's and such, but I know there isn't any big problem with KOSS/Seniheisers and I just don't see anything special in them neither. As for water, it's not about sinking them of course, but it's obvious that sometimes you can get caught by rain. Also wondering on durability, while cables look very solid and nice, what will happen when these headphones will fall down from desk or from head? Would they get damaged? This is where many quality portable headphones shine.
