Just to give you an update on how I am finding my Hydra 18 IEM. I am still loving the sound of it but I think in the long run a Hydra 22 would have been a bit better despite the slightly lower level of comfort behind the ears. I am getting a bit frustrated with the main bulk of the cable which is mostly because it is only two cables twisted together so it has lots of stored elastic energy within the cable which a normal four way weaved cable doesn't have. This stored energy leads to the cable sticking out in odd shapes unless you put it on and twist each part in a specific manner which if you are trying to do at 5am when I get up for my commute into London or on the train home packed full of people can lead to some irritation. I don't know if anyone has any advice on how to avoid this problem but I am guessing not due to the design which I should have worked out myself really. Very tempted to sell the 18 and purchase a 22 instead as like I said before it is still the best matched cable for my K10s that I have tried. Hope this helps people make their decisions on what to buy.
the sw22 is very flexible and lightand sounds stunning
+1 to that!
