I had not considered Etymotic HF5 because i thought they were over my budget, but it seems I can actually find them for 83 euros, shipping included.
Though i'm concerned about the comfort, I read they were really uncomfortable to some people. My ears aren't delicate flowers, but I sometimes listen to music for 6 or 7 hours straight. So how do they feel ? Are they really uncomfortable ?
Still hesitating (particularly between hifiman re-zero/re0 and the etymotics), other opinions are welcome.
The triple flange tips can be (very) bothersome in the beggining, I tried to push them too far and boy, that was horrible, but they isulated A LOT. I tried after the foam tips and when I belived there couldn't be more isolation, the stock foam tips are simply the most insulating tips I have ever found, and they are incredibly comfy too, but the problem is that they have 1 month lifetime.
After I found that I tried comply's , which for the HF5 I disliked, and then I came back for the triple flanges(which my friends always make fun of me calling a cristmass tree ¬¬) that are the ones I use today. The trick for me is that they need a deep insertion, but if you go too deep, they can be incredibly uncomfortable, but if you insert it just enough to seal, you have one of the best insulations on the market which is comfortable, although not in the same level as a comply, and praticle(no need to the smashing ritual of foam tips).
Finding the good tip for you can be incredibly hard, a thing that I'm descovering right now with my Westone 4R ¬¬" .
This is a very good price for the HF5, but make sure you are buying form an authorized resseler, so you can keep you warranty.
Also, I wouldn't sugest you listening 6-7 hours of music straight, principaly with a headphone or in-ear, try taking breaks in between.
I have never heard the hifiman's in-ears, my only experience with a hifiman was their dynamic fullsized HE-300, and it was pretty good, but I can't comment on those.
