Big THANKS to Joker!!!
I ended up going with the A151. I just got them today and am trying them out. I really enjoy the clarity of the sound. I am finding them much more comfortable than my superfi 4. I am using the double flange tips. I don't have any problems with getting them in the right ear but for some reason the left ear always gives me some problems. I just need to get use to putting them in I guess. I know that the sound is the most important thing but I really like the cable....light and doesn't tangle and seems well connected.
Good to hear. Have you tried the single-flange tips? When these are worn cable-down the single-flange tips are actually pretty comfortable and give you more leeway in terms of size. It is not impossible that your right & left ear need different-size tips.
