Even with the angular design Andromeda is an extremely comfortable IEM, I have used them for 6h+ at a time with just a slight discomfort using the foam tips.

Having said that, the main issue I found with foam tips is they didn’t sound as good as the silicone ones such as JVC spiral dot or Symbio mandarin, those were in turn less comfortable.

What ended up being the best solution was getting a pair of custom tips from Custom Art those made them not only extremely comfortable but also further increased the soundstage.
